Ok, so nothing near as detailed as what I got with the red-winged blackbirds, but I forgot that we did have some Northern Flickers nesting in a tree near our house. Their nest cavity was probably 40 feet up, so this was the best I could do to capture the changing of the guard as one flicker returned to the nest and the other took off. I wish I could have gotten the one in flight in focus, but it happened so quick, I didn't have a chance to change the focal point.
