People seem to have mixed
reception to Blue Jays. Some welcome them to the feeders, enjoying
their striking coloration and beauty. Others find them a nuisance,
often because of a concern that they chase off desirable songbirds and
have a reputation of killing other species' nestlings and destroying
eggs. I don't have knowledge of studies confirming or denying the
reputation that they kill young chicks and destroy unguarded eggs.
But I do know that I have yet to observe a Blue Jay driving off other
birds. They rarely come near the bird feeders where other species
are already present. Instead, the Jays I observe stay well out on
the fringes of the yard and feed from the seed that I sprinkle around an
old tree stump and are quick to fly off when other birds approach.
What I have read about them in online field guides is that they are
capable of mimicking a hawk's cry and will give that cry in warning of
danger, which benefits all species of bird in the vicinity who are
sensible enough to flee from a hawk.

There is no difference in plumage or coloration
between male and female Blue Jays, and plumage stays consistent
throughout the year. Indiana is a year-'round range for Blue Jays.

For as loud as they are and large as they are,
the Blue Jays seem incredibly shy. This Jay investigated a new
hopper/platform feeder combination my husband installed for me recently.
So far, the House Sparrows are the dominant visitors but with luck, this
Jay will come back with reinforcements.
