WIU Biological Sciences Professor Brian Peer's research paper about a bilateral gynandromorph bird — a bird with a brownish-gray feathered appearance of a female cardinal on its right side and that of a male cardinal's red feathers on its left side — was recently published by The Wilson Journal of Ornithology and was then featured in Science magazine.
The Northern Cardinal was spotted several years ago in Rock Island (IL) by Peer and his colleague Robert Motz and was observed... between Dec. 2008 & March 2010. The two researchers documented how the cardinal interacted with other birds on more than 40 occasions during that time period and how the bird responded to calls.
"Our paper represents the most detailed observations of a bilateral gynandromorph bird in the wild," said Peer. " We never observed the bird singing and never saw it paired with another cardinal. It was one of the most unusual and striking birds that I've ever seen." Read more about Dr. Peer's research at http://bit.ly/1ED3azs
