Blue Jays can be a nuisance at
bird feeders, like crows they bogard their way into the feeding area scaring
songbirds away. They typically only give way to large woodpeckers; but they do
have a benefit – like crows they will chase hawks away. While the blue jays
might monopolize the bird feeders, they are little threat to the songbirds,
while hawks view smaller birds as breakfast, lunch, and dinner. Blue jays are
fighter interceptors when they see a hawk, swarming after it and chasing it
away – and while the blue jays are after the hawk the smaller birds are back at
the feeders.
I guess there is a sense in
which, if you are songbird, you learn to put up with blue jays knowing that they
can be beneficial. Life can be like that.
You have given me a new appreciation for blue jays! I didn't realizetheynwould do that. I have seen crows mob a hawk or an owl here.
