I live in Atlanta, GA, USA. There is a Brown Thrasher in my yard, and it looks very sick. See pic here - https://imgur.com/a/DdgIT29 and video here https://www.youtube.com/watch?v=OYt6OV2PEk4&feature=youtu.be As you can see, it has two very swollen something on the sides of its face, and cannot close its beak. It comes to my deck to try to eat suet pellets, but is having a hard time. Does anyone know what this is? I feel terrible for it.
