Blue Jays

The Blue Jay is most closely related to the crow. Its behavior is similarly bold and brash. Sometimes it even raids the nests of other birds.

It is difficult to find a nest of a Blue Jay, for they are very quiet around them. However, if the nest is threatened it will be aggressively and fiercely defended.

A surprising fact about the Blue Jay is that its feathers have no blue pigment, for they actually are black and white. The blue color results not from pigmentation but from the refraction of light, similar to refraction in a prism.

The plumage for both sexes is identical, and the term for this is "monomorphic."
