Blue jay: Difference between revisions

Blue Jays have dark gray legs and feet, light gray to white breast feathers, and a blue crest on top of their head. Their wings are blue with white and black lines crossing horizontally and a blue tail with black bars on top and white bars underneath. Their eyes, feet, and beak are black. They grow to be about 10-11 inches in length[http://www.enchantedlearning.com/subjects/birds/printouts/Bluejayprintout.shtml] and 2.5 -3.5 ounces. [http://animals.nationalgeographic.com/animals/birds/blue-jay.html] The crest on the top of their head is lowered or raised according to it's mood. When it is excited to aggressive, it's crest feathers stick straight up. [http://www.shawcreekbirdsupply.com/blue_jay_info.htm]

The male and female look identical to each other except that the male is slightly larger. [http://animaldiversity.ummz.umich.edu/site/accounts/information/Cyanocitta_cristata.html]

Their feathers aren't actually blue, it's the refraction of light. If the wings were crushed, the blue pigment would disappear. During the summer they shed all their feathers, most likely to stay cool during the summer heat. [http://www.birdhouses101.com/blue-jay-facts.asp]
