Blue Jays
Cardinals, sparrows... and the dark guy in the front middle is a brown-headed cowbird. I had never noticed one up close before. We looked it up on whatbird.com and found out what he was.
Then I think he must have told his fifty closest friends about our feeders. They were all over the place-- and on the other feeder too, but I scared them off before I could get that picture taken.
The finch are some of my favorites to watch. We have several American Goldfinch and House Finch who stop and visit.
I guess you could say it's the number off birds eating that makes all the food disappear and not that one bird eats so much... but whatever the case, they sure do go through the birdseed!
