This is the first time I have intentionally shot a bird butt. I do it accidently all the time. I've gotten enough birdie behind pics to do a bird butt series! :0)
This is a Yellow-rumped Warbler. Birdwatchers have nicknamed it Butter-butt, because of the bright yellow spot on its behind that looks like a pat of butter.
You can see a frontal shot in my main album today. :0)
He is very cute.
