50 Million Cowbirds

Okay, well maybe five dozen is more like it, but that is still a lot of cowbirds in our backyard. Over the last month their numbers have been climbing at our morning junk bird convention. I took these pictures this morning.

Elly thinks it must have been a good year for them. I guess they leave their eggs in the nests of other birds. Ornery critters. I wonder what factors make them more or less successful in any given year? Or why they are congregating around here this year? We've noticed that the numbers of particular birds rise and fall. A few years ago we had about 6 dozen house finches with us throughout the winter. The last couple of winters, though, there have been only half a dozen or so.

They certainly have the mourning doves outnumbered these days.
