Bird Flight, Unlike most animals, some birds -- about 10 percent of the 10,000 or so species identified as of 2013 -- participate in interspecies mating, according to Irby J. Lovette, director of the Fuller Evolutionary Biology Program at the Cornell Lab of Ornithology, in a 2013 New York Times article. Most birds mate for only one season – and only one reason. This is because, in most bird species, the female makes the final decision to reject or accept a male that courts her, and often does this on the basis of being "impressed" by signs of fitness such as brightly colored feathers. size. We have a scoring method to record the cloacal protuberance condition: 1=conical, 2=tubular, 3=bulging. Photo of Dickcissels courtesy of Andy Reago & Chrissy McClarren at Flickr.

About 1 or 2 percent of sperm released by the male reach the sperm-storage tubules of the female, which lie near the junction of her vagina and her uterus. Because many of the hybrids born of interspecies unions die young or are otherwise incapable of passing on their genes themselves, this process is not considered to be evolutionarily successful. While numerous characteristics set them apart from other creatures commonly kept as pets -- they fly, they lay eggs, they have feathers -- birds are distinctive in various reproduction-related ways as well.
