Planting Oaks

Blue jays bury thousands of acorns each autumn, carrying them kilometers, and forget many. They may have helped oak forests to move north after the Ice Age, because oaks spread faster than seeds falling from the tree could explain.

Blue Without Blue Pigment

There is no blue pigment in the feathers. Tiny air pockets in the feather keratin scatter blue light. If a feather is crushed, the blue disappears and it looks brown.

Smart and Social

Jays imitate hawk calls, which may warn other birds or mislead rivals, and use tools in captivity. See Common Raven.
