Note 57 — NATURAL HISTORY OF CAGE BIRDS. (continued 5)

Green birds, bullfinches, and even chaffinches, yellowhammers, and the like, have been tried; but the difficulty augments with the difference of species and food: for example, I have never seen a male canary very fond of a female yellowhammer, nor a male of the latter kind of a female canary, though the plumage may be selected so as to offer a striking resemblance. An ardent bullfinch will sometimes yield to the allurements of a very ardent hen canary. I have myself witnessed it; but with every care, it is seldom that the eggs prove fruitful, and produce young. Dr. Jassy, however, writes me from Frankfort, that he has obtained mules of a bullfinch and canary, by making other canaries sit on the eggs and bring up the young; and that this plan is pursued in Bohemia. A tufted or crested female should never be chosen, because this ornament is very unbecoming to the large head of a mule. “My bullfinch,” he adds, “is so attached to the female canary that he mourns all the time they are separated, and cannot bear any other bird.”

I possess a nightingale which, having been for a long time shut up with a female canary, lives very sociably with her, and sings as usual; indeed, he was so ardent in the spring, that he paired with her in my presence, but the eggs were unproductive. I shall try next spring, if the same thing happens, to give the eggs to another sitter.—Author.
