H, I,.....K, L (#55)

This is obviously a Jay. I was hoping that this was a Scrub Jay, but it's just a plain old obnoxious Blue Jay. It's head is crested, and there is a black collar around the neck.





Wikipedia says that the blue color, like other blue hued birds, is not from a pigment. "It is the result of light interference due to the internal structure of the feathers; if a blue feather is crushed, the blue disappears as the structure is destroyed. This is referred to as structural coloration."

How about that.
