Pygmy Parrots – Thumb-Sized Lichen-Eaters that move like Woodpeckers

findiviglio — Wed, 16 May 2012 15:45:04 +0000

Hello, Frank Indiviglio here. I recently attended a fascinating lecture on Island Bird Diversity at the American Museum of Natural History. Two Pygmy Parrot species – the Red-Breasted (Micropsitta bruijni) and the Finsch’s (M. finschii) – drew the speaker to the Solomon Islands. In reflecting back on the talk afterwards, I realized that, despite my interest, I had yet to observe a live Pygmy Parrot. They’ve never been in the collection of the Bronx Zoo, where I worked for over 20 years, and only rarely appear in museums. Further research turned up one interesting field report, but it seems that we still know very little about these smallest and, arguably, most unusual of all parrots.

The World’s Smallest Parrots

Six species of Pygmy Parrots inhabit New Guinea, the Solomons and neighboring islands. They look, in most respects, like other parrots – but barely exceed a human thumb in size! At 3.5 inches in length, the Buff-Faced Pygmy parrot (M. pusio) is the smallest Psittacine; its relatives are not much bigger. Please see the video below…it is hard to believe they are real!

Singular Feeding Adaptations

Small size is not their only unique characteristic. Pygmy Parrots are believed to rely heavily upon lichen and tree fungus as food, the only parrots to do so. In 1942, the Red-Breasted Pygmy Parrot became the first Psittacine ever observed to feed upon fungus, which was described as a “jelly-like species growing on bark”. Unfortunately, our knowledge of its diet pretty much stalled at that point! While Kakapos, Keas and other parrots are known to consume lichen, only Pygmy Parrots have adaptations that allow them to specialize in harvesting it.

Adaptations to this odd diet include short tails with stiff, outwardly-projecting feather shafts, elongated toes and long, curved nails. Aided by these structures, Pygmy Parrots “creep” up and down tree trunks as they search for food; several have even been observed to move headfirst down trees (please see the accompanying photo of a nuthatch for an example). Similar structures have been evolved by woodpeckers, creepers and nuthatches, all of which also forage in the same manner as Pygmy Parrots. Woodpeckers and their relatives use this hunting style to find insects, not lichen; some (or all?) Pygmy Parrots consume insects as well as lichen.

Field Observations

An informative Pygmy Parrot article is posted on BirdForum.net, an interesting site where I sometimes record my own wild bird observations. Although not a long-term study, the notes detail some of the best field observations available (please see article below). The author worked on New Ireland, which lies in the Bismarck Archipelago, and spent some time observing the Finsch’s Pygmy Parrot.

Finsch’s Pygmy Parrots were most often seen foraging on Pometia tomentosa, a broadleaf tree. Local people confirmed that the birds, which are not uncommon, seem to favor that tree above others. Moving about like tiny squirrels, the minute parrots stripped bark from the trees, leaving characteristic scars. They seemed to be feeding on butterfly, moth or beetle larvae rather than lichen, at least when observed on Pometia trunks. Virtually nothing is known of their total diet, as observations are difficult once they enter heavy cover; as far as I know, Pygmy Parrots have never survived long in captivity.

Insect larvae may be a significant food source for the Finsch’s Pygmy Parrot, but more research in needed. Sadly, the parrots under observation abandoned the area after some boys harassed them with slingshots. It is not known how this species is affected by humans (other than being pelted with rocks!), but Pygmy Parrots generally seem able to adapt to modest habitat disturbance.

Learning More

I’m now searching The Auk and other sources for additional Pygmy Parrot information…anything that you might be able to pass along would be greatly appreciated, thanks.

Please check out my posts on Twitter and Facebook. Each day, I highlight breaking research, conservation news and interesting stories concerning just about every type of animal imaginable. I look forward to hearing about your interests and experiences as well, and will use them in articles when possible.

Green-Cheeked Conures – Captive Care and Natural History

findiviglio — Wed, 18 Apr 2012 16:35:45 +0000

Hello, Frank Indiviglio here. The decision to purchase or adopt a parrot requires careful consideration. For all their wonderful qualities, these intelligent, social birds are very demanding of one’s time and finances, and not suited to all homes. One species, however, stands out as an “almost” safe bet. The Green-Cheeked Conure (Pyrrhura molinae) adapts well to many different situations, and is less likely to display the behaviors that frustrate so many parrot owners. Although not trouble-free, it may well be the best choice for many parrot enthusiasts.

Pet Qualities

The word “fun” invariably arises when Green-Cheeked Conure owners speak about their pets. Even by parrot standards, they are curious and playful. Their affectionate nature and willingness to be coddled is often compared to that of a well-socialized cockatoo. These qualities, along with their small size, have skyrocketed Green-Cheeks into prominence in the pet trade. When I first began working for NYC bird importers in the 1970’s, they were unknown, and were uncommon as recently as 20 years ago.

Despite being a mere 10 inches in length, Green-Cheeks are surprisingly bold. Yet while they will defend themselves, most are good-natured if handled properly. Many enjoy “wresting” with their owners, pets such as rabbits, and even “bird-safe” dogs. Their demeanor suits them well to active, noisy households. They definitely take and interest in nearby hustle and bustle; several kept at large in a friend’s store act more like staff than birds, no matter how crowded it gets!

Although Green-Cheeked Conures do not have a reputation as talented mimics, many do learn to speak reasonably well, and even to use words in context (i.e. “Hi, I’m hungry!” when owner appears). Like all conures, their voices are harsh, but definitely on the “soft” side (by parrot standards!), and they tend not to develop screaming problems.

Other Considerations

Green-Cheeked Conures are highly social, and need companionship and interaction with other birds or people. An hour or so of contact each day is not sufficient. A pair will keep one-another occupied…considering their small size, this may be an ideal option for those with busy schedules.

Color Phases

Maroon, blue, gray and green all appear in the Green-Cheek’s plumage. Given the small natural range, there is a surprising degree of variation among the 6 described subspecies. Some ornithologists believe that their taxonomy needs revision, and that new species may be named in time. The Yellow-sided Conure, formerly classified as a distinct species, is now considered to be a color variation of the Green Cheek.

Fanciful names such as “Sun Cheek”, “Turquoise” and “Pineapple” describe the beautiful color morphs have been developed. Please see the article below for photos of each.

Range and Habitat

The Green-Cheeked Conure is limited in distribution to the Mato Grosso region of Brazil, northwestern Argentina and northeastern Bolivia. It generally stays within or near forested habitats.

Natural History

Despite its popularity in the pet trade, the Green Cheeked Conure has not been well-studied in the wild. A 2007 study, one of the few that focused solely on this species, indicated that a flexible feeding strategy allowed it to survive in diverse, harsh habitats (Braz. J of Biology, 2007 67(2):243-9).

In regions where some trees retained their leaves throughout the dry season, resident conures fed upon the flowers, seeds, fruit and/or arils (tasty structures designed to lure parrots and other seed-dispersers) of 16 tree species. Figs comprised 70% of the diets of Green-Cheeks dwelling in forests in which other dry-season foods were lacking. Please see the article below for further information.

Meyer’s Lorikeet – Natural History and Captive Care

findiviglio — Mon, 02 Apr 2012 18:46:01 +0000

Hello, Frank Indiviglio here. Most parrot aficionados know of the Meyer’s Parrot, but the beautiful green lorikeet bearing the same “first name” is relatively unstudied in the wild, and not commonly kept here in the USA. The Meyer’s Lorikeet (Trichoglossus flavoviridus mayeri), a subspecies of the Yellow-and-Green Lorikeet, differs from many related species in both coloration and social behavior. A forest-dweller confined to a single island, this unique bird deserves the attention of aviculturists now, while wild populations are still relatively stable.

Description

Three shades of green color the plumage of the 8-inch-long Meyer’s Lorikeet. The breast feathers and those behind the eye are tipped with yellow, and the bill is bright orange. While lacking the “flamboyant” reds and blues often associated with lorikeets, it is quite spectacular in appearance.

Range

The Meyer’s Lorikeet is endemic (found nowhere else) to Sulawesi, in Indonesia’s Greater Sunda Island chain. Sulawesi lies at a unique crossroad where animals originating in Australia and those from mainland Asia are found together. Over half of the island’s 125+ mammal species are endemic and most, such as the Anoa, Cuscus and Babirusa, are quite unusual and not well-known.

Although birds are more mobile than mammals, 34% of Sulawesi’s 400+ species “stay put”, and are found nowhere else on earth. Perhaps the most unique of these is the Maleo, the only bird that incubates its eggs by burying them in sand, in “crocodile-like” fashion (please see photo). Females test the soil’s temperature with specialized sensors in the bill, but other than adjusting the amount of cover offer no maternal care. Maleo chicks emerge from their subterranean nests well-able to fly and fend for themselves.

Habitat

Meyer’s Lorikeets are limited to mountainous forests (please see photo), where they reside at elevations of 1,700-6,000+ feet. The many shades of green that color their plumage render these arboreal feeders difficult to observe among the foliage.

They also appear in lowland areas where forests remain intact, and will sometimes venture out into open country when favored flowers are in bloom. However, both older and current accounts indicate that heavy forest cover is essential Meyer’s Lorikeet habitat.

These shy but noisy birds are often observed in the company of gaily-colored Ornate Lorikeets – quite a sight, I imagine!

Conservation

Meyer’s Lorikeet populations appear stable, but their status has not been well studied. Mountainsides within their range remain largely forested, which is a good sign. However, like all island endemics, they are especially vulnerable to habitat loss and other disturbances. The species is listed on Appendix II of CITES.

Meyer’s Lorikeets in Captivity

Meyer’s Lorikeets are not common in zoos or private collections in the USA, but have been bred by aviculturists in Europe and Asia. They are as “food oriented” as their relatives, but are somewhat shy initially and less likely to hand feed right away.

Although lories and lorikeets are notoriously difficult to house communally, especially during the breeding season (please see the article below), Meyer’s Lorikeets may sometimes be bred in small groups. They are best housed in an outdoor aviary (or, in cold weather, a bird room) that is equipped with a drain to allow for cleaning via hose. Spacious quarters, well stocked with branches and other diversions, are essential to the well-being of all parrots, but especially the very active and acrobatic lorikeets.

Loud shrill calls (please click here for a recording) are a fact of lorikeet life, and should be taken into consideration by prospective keepers.

Diet

Feeding is a major consideration in the husbandry of all lorikeets; none will thrive unless provided with a highly nutritious, carefully-planned diet.

Lory nectar mixed with a bit of molasses and soft food can form the basis of their diet, but this must be supplemented by other foods.

A wide variety of fruits and vegetables, including apples, pears, peaches, oranges, star fruit, kiwi, figs, banana, soft carrots, corn, Swiss chard, dandelion, and as many others as will be accepted, should be offered on a daily basis. Meyer’s Lorikeets will also take small amounts of millet and canary seed.

A paste of hard boiled eggs (ground with shells), egg food, cottage cheese and cooked carrots, sweetened with molasses, will provide necessary protein. Try mixing in some mealworms, crickets and other insects as well – I’ve found that some lorikeet species will accept these.

Lorikeets can be fussy…it is important to experiment until you find the proper mix or mode of presentation that works best in inducing your birds to accept the greatest variety of nutritious foods.

Barbets – Stunning, Unique Aviary Birds for Experienced Keepers

findiviglio — Wed, 21 Mar 2012 15:52:59 +0000

Hello, Frank Indiviglio here. Barbets combine gorgeous coloration and a unique body plan. Related to woodpeckers and toucans, barbets somehow bring both to mind. I’ve always enjoyed working with them, although a “barbet incident” gave me quite a scare early-on in my career…

“Frank, your barbet is on my fence.”

Some 3 decades ago, while still a novice bird keeper at the Bronx Zoo, I was working in a huge, densely-planted exhibit that housed a pair of Fire-Tufted Barbets (Psilopogon pyrolophus) and other Asian birds. My supervisor rushed in to say that one of my barbets was perched on a fence outside the zoo director’s kitchen window (he lived on the grounds). The director, an internationally-known ornithologist, was rumored to question the curators more closely about the death of “little brown birds” than giraffes. Unlike most exhibits, that housing the barbets did not have a double door, and I had often worried about escapes. So, I thought, there goes my dream job….

The barbets took an eternity to find, but they were in the exhibit. Other keepers had been dispatched to the director’s house, but the bird flew off before they arrived. The director was not known for practical jokes or drinking to excess, so I do believe that he saw a Fire-Tufted Barbet (even though they are not often kept as pets here …).

Description

Large heads, short tails, stocky builds and thick beaks surrounded by bristles at the base have led some to describe barbets as “odd” or even “clumsy-looking”. I prefer “unique”, and in any event the brilliant colors of most make up for any lack of “grace” in their body-plans. The Toucan Barbet (Semnornis ramphastinus), for example, exhibits light and dark blue, black, yellow, copper and bright red in its plumage.

The world’s 75-85 barbet species are classified in the order Piciformes, along with toucans (their closest relatives), honey guides and woodpeckers.

Range and Habitat

Barbets reach their greatest diversity in Africa, where 42 species (Family Lybiidae) have been described. Twenty six species, belonging to the Family Magalaimidae, are found in Asia. Most of the 14 species dwelling in Central and South America (Family Capitonide) are fantastically colored. The Toucan Barbets, (Family Semnornithidae) are also native to Latin America; 2 species have been described.

Most barbets are birds of forest interiors although some, such as the Coppersmith Barbet, inhabit city parks and gardens. The call of this 6-inch-long Asian native sounds like a hammer striking metal. The Coppersmith Barbet’s habit of issuing the call 80-100 times per minute, during the hottest part of the day, has earned it the nickname “Brain Fever Bird” (see video below). Elsewhere, various birds are given similar names…I must say that one dove species did annoy me during afternoons spent working in the hot Venezuelan sun!

Barbets in Captivity

Barbets require a large, well-planted aviary, and are sensitive to cold temperatures and damp conditions. Males may attack non-receptive females, and even larger birds of other species may not be safe. They are best kept alone or in pairs, although I had no problems housing Fire-Tufted Barbets with jay thrushes, bulbuls and Argus Pheasants.

Many individuals become quite bold in time, and will approach closely when offered favored treats.

All barbets are cavity nesters, with most utilizing tree hollows. Those that nest within termite mounds or underground are said to be capable of burrowing out of an aviary – not a capability one usually associates with birds!

Bearded, Gilded, Double-Toothed, White-Headed, Crested, Yellow, D’Arnaud’s and several other species are kept in the USA; please write in for specific information.

Feeding

Although typically thought of as fruit-eaters, many barbets are skillful hunters and nest-raiders as well. I’ve observed them capture anoles, spiders and other animals that were established in their exhibits. Understanding the natural history of the barbets you keep is essential if you are to succeed.

Most fare well on a diet comprised of a wide variety of fruits, berries, figs and dates. The fruit should be coated with a mixture of Insectivorous Bird Food, Softbill Select and Egg Food. Hard boiled egg and some cooked ground beef should be offered regularly.

Crickets, mealworms and other invertebrates are essential to the health of many species, and are indispensible for pairs with chicks; many also relish chopped pink mice. I maintain insect traps, such as the Zoo Med Bug Napper, to help meet the needs of the insectivorous birds under my care. Canned Invertebrates are a convenient means of adding variety to barbet diets.

Water for bathing is a must. Food sometimes collects among the bristles at the base of the bill and must be manually removed. Be careful when doing so, as barbets are capable of inflicting serious wounds with their powerful bills.

How Pink Pigeons Saved me from Life as a Lawyer

findiviglio — Tue, 06 Mar 2012 19:51:37 +0000

Hello, Frank Indiviglio here. First, I should explain the odd title. I grew up near the Bronx Zoo and dreamed of a career there since early childhood. Early on, however, responsibilities made it impossible for me to consider zoo work, a notoriously low-paying field. By the early 1980’s, however, things changed and I was volunteering at the Bronx Zoo and doing everything else I could think of to break into the field. But I was a lawyer at the time, and, despite years of experience with well-known animal importers and bird breeders, the zoo’s management did not believe I seriously intended to abandon such a lucrative profession. Then the Pink Pigeons came to the rescue…

“Thanks, Pigeons”

After a year of failed attempts, I managed to land an interview for a position as bird keeper. As the curator and I walked and talked, I caught sight of a group of unusual birds, and stepped closer. I thought they might be Pink Pigeons, Nesoenas mayeri. I was shocked, as there were but 12 individuals left in the wild at the time, and captive breeding efforts had only just begun.

The curator was surprised that I knew anything at all about the relatively unstudied birds. As luck would have it, I was smack in the middle of Gerard Durrell’s wonderful Golden Bats and Pink Pigeons, and so their plight was fresh in my mind. It also turned out that these rarities were the curator’s “pet project”. There were many highly-qualified candidates for the job, but in that moment, she made her decision and my life took on a new and fortunate course.

Breeding Pink Pigeons at the Bronx Zoo

One of my first rotations in the Department of Ornithology involved the breeding of Pink Pigeons and Birds of Paradise. We relied upon a technique known as “double-clutching” to bolster our Pink Pigeon population. The first eggs produced by each female were removed, whereupon she would lay another clutch. The first clutch was then placed under the care of a female Ring-Necked Dove.

Pigeons feed their young with “pigeon milk”, a unique food generated from the lining of the crop. Dove “milk” was suitable for Pink Pigeon chicks, but how they manufactured enough of it I’ll never know. Within weeks, the Pink Pigeon chicks were twice the size of their “foster-moms”. The doves would perch on the pigeons’ backs when brooding…looking like bizarre little “bird hats”!

My work with the pigeons was fascinating, and I threw myself into it with a passion. Due largely to the efforts of legendary conservationist Gerard Durrell, Pink Pigeons are doing better these days…I like to imagine that I have aided their recovery in some small way, and perhaps “paid them back” for helping me land my dream job.

Natural History

The Pink Pigeon is found only on the island of Mauritius, which lies east of Madagascar, off the coast of southeastern Africa. By 1980, deforestation, cyclones, and introduced monkeys, mongooses, cats and rats had reduced the wild population to 12 individuals. “Pigeon Wood”, a 15 acre stand of Japanese Red Cedar Trees, comprised their entire range.

Mauritius’ best known bird is the now-extinct Dodo, but other species, many endemic, have suffered as well. Kestrel, Fody (please see photo) and Fruit Bat populations plummeted, and both native tortoises were extinct by the mid 1800’s. The island is also home to the world’s rarest Psittacine, the Echo Parakeet (please see article below).

As was his way, Gerard Durrell took up the task of saving the Pink Pigeon from certain extinction. Today, over 350 individuals live on Mauritius, and the species is well-established in captivity. The Pink Pigeon story stands as a fine and all-too-rare example of what can be accomplished, even in the direst of scenarios.

Keeping Exotic Pigeons

The Rock Dove, or “city pigeon”, has given many of its relatives a bad rap, but bird enthusiasts know that the family Columbidae contains some of the world’s most gorgeous species. From fantastically-colored fruit doves to the massive blue Victoria Crowned Pigeon, a surprising number are well-established in captivity. Please see this article for further information.

Parrot Conservation in India – Poaching Threatens most Native Species

findiviglio — Thu, 01 Mar 2012 17:01:24 +0000

Hello, Frank Indiviglio here. Parrot conservation news is usually dominated by stories covering large, popular species, such as African Greys, Black Palm Cockatoos and Amazons. While interest in these threatened birds is commendable, I also find it useful to focus my reading and writing on less well-known parrots and parrot habitats; for example, please see this article on Echo Parrot Conservation. Today I’d like to address parrot conservation concerns in India.

India’s Parrots and Parakeets

India is home to 12 parrot species, but, overshadowed by the needs of country’s tigers, rhinos and elephants, they have a hard time competing for public attention and funds. Adding to the problem, perhaps, is the popularity of the Indian Ring-Necked Parakeet, a hardy species that has established feral populations in such unlikely places as NYC. The fact that all of India’s wildlife is protected by law furthers the false sense of security.

Most Indian parrots belong to the genus Psittacula, and are collectively known as Ring-Necked Parakeets. Also native to this hub of bird biodiversity (over 1,300 avian species have been recorded) is the amazing Vernal Hanging Parakeet, Loriculus vernalis (please see this article). Most natives are poorly studied; one, the Intermediate Parakeet, has never been seen in the wild, and may be a captive-generated hybrid.

Extent of the Black Market Trade

It has been illegal to collect any native Indian bird since 1990. However, Indian poachers, more organized than those in most other countries, are proving especially difficult to stop. In fact, they seem a breed onto themselves – recently an individual was arrested while trying to kill a rhino…in a zoo!

Studies and confiscations reveal that 8 parrot species are regularly taken from the wild. Of these, the Nicobar, Long-tailed and Derbyan Parakeets are classified as Threatened or Near Threatened by the IUCN. The most widely-collected species is the Alexandrine Parakeet; please see the article below for updates on a recent seizure of Alexandrine Parakeet chicks.

As chicks aged 3-4 months dominate the trade, losses among captured birds are high. Although it is common knowledge that wild-caught adults make poor pets, they too are collected. Most of the contraband parrots are sold in Mumbai, Delhi and other large cities, while others are smuggled out of the country through Nepal, Pakistan and Bangladesh.

Identification Poster Distributed

In cooperation with several other organizations, TRAFFIC India has recently produced a poster (please see image link below) depicting all of the subcontinent’s parrots. Designed to help people distinguish native, protected species from their imported relatives, the poster will be distributed to conservation, forest and railway authorities, police departments and schools.

Please also post your questions and comments below…I’ll be sure to respond quickly.

Echo Parakeet Conservation – World’s Rarest Parrot, Back from the Brink

findiviglio — Wed, 01 Feb 2012 19:30:01 +0000

Hello, Frank Indiviglio here. The Echo or Mauritius Parakeet (Psittacula eques) population was reduced to 10-12 individuals by the late 1970’s, and remained at similar levels into the next decade. Thus, it had the dubious distinction of being the world’s rarest parrot. Thanks to the efforts of the Durrell Wildlife Conservation Trust, the World Parrot Trust, and the Mauritian Wildlife Foundation, its future is now somewhat brighter. However, the Echo Parakeet is still one of, if not the, most endangered parrots on the planet, yet receives little of the attention granted the Kea and other better-known species.

Former Home of the Dodo

The birds of Mauritius, a small island nation in the Indian Ocean, southeast of southern Africa, have a troubled history. The infamous and now extinct Dodo lived there, and the Pink Pigeon, Mauritius Kestrel and other endemics (species found nowhere else) are barely holding on.

Legendary conservationist Gerard Durrell became interested in their plight decades ago, and the organization he founded continues his work today. Mr. Durrell’s work has influenced me greatly (in fact, his efforts to conserve Pink Pigeons are partly responsible for my being hired by the Bronx Zoo…but more on that in the future), so it is with cautious optimism that I read of some recent progress on the Mauritius.

An Overlooked Species Rebounds

As Echo Parakeet numbers continued to decline, most major conservation groups concentrated their efforts on Keas, Black Palm Cockatoos, Kakapos, the parrot trade, and other popular species and causes. Confined to a nation that drew little international attention, the Echo Parakeet seemed doomed to extinction. But the Durrell Trust persisted and, aided by the aforementioned groups, has pulled the species back from the brink.

As of February, 2011, there were approximately 550 Echo Parakeets on Mauritius, prompting the IUCN to down-list the species from Critically Endangered to Endangered. The release of captive-bred individuals, supplemental feeding and nest site creation slowly but surely turned the tide.

Introduced Parrots and other Threats

Unfortunately, however, the Echo Parakeet’s future is far from secure. Only one percent of its original habitat remains, and some of the threats to its survival are difficult to erase.

In a sad coincidence, one of the most serious problems is posed by its close relative, the Rose-Ringed Parakeet (Psittacula krameri). Introduced to Mauritius some time ago, Rose-Ringed Parakeets are aggressive colonizers that even manage to survive in “the wild” in NYC (please see article below). They out-compete the Echo Parakeet for nesting sites (tree hollows) and food. They may also interbreed, and so in time will overwhelm the Echo Parakeet’s gene pool. Introduced Honeybees also displace the birds from nest sites, which even in intact habitats are always in short supply.

Other threats include egg and chick predation by Black Rats, which are highly arboreal (as their alternate name, Roof Rat, suggests), agricultural development, and habitat alteration caused by pigs and other domestic animals.

Disease Outbreak Sparks New Concerns

A recent outbreak of Psittacine Beak and Feather Disease is of great concern. While stable populations can endure natural disease cycles, Echo Parakeet numbers are very low, and the entire population dwells within a single, tiny habitat. One major disease event could, in theory, kill every remaining bird. Likewise, the effects of typhoons and fires will be magnified.

Researchers continue to battle the disease, drawing from lessons learned when working with other endangered parrots. The Cape Parrot, Africa’s rarest, has also been hit by Psittacine Beak and Feather Disease. Please see this article to learn what is being done to prevent this species, and the Echo Parakeet, from going the way of that other Mauritius endemic, the Dodo.

Conserving the Gouldian Finch – How One Man’s Efforts are Making a Difference

findiviglio — Fri, 06 Jan 2012 16:17:17 +0000

Hello, Frank Indiviglio here. The brilliantly-colored Gouldian Finch is something of an avian anomaly. One of the most sought-after of all cage birds, it is bred in huge numbers by aviculturists worldwide. Wild populations, however, are in serious decline, and have been so for over 30 years. But, in conjunction with governmental and private groups, one dedicated conservationist is helping to brighten the species’ prospects.

Taking Action

Self-made millionaire Michael Fidler was first captivated by Gouldian Finches over 40 years ago, when he chanced upon a group in a store in Manchester, England. From that point on, he has been concerned for their future. And while few people can afford to follow in his footsteps, his efforts illustrate the importance of doing whatever is within one’s abilities on behalf of conservation. Be it through money, ideas, teaching or a new observation, we all have some potential to help.

Fire Management Changes a Unique Habitat

The Gouldian Finch is limited in distribution to Australia’s tropical north (please see map), where its lifestyle and feeding habits are uniquely influenced by rain and fire. Having evolved in a harsh, ever-changing habitat, the Gouldian Finch is, in many ways, highly specialized.

For millions of years, fires and varying rain cycles necessitated a diet comprised largely of grass seeds for one part of the year, and insects for another. Researchers believe that modern fire management practices are the most important reason for the 30-year-long decline in Gouldian Finch numbers…and despite 20 years’ worth of conservation programs, the downward trend continues.

Cattle Ranching

Gouldian Finches first began having problems in Queensland, on the eastern edge of their range. Studies indicate that the population declines progressed westward…just as did the change in fire management practices and the growth of cattle ranching.

Cattle consume grasses upon which the finches depend, and the manner in which they feed stifles re-growth and encourages the establishment of non-native plants. The spread of cattle ranching has also been implicated in the recent scarcity of other animals, including the Carpentarian Rock Rat and the Partridge Pigeon.

Eco-Tourism and Release Programs

Conservationists believe that many species will benefit if birding is encouraged as a form of eco-tourism on cattle ranches, but progress has been limited. Captive-bred Gouldian Finches are easy to come by, but when released into the wild most are quickly captured by kites, hawks and other avian predators.

Noble Efforts

Mr. Fidler relocated from his native UK to New South Wales, Australia, and now lives close to prime Gouldian Finch habitat. Over the past 20 years, he has donated vast sums to Gouldian Finch conservation programs and personally participated in captive and field research. One gift of $600,000 has helped to insure the survival of central Kimberley’s Gouldian Finches, one of the largest remaining populations.

Mr. Fidler also funds researchers at the University of New South Wales, and allows them access to his huge private aviary, home to several hundred birds…hats off!

The WorldBirds Data Base – an Exciting Conservation Tool Open to all Birders

findiviglio — Fri, 23 Dec 2011 18:31:29 +0000

Hello, Frank Indiviglio here. Established in 2003 by Birdlife International, the WorldBirds Birdwatcher’s Data Base now has 16,000 regular users and over 3 million recorded observations. Unlike many professionally-organized efforts, WorldBirds is open to ornithologists and casual and serious birders alike. It is an excellent, enjoyable way to contribute to worldwide conservation projects and communicate with others who share your passion.

Your Observations Count

Research fund availability and the sheer scope of what needs to be done places severe limits on conservationists…paid professionals can not handle everything. Even when I worked for the Bronx Zoo and other well-funded organizations, I relied heavily upon volunteers. Much of the data that later found its way into professional publications was generated by them, not I.

Fortunately, birders tend to write things down – not only life lists, but also details concerning habitat, weather and so on. This information can be invaluable to those working on projects ranging from single-species protection to international migration flyway monitoring. Observations of even very common birds may be very useful pieces of larger conservation puzzles.

Using the WorldBirds Data Base

Anyone can record their observations on WorldBirds (please see link below) or use it to learn such things as where to find specific birds or what sightings might be expected in various places. Other useful features include news updates, assistance with planning birding trips and species checklists for many regions.

And, of course, you’ll have the satisfaction of knowing that your observations may be used to advance important conservation efforts for rare birds and threatened habitats. Children are encouraged to participate and to view their contributions as valuable. From Red Shining Parrots to Snail Kites and mangrove swamp preservation (please see photos), you can learn and participate on some level via WorldBirds.

Related and Independent Efforts

WorldBirds currently has a presence in 160 countries, and is managed in the USA by the National Audubon Society. When all the data bases that link to it are considered, the number of recorded observations far exceeds the 3 million+ registered on the main website. In Portugal, a whale and dolphin monitoring function is being added.

Observations recorded by birders have proven useful in the management of several Important Bird Areas and to the functioning of the Wintering Bird Atlas, Breeding Bird Atlas, Common Bird Monitoring Project and other efforts sponsored Birdlife International.

Several important projects based in the USA also rely upon the efforts of “everyday” birders, and all are easy to become involved with, and quite enjoyable. One of the most ambitious, the Christmas Bird Count, is right around the corner! Please see the articles linked below for details.

Winter Bird Feeding – Rare Bird Update and Some Useful Products

findiviglio — Tue, 13 Dec 2011 15:03:52 +0000

Hello, Frank Indiviglio here. Winter brings with it unique bird-watching opportunities, as cold weather forces otherwise-shy species to visit feeders in search of food. Rare visitors driven south by severe weather and others blown off course during migration also brighten birders’ days. Today I’d like to alert you to several new (and standard) bird feeding products, and highlight some ways to see the unusual avian visitors to your neighborhood.

Birding Surprises

Wherever you are located, winter birding is an exciting prospect. Often, unexpected birds tend to stay put for quite awhile, due to disorientation and the need to remain near a newfound food source. Checking with the many on-line and telephone services (yes, phone-based reports still exist, check here!) is a great way to remain aware of what’s going on nearby; if luck is with you, you can then go out and see the bird that has been reported.

Local birders in and around NYC have already posted sightings of Snowy Owls, Nashville Warblers, Lincoln’s Sparrows and Winter Wrens. In Los Angeles, recent notable visitors include Eurasian Widgeons, Short-Eared Owls and Mountain Bluebirds. Regularly checking the North American Rare Bird Alert or your local Audubon Society chapter will keep you informed about both unusual and regular avian visitors.

Winter Bird and Wildlife Feeders

Winter drives squirrels to even greater food-stealing efforts than usual. The Bird Buffet Squirrel Proof Feeder and similar models will help to thwart them. If squirrels, raccoons, opossums, cats or other animals become a serious problem around your feeders, you may wish to consider a humane live trap (please write in for advice if you are not experienced in animal trapping).

Some folks, myself included, enjoy watching the antics of Red, Gray and Flying Squirrels. The Combo Squirrel Feeder can be set to serve either or both furry and feathered visitors.

Suet Feeders should always be available to provide high protein foods to Nuthatches, Woodpeckers, Creepers and other insect specialists.

Winter Foods

While most any appropriate food will be useful, certain items are especially suitable for harsh weather, when energy needs and other factors influence both people and wildlife.

No Mess Patio Mix contains hulled seeds; ideal for severe weather when it is difficult to clean up around feeders, or anytime you are not physically able to do so (and you’re not paying for shells, only seeds!).

Peanuts, cracked corn and Squirrel Logs are ideal for those who wish to feed squirrels, chipmunks, deer and other mammals. Many birds, including Bobwhite and California Quails and various doves, also relish cracked corn. Peanuts will attract Blue Jays, Monk Parrots and numerous others.

Wild Delight Food Blocks are available in a variety of mixes that are specifically formulated for finches, woodpeckers and general use. Protein and energy-rich Suet Bars and the newer Suet Pellets are important winter standards for woodpeckers, chickadees and many others.

Quails, Doves, Pheasants and other ground-feeding birds are especially at risk following heavy snows. Birdlover’s Quail, Dove and Pigeon Mix spread about on a cleared patch of ground will help them to get by.

Nuthatches, Thrashes, Woodpeckers and many other birds continue to feed upon hibernating insects, and their eggs and pupa, throughout the winter. Freeze-dried mealworms will be greatly appreciated by both insectivorous and omnivorous birds.

Extras and Fun Items

The simple wooden Audubon Bird Call that we currently carry is the exact same model I used over 40 years ago! While I can’t say I ever accurately mimicked any bird, the sounds I created caused just about every species to stop and look around, allowing me a better view without scaring them away. I even used it while working at the Bronx Zoo, in order to attract the attention of meerkats, bald eagles, flying squirrels and all sorts of other creatures…a unique item that should be useful to photographers as well.

A supply of open water is a very important but often over-looked winter necessity. A Birdbath De-Icer will simplify the task of providing water when temperatures drop below freezing.
