Ocellated Turkey: The “Other” Thanksgiving Turkey

Male Ocellated Turkey

Uploaded to Wikipedia Commons by Bruno Girin

Stories about the North American Wild Turkey (Meleagris gallipavo) and its domestic cousins abound as Thanksgiving approaches. And certainly this impressive and economically important bird is worthy of attention (please see articles linked below). But there is another turkey – and only one – a breathtakingly beautiful bird that is largely overlooked by zoos and private aviculturists alike. I had the good fortune of working with this species, the Ocellated Turkey (Meleagris ocellata), at the Bronx Zoo. Bringing to mind a turkey-peafowl hybrid, this fascinating bird is threatened by poaching and habitat loss, and deserves more attention from bird enthusiasts. Today I’ll take a look at its natural history and captive care.

 

Description

The male Ocellated Turkey’s body is clad in a mix of highly-iridescent bronze and green feathers; in the sun they are truly spectacular. The hens are a bit less-brilliant in color, but still very attractive. The blue-gray tail feathers are adorned with large, round blue and bronze spots (ocellus). The bright blue head and neck bear red and orange nodules, which are more pronounced in males.

A blue crown, which becomes larger in the breeding season, tops the male’s head; red eye rings develop at this time as well. The leg spurs, used when battling other males, are noticeably larger than those of the North American Wild Turkey (please see photo).

 

Somewhat smaller than their North American relative (and much smaller than barnyard versions!), males usually top out at 11-12 pounds in weight.

 

Range

The Ocellated Turkey is found in Mexico and Central America, where it ranges from the Yucatan Peninsula to central Belize and northern Guatemala.

Habitat

Ocellated Turkeys inhabit brushy grasslands, thorn scrub, open lowland forests, rainforest edges, riverside thickets and abandoned farms. Open habitats are utilized during the breeding season, but they never wander far from thick cover.

 

Diet

The natural diet appears to be as varied as is that of the North American Wild Turkey. Leaves, berries and other fruits, nuts, seeds, small snakes, lizards, spiders, worms, insects and other invertebrates are taken with equal relish. Field studies indicate that chicks subsist largely upon insects, but captive born youngsters take a wide range of foods.

 

From egg to adult, Ocellated Turkeys face predators ranging in size from coatis and snakes to pumas and jaguars. Consequently, they remain wary and alert even after several generations in captivity.

 

Ocellated Turkeys in Captivity

I kept Ocellated Turkeys in heavily planted-outdoor exhibits provisioned with heated shelters. They were somewhat high-strung and always on guard, but did fine as long as dense cover was available. I do not believe they would thrive in bare exhibits. Although some European zoos allow their turkeys outdoor access on warm winter days, those I’ve worked with seemed quite cold-sensitive and were kept indoors during the late fall and winter.

 

Ocellated Turkeys are not fussy eaters and readily accept commercial turkey chow, but I strove to provide a great deal of dietary variety. They especially favored the crickets, mealworms and other insects I tossed in most days, and continually searched the leaf litter for snacks at other times.

 

Breeding in zoos is sporadic, with more success being had in Europe, especially Belgium, than in the USA. They are rare in private collections, and remain very expensive.

 

Status in the Wild

Ocellated Turkeys are classified as “Near Threatened” by the IUCN and are listed on Appendix III of CITES.

 

They are hunted, often illegally, throughout much of their range. Males lose much of their characteristic caution during the breeding season, and make easy targets as they display in open grassy areas. Habitat loss to logging and agricultural expansion also threatens their survival.

 

Even in undisturbed habitats, their apparent “tastiness” to non-human predators results in significant losses. One study found that 85% of the chicks hatched in June did not survive until September; 30% of the breeding hens were taken by predators during the same time period.

 

The Ocellated Turkey’s stronghold appears to be in the Maya Biosphere Reserve of Guatemala and northern Belize, but detailed surveys are lacking.

The Best First Bird: My Choice for “Perfect Pet Parrot”

Gray Cheeked Parrakeet

Uploaded to Wikipedia Commons by markaharper1

Choosing a “Best First Bird” from the hundreds of captive bred species is very challenging because personalities vary so much among the same species. The qualities you seek in a pet should guide your decision.  For example, do you want a quiet bird, one you can interact with, or a pet to observe in a large flight cage with a mate? Bearing that in mind, today I’d like to introduce you to my hands-down favorite parrot, the Gray Cheeked Parakeet or Pocket Parrot (Brotogeris pyrrhopterus). Also known as the Orange-Winged Parakeet, this delightful bird is an excellent choice for those new to parrot keeping and without the space needed for large species. And trust me, its attractiveness will not dim as you gain experience, for those of us who started out keeping these little guys remain enamored of them decades later. No doubt my experienced readers will have other favorites; your thoughts will be of great value to novices, so please share your experiences by posting below. Please also post below if you’d like advice on choosing your first finch or softbill.

 

Pet Qualities

The ease with which Gray Cheeked Parakeets adjust to human companionship is my primary reason for recommending them to folks without parrot-keeping experience. Within their native range, it is said that even wild-caught adults make fine, handle able pets. Captive born youngsters, even if not hand-raised, offer new owners the best chance of obtaining a friendly, hands-on companion. One may even be able to train an adult that has little human contact…a virtual impossibility with many other species.

Of course, taming and training must be done properly…please post below for further information. But it is worth the effort, as well-adjusted Gray Cheeks are the most charming, affectionate and entertaining avian pets one could hope for!

 

Midway in size between lovebirds and cockatiels, Gray Cheeks are small enough to accommodate in most homes, and generally not quite as noisy as many parrots. They also break the parrot mold by tending to bond with all familiar people, rather than to their primary caretaker alone. Despite their diminutive size, well-habituated Gray Cheeked Parakeets are usually quite fearless, taking on dogs, larger parrots and strangers indiscriminately. While very amusing to observe, this aspect of their personality can get them into trouble, so watch yours closely!

 

Gray Cheeks do not have a reputation as talented mimics, but some individuals do quite well in learning to repeat words and sounds.

 

A number of the Gray Cheek’s relatives, including the lovable Bee Bee Parrot, are popular among bird enthusiasts (please see photos) and also suitable for beginners. Please see the articles below and post any questions you may have.

 

Description

The 6-8-inch-long Gray Cheeked Parakeet is clad in various shades of yellowish to bright green, and sports blue highlights with a gray chin, forehead, and cheeks (no surprises there!); small bright orange feathers decorate the under-wings.

Range and Habitat

The Gray Cheeked Parakeet occupies a limited range in Ecuador and northwestern Peru, where it may be found along moist and dry forest fringes, in thorn scrub, and on ranch and farm outskirts.

 

Status

Wild populations appear to be much reduced from former years, due to over- collection for the pet trade and habitat loss. Certain sections of their range now lie within protected areas, so there is at least some hope for their future survival.

 

When I started working for bird importers back in the 1970’s, Gray Cheeks rivaled Budgies and Cockatiels in popularity. Breeders here in the USA did not make up for the shortfall caused by the prohibition on importing wild parrots, so that today captive-born individuals are not always easy to find. However, they are well-worth searching for!

 

Housing

Although not very large, Gray Cheeked Parakeets are quite active and, like all parrots, are prone to stress-related disorders when kept in small enclosures. Large cages or aviaries stocked with a variety of parrot toys are ideal, and daily out-of-the cage time is essential. Pairs that are closely confined may over-preen one another to the point of severe feather loss.

Diet

Fruit and greens figure highly in the natural diet, and are essential to your pets’ long term health. Provide your Gray Cheeks with a wide variety of fruits and vegetables on a daily basis, and be sure to search out “exotic” varieties if these are not available from your usual store. Pomegranate, prickly pear fruit, apples, kiwi, carrots, peas, corn, dandelion, kale and many other types of produce will be readily accepted (introduce new foods slowly to avoid digestive upset).

 

The balance of the diet should be comprised of a good small parrot seed mix. Dried fruits and vegetables are relished, and may be used as training aids.

 

Breeding

Breeding should be given more attention by pet keepers, especially given this species precarious status in the wild. So far, results have been sporadic, but this may be due to a lack of interest, given the huge numbers of inexpensive, wild-caught animals that were available early-on.

 

Gray Cheek clutches average 4-6 eggs, which are incubated for 24-30 days. Only the female incubates, but the male often sits beside her in the nest hollow – the mothers among my readers must, I’m sure, wonder just how “useful” this is!

Dutch Law Prohibits Hand-Rearing Parrots

 

 

Dutch Law Bans Hand-Rearing of Young Parrots: What’s Your Opinion?

HAND REARED COCKATOOS

Uploaded to Wikipedia Commons by Snowmanradio

This month (July, 2014) the Netherlands became the first country to outlaw the hand-rearing of parrots. The law covers all Psittacines, including parakeets, cockatoos and lovebirds, and imposes fines and/or jail time upon violators. Bird breeders and private owners may not remove nestlings from their parents before the young are feeding on their own and otherwise independent; species-specific time frames are set out in the legislation. The process of hand-rearing, long touted as a means of bonding parrots to people, has been linked to a host of behavioral and health problems. While several countries extend similar protections to young dogs, cats and monkeys, the Dutch law is the first to include birds.

 

Bird breeders and owners worldwide are lining up for and against this ground-breaking law, and discussions have sometimes become heated. Where do you stand? Please let me know by posting your thoughts and opinions below.

 

Health Concerns (Physical and Mental)

While hand-reared parrots initially bond readily to their caretakers and so seem ideally-suited for life as companion birds, research conducted at the Netherlands’ Clinic for Birds (please see article below) suggests that problems often arise as the birds mature. Groups that have long lobbied for this law, including the Dutch Parrot Foundation, argue that parent-rearing is essential to such intelligent, social birds. Weakened immune systems, certain diseases, severe behavioral problems and other concerns have been linked to hand-rearing.

Breeding Failures

Also, parrots that bond with humans often refuse to accept mates once they mature. Throughout my career, I have seen this occur in animals as diverse as Great Horned Owls and Gorillas, and it is generally irreversible. This phenomenon even extends to birds fostered by closely-related species. In zoos, the eggs of rare birds are sometimes pulled and placed below a hen of a related, more common species. This causes the rare female to produce a second clutch, increasing the potential population. Such chicks often identify with their foster species…in some cases imitating their call and preferring that species as mates. There are no set rules…Pink Pigeons fostered by Ring-necked Doves did fine for us at the Bronx Zoo, but human-reared birds of many species proved to be poor breeders.

Does Hand-Rearing Perpetuate Bad Husbandry?

While critics of the new law abound, advocates believe that other countries will follow the Netherlands’ lead in time. I found one point raised by the Dutch Parrot Foundation to be particularly interesting, and in line with what I’ve observed over many decades of animal-keeping.

 

When environmental conditions and health are not ideal, captive animals curtail reproduction. With very few exceptions, this holds true for all taxa, from invertebrates to mammals. And when captives do breed, many species will refuse to raise the young, or may even kill and consume them, if all is not well (for example, many first-time hamster keepers learn the hard way that disturbing a new mom by frequently checking her litter invariably leads to disaster). Strange as it may sound, such behavior makes good sense, from a survival standpoint – parents do not waste time and resources caring for offspring that will not likely survive.

 

The same holds true with parrots. Some of the law’s opponents claim that hand-rearing saves lives, because so many parrots refuse to incubate eggs or abandon their chicks. However, the Dutch Parrot Society maintains that a pair’s failure to care for their chicks is a clear indication of bad husbandry practices. A poor chick-rearing record should be seen as a call for more research and better living conditions, not as an impetus to remove the chicks from their parents. Viewed in this way, one might say that chick-pulling allows sub-standard husbandry practices to continue, and does little to add to our understanding of certain species’ needs.

 

According to those who favor the law, once parrots are provided with a proper species-specific diet, suitably-sized and designed enclosures and other appropriate conditions, both breeding frequency and parenting success will improve. My experience with the Bronx Zoo’s huge, diverse bird collection, and with many other animal groups, also bears this out. Well, I’m not sure how this information will be received, but I’m betting there will be sparks! Please post your thoughts below.

Smart Birds: Cockatoos Solve a Complex Five-Step Puzzle

Goffin's Cockatoo in flight

Uploaded to Wikipedia Commons by Marah09013

Think you have a smart parrot? That may be, but a Goffin’s Cockatoo has recently set a new standard by which bird – and indeed animal – intelligence will be measured. Pipin, as the avian genius is known, demonstrated a skill previously known to exist only in chimpanzees. Using sequential problem solving abilities, Pipin (and, after a time, several of his “lab partners”) figured out how to open 5 different locks – each of which jammed the next lock, and each requiring a different physical maneuver – in order to obtain a treat. Mastering the task, which took nearly 2 hours, required the bird to solve problems, remember what he learned and apply it to a different task, and focus on a distant reward…and, I assume, to have patience!

 

The Experiment

The fascinating research into Psittacine intelligence was conducted at the University of Vienna, and published in the journal PLoS ONE (8(7): e68979;doi: 10.1371/journal.pone.oo68979; 7/13). Ten Goffin’s Cockatoos were presented with a box containing a treat. The door to the box was transparent, so that the birds could see the treat (a nut) within, and was secured by 5 locks.

 

Lock number 1 had to be opened before the cockatoos could get to lock number 2, which had to be opened in order to gain access to lock number 3, and so on. Opening each lock required a different physical action – removing a pin, screw and bolt, turning a wheel and shifting a latch.

 

Without prior training, Pipin opened the box in less than 2 hours. The article stressed the speed of his problem solving, which of course is impressive. But I’m equally surprised by the fact that he could keep at a problem for such a long time. As anyone who has tried to train parrots (or toddlers!) knows, their attention spans are relatively short (or so I thought…maybe birds and 2-year-old children have been tricking me all along!).

 

Five other “less-cerebrally-gifted” but still quite intelligent Goffin’s Cockatoos solved the puzzle after watching Pipin perform or following exposure to each lock individually.

Researchers Make the Test More Difficult

 

Sequential problem solving requires a parrot or person to remember and then apply what has been learned, and to work for a distant reward. In order to test these and related abilities, the University of Vienna researchers scrambled the locks, so that number 3 was first in line, followed by number 5, etc. Once a cockatoo had mastered a lock, it rarely became confused if the lock’s place in the puzzle was changed. And locks that were disabled by the researchers (left unlocked) were given a quick glance and then ignored.

Abandoned Baby Birds: What to Do When You Find a Baby Bird out of the Nest

Uploaded to Wikipedia Commons by benjamint444

Hand-rearing a bird that seems abandoned is an extremely difficult process. If you’ve observed wild baby birds in their nests – calling continually for food and greedily gulping down whatever their parents bring, this may be hard to believe…seems most would be very easy to satisfy. However, there are a great many factors to consider, fine points that are not well-known and potential health problems that are all-too-common. As a lifelong zookeeper and licensed wildlife rehabilitator, I’ve raised many nestling birds representing a huge array of species – and none were easy! Today I’d like to highlight some important points one should consider before taking on the very tedious job of raising a young wild bird.

 

Note: The following information is general in nature, designed to provide an overview of what to expect. Please post below for detailed advice on hand-rearing specific types of birds.

Immediate and Future failures – Be Prepared!

Those who take in orphaned wild animals of any type are generally kind-hearted souls who take losses personally. But death and failure cannot be avoided, and may be the rule rather than the exception. Baby birds that fall from the nest often have internal injuries, and are usually weakened by parasites, lack of food, and exposure to the elements. Turning the bird over to an experienced rehabilitator is usually the best option; please post below if you need help in locating a local rehabber or veterinarian.

 

If they survive, hand-raised wild birds often have difficulty with socialization, and may be rejected by others of their species. A Great Horned Owl I helped to rear tried to feed mice to its keepers when it entered breeding condition, but fled from other owls…a good educational animal, but not suitable for release. Captive-reared birds may lack survival skills, and their immune systems may not serve them well under natural conditions.

 

Attention to Detail is Critical

Until fully-feathered, young birds typically need to be kept at 85-90 F. Commercial rearing foods used for seed-eating hatchlings must be properly prepared and cooked, then served at the ideal temperature (generally 101-104 F) many times daily and, at least early on, 1-5 times each night.

 

While it appears that parent birds merely stuff food down their chicks’ throats, feeding is actually a very delicate procedure, and small mistakes can lead to death by asphyxiation or infection. As birds open their mouths for food, the glottis closes and the food winds up where it belongs. Weakened nestlings that do not beg are often “force-fed” by well-meaning rescuers. Food and liquid provided thus usually wind up in the lungs, resulting in a quick fatality.

 

The condition of the chick’s crop must be monitored carefully, even if the youngster is eating well and appears hungry. Due to the nature of artificial diets and other factors, crops may fail to empty or retain air. Infections inevitably follow.

 

Dehydration is common, especially at typical household humidity levels and for birds that are not feeding eagerly. The water content of your bird’s food must be carefully monitored and adjusted as the bird grows and different foods are offered.

Eager Feeders May Still Face Troubles

Wild nestlings are provided with dozens to hundreds of different food items by their parents. The diets of most, even those species that are confirmed seed-eaters as adults, are comprised largely of insects, spiders and other invertebrates. The nutrients they contain are impossible to duplicate artificially. As a consequence, birds that survive hand-rearing often exhibit growth and immune system abnormalities.

 

Transferring a youngster to the adult diet can be tricky, and can result in losses even when all else has gone well. Depending upon the species, an entirely new diet or additional food items will be needed. Some switch from insects to seeds and/or fruit, insect eaters and birds of prey begin taking whole animals, and so on…these drastic changes must be accommodated by the bird’s digestive system. Nestlings that have not been properly nourished may not be able to adapt.
