Backyard Birds

I need more practice with my new camera so I have been taking photos of the birds as they come to eat at the feeder. These were taken from inside the house. Actually we get more of a variety than just cardinals and bluejays..... wrens, doves and brown thrashers. I don't know why the mockingbirds don't feed at our feeder. I have enjoyed trying different settings and lenses to take photos of these unsuspecting birds.
