I don't see the doves actually on the birdfeeder that much. They're just too heavy. They usually stay on the ground waiting for the seeds to drop. Maybe that's what happened to the birdfeeder that I found on the ground.
Amazing how you were able to catch this. Like you say, doves generally do not go to the feeders, and you even caught his lovely wing. Exciting capture to say the least and a fav.
