This is the Doctor. She's a Mourning Dove.
Do I know this is a She? No, because males and female MD's look the same. I just prefer female doctors, therefore, I'm calling her a she. Logical? Not so much.
Anyhow, she's too big to eat from the feeder, so she gets the seeds that fall to the ground. Which helps keep weeds from growing below the feeder. Thank you, Doctor.
