Blue Jay

Today, while at Vanderbilt, I saw a Blue Jay over by the Student Health Center. It was in the bushes right by the sidewalk, and seemed to not mind the passersby at all. I thought it was strange that it wasn't the least bit afraid of humans. It actually let me get pretty close to it.

Here is an interesting fact about Blue Jays, taken from Wikipedia:
"As with other blue-hued birds, the Blue Jay's coloration is not derived by pigments, but is the result of light refraction 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."
