Half male half female cardinal! - Magical Realist - Dec 26, 2014 Never seen this before. The creature is literally halved right down the middle! It's called a gynandromorph. Imagine a human gynandromorph. (shades of old Star Trek episode..) "This bird might look like a holiday ornament, but it is actually a rare half-female, half-male northern cardinal (Cardinalis cardinalis, pictured with female plumage on the left and male plumage on the right) spotted a few years ago in Rock Island, Illinois. Researchers have long known such split-sex “gynandromorphs” exist in insects, crustaceans, and birds. But scientists rarely get to extensively study a gynandromorph in the wild; most published observations cover just a day or so. Observers got to follow this bird, however, for more than 40 days between December 2008 and March 2010. They documented how it interacted with other birds and even how it responded to recorded calls. The results suggest being half-and-half carries consequences: The cardinal didn’t appear to have a mate, and observers never heard it sing, the researchers report this month in The Wilson Journal of Ornithology. On the other hand, it wasn’t “subjected to any unusual agonistic behaviors from other cardinals,” according to the paper. Intriguingly, another gynandromorph cardinal sighted briefly in 1969 had the opposite plumage, they note: the male’s bright red plumes on the right, the drabber female feathers on the left."=====http://news.sciencemag.org/biology/2014/12/half-male-half-female-bird-has-rough-life RE: Half male half female cardinal! - C C - Dec 27, 2014 Never imagined such a dictotomy being expressed so neatly by an animal's outer covering without any artificial contrivance being involved.
