Louis Balboa managed to get a great shot of the bird perched on a pole, and as far as we can tell, the black-on-black leg bands read 9 on top and V on the bottom. We have submitted the info to the USGS Bird Banding Lab and will post any additional info as we receive it. USGS Bird Banding website is here.
If anyone can look up the bands in the meantime, thanks much! (And thanks, Louis, for the photo!)
