Hi, everyone -- I'm trying to identify the bird in the attached photo, taken a couple of weeks ago near Sand Springs, Oklahoma (a few miles west of Tulsa). Merlin says it's an indigo bunting; I've never seen one. He did appear to favor perching at the top of trees, which is an identifier of indigo buntings. I apologize for the poor-quality photo; he wouldn't let me get very close. Thanks, in advance, for your help!
