For the amateur who has gained a degree of proficiency in handling canaries, there is hardly a more fascinating phase of the hobby. We welcome questions from those who undertake this work.
DISTINGUISHING THE SEX OF CANARIES
We have seen many experts sex canaries, and have come to the conclusion that the best proof that a canary is a hen occurs when she produces an egg, and likewise, that her companion is a male, if the egg is fertile. However, there are many other characteristics associated with the sex differences of canaries.
For example, the cock canary:
1. Sings 2. Has a bolder eye and look about the head 3. When in breeding condition in the spring, has an elevated vent which definitely protrudes like a wart.
The hen canary, by contrast,
1. Does not sing 2. Is not so bold about the eye and head 3. Has a flat, unelevated vent.
These characteristics are all subject to exceptions. We find good males that do not sing, good hens that do sing; males of one strain having a female appearance about the head when compared with hens of a heavy strain of birds, and vice versa. There are also cases where the vent areas of both male and female are very similar except when in breeding condition.
Errors are most likely when a breeder sexes spring hatched canaries in the fall. The breeder will separate the observed singers from the non-singers, as male and female. Then he goes through the non-singers for some indication in the appearance of the head or vent area, and makes a further tentative separation. Such division can only be moderately reliable, because only a few strongly sexed young males tend to come into breeding condition early. An error of as much as 25% is not unusual in fall sexing.
For your guidance a good indication of a young male canary is that he sings with a noticeable swelling of the throat. From January and February on through June the male in breeding condition will have a noticeably raised vent as well as strong song. In pairing birds it may be expected that any male in breeding condition will pair with any female in breeding condition, providing there is not a very great difference in size.
