In addition to the Eastern Bluebirds that are nesting in our backyard this pair of House Finches (Carpodacus mexicanus) are regular visitors to our backyard as well. The female, shown below, was shot using Donna's Rebel T2i (I've been shooting it a lot lately) and my EF 400 f/5.6L lens. Exposure was 1/180th at f/5.6, ISO 400. She really enjoys splashing around in the bird bath and feeding on sunflower seeds.
Below is the male House Finch. I really like his red coloring. This guy can eat sunflower seeds faster than anything I've ever seen. He's also very vocal so I always know when he's around. For some reason though he likes to try and drink out of the hummingbird feeder. He'll fly over to it and try to stick his beak into one of the tubes but he can't get anything out. This picture taken with my 7D and EF 400 lens. Exposure was 1/250th @ f/5.6, ISO 400.
