Canary Types – an Amazing Array of Color, Size, Shape, Plumage and Song

For a somberly-colored bird, the Canary (Serinus canaria) has made quite an impression on us.  Shipwrecks, vicious dogs and thievery all figured into the captive history (please see article below) of what is now the most popularly kept finch.  Selective breeding has also resulted in an array of different types, some of which are barely recognizable as Canaries.

The First “Type” Canaries

CanaryDifferent Canary varieties (termed “types”) first developed quite by accident.  Canaries arrived in Europe in 1478, when they were taken to Spain from their native habitat on several islands off Northwest Africa.  As the Spanish sold only males and travel was difficult, Canary owners usually bred related birds to one another.  This increased the likelihood of mutations, including the yellow coloring that is now considered to be the Canary’s “normal” color (wild Canaries are actually greenish-brown).  Read More »

Hand Rearing Black-Headed Mannikins and Other Finches

Black headed Finch
While working for a bird importer in years past, I had the opportunity to hand-raise a number of finch chicks.  The following information is based on recent and past experiences with the Black-Headed Mannikin (Lonchura atricapilla), also known as the Black-Headed Nun or Munia, but could be applied to a number of related birds.

The youngest chicks I’ve worked with were 4-6 days old and, like most Mannikins, had hatched in a domed nest (please see photo).  They were reared in plastic containers lined with dry grass in an incubator set at 90 F (range: 86-93 F).

Feeding Nestlings

I feed very young finches at 2 hour intervals, from 5 or 6 AM to midnight at first, and cut back over 2 weeks or so to 6 AM – 8 PM.  Hand Rearing Formula (warmed per directions) offered via syringe serves well as a base diet.  Although not strictly necessary, to this I add a “drop” of peanut butter and 2 drops per syringe of sunflower oil.  A bit of cooked egg yolk and a drop of Avitron, provided three times weekly, completes the feeding regime.

Despite their delicate appearance, healthy Mannikin chicks are ravenous.  After a few days, they develop the amusing habit of raising one wing in order to ward off competitors…mini “jousting matches” sometimes break out!

Young Mannikins can only take a small amount at each feeding, and will choke or aspirate food into the lungs if it is forcibly squirted down their throats.  The safest way to feed them is to gently release from the syringe just enough food to fill their mouths…at a frequency of every 2 hours, this will provide quite enough nourishment.

Care of Fledglings

Black headed Finch NestUpon fledging, the chicks should be fed on a 6AM – 8PM schedule until they begin pecking at food on their own.  Most begin trying solid food on the fifth day after fledging, but this varies widely…close observation is very important at this point.

Their first meals should be offered on the cage floor, not in cups, to assure that they are aware of its presence.  Seed-based Finch Nestling Food, Egg Food and cut sprouts should be available at all times.

Once the fledglings have begun to feed regularly on their own, you can gradually reduce the syringe feedings to 2-3 times per day.  Continue this schedule until they lose interest in the syringe, which may take an additional 2-3 weeks.  It is a mistake to rush the weaning process – birds decline in condition very rapidly at this age, and poor nutrition during the fledgling period will have lifelong consequences for their health.

Black-Headed Mannikins and related birds prefer to sleep in a nest or enclosed space, even outside of the breeding season.  Fledglings raised together usually crowd into one covered nest, but provide extras in case of aggression.

Although generally quite hardy as adults, Mannikins are cold-sensitive as chicks.  Until you are certain that their immune systems are functioning well, take extra care to keep the youngsters warm at night (a hot spot of 86-90 F, with an ambient temperature of 80-82 F, works well).  A red or black night bulb, designed for use with reptiles, will provide heat without disturbing their day/night cycle.

Light and Color Vision in Birds – Improving our Pets Quality of Life

Recent research on avian vision at Sweden’s Lund University has revealed that birds lose their ability to see color at twilight.  These findings have inspired me to consider how we might use lighting in order to improve the health and breeding potential of captive parrots, finches, doves and other birds.

The Findings

The article, published in the Journal of Experimental Biology, points out that birds need 5-20 times the amount of light as do humans in order to see color.  By day, birds have extremely sharp color vision, and see both UVB light and a far greater range of colors than do people.  However, their color vision disappears at twilight – far earlier in the day than does that of any other animal studied thus far.

Light’s Effect on Captive Birds

I believe it is important that we consider the type of light we provide to our birds…the zoos in which I have worked are now experimenting with full spectrum lighting in their bird exhibits.

Poor light quality and intensity may explain the difficulties experienced in breeding otherwise hardy bird species in captivity.  Light can have some unexpected implications for reproduction.  Captive female desert iguanas (lizards native to Southwestern North America), for example, rarely reproduce unless given full-spectrum lighting…without UVB light, they cannot see the pheromone trails laid down by males.

Similar scenarios are likely at work where birds are concerned.  Indeed, there are indications that proper levels of UVA and UVB light encourage natural behaviors, reproduction and strong immune systems in captive birds.

Providing Birds with Appropriate Light

Fortunately, a number of options are open to bird owners.  Exposure to natural sunlight (bearing in mind that glass and plastic filter out UVB rays) is the best of these, but when this is not possible a high quality Full Spectrum Bird Lamp should be utilized.

Further Reading

The new findings on light intensity should be valuable in explaining certain aspects of bird evolution and behavior.  For example, the chicks of Gouldian, firetail and zebra finches, all of which nest in dark tree hollows, sport light-reflecting nodules near their mouths.  To read more about this survival strategy, please see my article Flashy Finch Chicks.

 

The Top 5 Websites for Budgerigar (Parakeet) and Cockatiel Enthusiasts

Sorting through the scores of bird interest websites can be very taxing, so I thought I’d highlight some especially good ones here (listed in alphabetical order).

Budgerigar Websites

While most clubs and societies focus on English Budgerigars, which differ a bit from the race more familiar in the USA (please see the article referenced below), English Budgerigar husbandry and natural history information will be useful to all Budgerigar owners.

Budgerigar Society

Based in the UK, the Budgerigar Society was founded in 1925 and boasts over 3,000 members – quite a reserve of expertise!

In addition to hosting exhibitions and providing a wealth of information on show standards and related matters, the society is committed to disseminating health, husbandry and conservation news, and does a fine job of it.  The posted research articles, many written by recognized experts, are top-notch.  The new Budgerigar owner, however, should not shy away – a series of wonderful articles for beginners is also available.

Great Western Budgerigar Society

Founded in 1952, this US-based society is one of the largest devoted solely to the care and exhibition of Budgerigars, and promotes the advancement of both scientific research and practical husbandry techniques.

It is well-known for hosting some of the country’s most popular shows…one of these, which featured over 1,300 Budgies, was the largest ever held in the USA.  I was particularly pleased to find wonderful photos of the various Budgerigar color types and printable Nest Box and Egg Log Cards.

World Budgerigar Organization

This international organization does a fine job of bringing together Budgerigar experts and enthusiasts from all over the world – governments should cooperate half as well!

At least 21 countries, including the USA, are well-represented.  I especially admire the group’s efforts in funding the translation and dissemination of important research articles.  Budgerigar show standards and conservation-oriented lobbying are also high priorities.

Cockatiel Websites

National Cockatiel Society

Now in its 25th year, the National Cockatiel Society is a great resource for aviculturists seeking information on any aspect of Cockatiel care or exhibition.

The website’s library is one of the most impressive I’ve seen, with many of the posted articles having applicability to other parrot species as well.  Specific interest areas, such as those for breeders and exhibitors, assure that no site visitor will leave unsatisfied.

North American Cockatiel Society

In contrast to many Cockatiel interest groups, the North American Cockatiel Society focuses its efforts on pet care as opposed to exhibition (however, the well-researched information on Cockatiel genetics and mutations will prove of interest to both pet owners and those who exhibit birds).

I was happy to see that fact and fun strike an excellent balance on this website – the articles are well-written and informative, and the “Just for Fun” section is most entertaining.  The “Frequently Asked Questions/Tips” feature covers just about all one might need to know when getting started in keeping cockatiels, while a chat-room and “Cockatiel of the Month” photo serve to liven up the visitor’s experience.

Further Reading

The race of birds that has come to be known as “English Budgerigars” is larger (and, some say, quieter – apartment dwellers take note!) than the Budgerigars more typically seen in the USA.  Please see my article The English Budgerigar for more information.

The Cockatiel’s life in the wild is less well-known than is its captive care, but very interesting.  To read about Cockatiel natural history, please see The Cockatiel in Nature.

 

Bird Reproduction – How Natural Social Behaviors Affect Captive Breeding

Bird breeding is rarely as simple as putting a male and female together and hoping for the best.  Even Budgerigars and others that been captive bred for thousands of generations remain influenced by ancestral behaviors.  Understanding this will greatly improve our success at keeping and breeding birds in captivity.

Social Behavior in General

Macaws, Amazons and Conures in EcuadorThe majority of pet trade birds are highly social creatures.  Although they may squabble during the breeding season, the presence of flock-mates is a strong breeding stimulus.  Indeed, many aviculturists cite the absence of additional individuals as the main reason for breeding failures among well-bonded pairs.

Even reliable captive breeders such as Budgerigars may not reproduce if held in single pairs.  The addition of another pair, or even housing the pair within sight or hearing of others of their kind, often spurs nesting.

Aggression (Adults)

Despite the fact that group situations may encourage breeding, we must also bear in mind that birds living together form themselves into cohesive flocks.  Newly introduced individuals, even those suitable as mates for unpaired birds in the flock, may be attacked, especially during the breeding season.

Oddly enough, larger flocks are often more peaceful than small groups (a rule that I’ve found applicable to creatures ranging from fishes to baboons!).  Aggression tends to be meted out among several as opposed to 1 individual, and non-target birds often “get involved” and divert aggressors’ attentions.

Aggression (Chicks)

In most cases, youngsters should be removed from their parent’s cage once they are feeding on their own.  Otherwise, they may interfere with the rearing of later broods, or may be attacked by the male (monk parrots and other colonial nesting species are often exceptions).

Usually, smaller, short-lived species (lovebirds, parrotlets), and those that inhabit harsh environments (grass parakeets) are likely to attack newly-fledged youngsters   Such birds are evolutionarily adapted to reproduce often, or to be ready as soon as the unpredictable rains arrive, and so are usually eager to re-nest.  However, despite being opportunistic breeders, budgerigars and cockatiels are often tolerant of fledglings.

Macaws and Other Long-Lived Birds

Hyacinth MacawsLarge, long-lived parrots usually raise only a few chicks each season, and may not breed every year.  Unlike the species described above, most inhabit environments that offer predictable weather patterns and food sources, and so they can “afford” to spend a great deal of time in imparting survival skills to their young.  Macaws, African Gray Parrots and similar species are, therefore, usually quite tolerant of their youngsters long after they have left the nest.

Mate Choice

Birds can be quite choosy (maddeningly so!) when it comes to mate selection.  This is especially true for macaws, Amazons, African Grays and other long-lived parrots.  Their pair bonds span many decades, so it behooves them to “get it right” the first time (I’ll avoid here the obvious parallels one could draw regarding our own species!).  If you are intent on breeding, it would be prudent to purchase a bonded pair or individuals that mutually groom and spend time near each other.

Some species deviate from the usual “parrot pair model”.  Certain Australian Parakeets, for example, have “difficult” relationships outside of the breeding season…they remain as a pair, but the females become somewhat aggressive towards the males.  In the close confines of captivity, they can make life quite miserable for their unfortunate mates.  As always, research your pet’s natural history thoroughly.
