Not that I have favorites, but AMLE (Amelie) is my new favorite junco. Most juncos get a bit dejected by the end of the banding process (don’t worry—as soon as they realize we’re letting them go, they perk up), but she was sharp the entire time. When it was time to take pictures, she glared daggers at us.
She also kept a sharp eye on me.
If you think her bill looks long, you’re right: she has an unusually long bill. She also has a surprising amount of white in her tail for a female junco. Usually females only have white on their outermost two tail feathers, but she has white on her third-outermost feathers as well.
