That Bird Blog – Bird Care and History for Pet Birds

Surprisingly, a rare little bird from South America is responsible for all the red and orange Canaries (Serinus canarius) in existence today.  Known also as the Venezuelan Red Siskin or the Black Hooded Red Siskin, this brilliant songster (Carduelis cucullata) “donated” the red genes responsible for the birds that have come to be known as Red Factor Canaries.

A Pairing of Different Species

New color phases of birds are produced by breeders all the time, but the story behind Red Factor Canaries has an odd twist.  Usually, species within the same genus are bred together during such experiments.  Canaries and Siskins, however, are not all that closely related, and are not even classified within the same genus. 

What About Color-Enhancing Foods?

Although natural foods containing carotene and commercial Color-Enhancing Diets can brighten the reds and oranges in Canary plumage, genes put the color there in the first place.  The same principle applies to other species as well – early on while working at the Bronx Zoo I learned that if I did not mix enough whole red shrimps into the Chilean Flamingo food, the birds took on a “bleached-out” appearance very quickly – which angered the zoo’s director, who had collected the birds himself!

Fertility Problems

Originally, male Siskins were mated to female Canaries, and the chicks exhibited characteristics of each.  These hybrids were then bred back to Canaries, and eventually a bird that looked just like a Canary, but sported the gorgeous plumage of the Siskin, was developed – and thus we came to have Red Factor Canaries.  The male offspring of a Siskin/Canary cross are only partially fertile, and females are usually infertile.

Fertility among Red Factor Canaries is still not high; breeders usually find it necessary to utilize pure Red Hooded Siskins as breeding stock from time to time.

In Part II we’ll take a look at Siskin care and natural history.

Australia’s Grass Parakeets (Genus Neophema) are so beautifully colored and graceful in flight, that it almost seems like they “should be” delicate and difficult to keep.  Yet they are very hardy, fairly quiet with pleasant “songs” and quite confiding and easy to tame.  Please see my article Introducing Australia’s Colorful Grass Parakeets to learn about their many good points.  Today we’ll meet a few of the more popular species.

Difficulty in breathing is often a bird owner’s first clue that something is amiss.  Wheezing, nasal discharge and other problems that seem related to breathing may in fact arise from any number of ailments.  Read More »

When ornithologists use the term “finch”, they are usually referring to birds in the Family Fringillidae.  However, the “finches” kept by pet owners are more often of the Family Estrildidae – the waxbills, weavers and sparrows.  Today we’ll take a closer look at the Family Fringillidae, the True Finches.

Classification and Range

The 140+ species of True Finches range across all continents except Antarctica and Australia.  The most commonly-kept birds in this family are the Bullfinch and the European Goldfinch.  The American Goldfinch, is a close relative and, in captivity, interbreeds with its European cousin.  Most True Finches are classified within the Subfamily Carduelinae. They nest solitarily and defend only the area around the nest.  Mated pairs forage with others in loose flocks.  Read More »
