Kingbird. Tammy on a 5DIII. I try to avoid 600mm if possible; 552mm is about as long as I like to go. More reach and less cropping on my 40D might have worked, but it was a pretty gloomy day, and I had to use higher ISO's.
1. @500mm




2. @500mm




3. @552mm




All nice and sharp! Beautiful bird, too.
