Surprisingly, the 277th casualty on this project was just the 4th Orange-crowned Warbler, which is a common migrant here in central OK. This one was an ASY male with fat = 1. I first spotted him from about 80m away.
Check out this guy’s truncated rectrices, blunt-tipped primary coverts, and his pointed primaries:
The most exciting thing about him, though, is that this old guy actually had an orange crown. I’ve never seen one so orange, which makes me wonder if this fellow was closer to 10 years old than merely “ASY”. It is so sad to see such a vibrant, mature, elder statesman of a warbler cut down by something so stupid as a window. He deserved better.
