They are nature's garbage men! I live near a park with mature trees that is sandwiched at the intersection of two busy roads. The turkey vultures settle in on a garage roof across from the park a block from the intersection and just have a buffet! They are magnificent.

I have those that hang out in my front yard,they like to sit on top of the hummingbird feeder.I didn't know they were good fly catchers though. Kathi

That's a male so-called "English house sparrow"(Passer domesticus), an invasive species that is neither English nor a true sparrow, but an African weaver finch. These prolific birds are very messy and destroy nests of many cavity-nesting native bird species in order to build their own bulky nests in their places.

Looks like a domestic pigeon that probably escaped from its owner or didn't find it's way home. Head structure doesn't look like a Homing pigeon.
