Use the following tips to identify the gender of
your bird(s):
Birds which sing or dance while singing are (almost
always) cocks.
Birds which lay eggs are hens.
In a sexually dimorphic pair, the cock is the more
vibrantly colored and/or elaborately marked of the
two birds, especially during the breeding season.
In many species, the male's seminal glomerulus will
push the cloacal wall into a prominent projection
(called the cloacal protuberance or cloacal promontory)
during the breeding season. This causes the area surrounding
the vent to protrude more in cocks than it does in
hens. When the breeding season is over, the vents
of the two sexes appear similar.
