Hello!

I have been trying for a week to figure out what kind of bird is in my tree, but I am at a loss. I'm a very novice birder, just like to ID what's in my yard.

There are couple of birds that I haven't been able to get a full-on look at that live in a tree in my yard. They are incredibly noisy, mostly in the morning and a little before dusk. The sounds are a godawful screeching baby-strangling sort of noise, and when they make the screams, their whole body flutters. It seems like it's some kind of aggressive display against the bluebirds that are also in the tree.

From what I can tell, the birds are white underneath and darker on top - kind of a greyish/brown, and the wings seem to be darker and maybe iridescent at the tips. They are chubby/fluffy and have a medium long beak.

Thank you!!!

Welcome to the sight, Alex (that's an interesting last name, by the way). Although the description doesn't quite fit, the behavior sounds like European Starling.

Welcome to Whatbird! They sound like juveniles, probably mockingbirds. Location can help narrow down possibilities.

Ah - sorry, I'm in Portland, OR. The birds are smallish and pretty fluffy/chubby, like the size of a medium orange with a head, tail, and legs.

Okay, that's out of range for mockingbird. Black-billed Magpie seems like a good option.

I usually don't get involved with ID's, especially without a picture, but a Black-billed Magpie would be very, very unusual on the west side of the Cascade Mountains, so I doubt that's it. But.......I got no idea, otherwise.

Life list 263. Latest lifers: Black Swift, Calliope Hummingbird, Yellow-breasted Chat and Veery.
