Well, he doesn't look really happy, but his wing patches are mostly covered so he's not feeling too hostile. I remember, years ago, wandering through a swamp with a pair of chest waders looking for an active blackbird nest. The parents weren't listening to my assurances that I wasn't going to harm their chicks and I actually got a pair of wings in the back of the head for my trouble. Made two images and moved on... no permanent damage to anyone involved.
Mike.
