Nest building
Wood pecking
Hiding in a bush hoping the big critter with a camera won't see me. This is a gray catbird [sometimes called a "black-capped" catbird] He had actually just finished beating the crap out of a rival and was resting.
This guy is a chipping sparrow who hung out on my driveway until a catbird showed up and scared him away. The picture is a bit blurry because I was standing in my kitchen and shooting through a screened window.
And finally, watching the goings-on from a nearby tree was this guy, a "least flycatcher".
