I could tell something was up again this morning. No sign of birds at the feeder, or anywhere else in my yard. I looked up at the Red Maple and there she was - the Sharp-shinned Hawk. She's become a regular this week. I suspect I'll be seeing her off and on until it's time to migrate.
As I watched, she flew from the tree to the feeder pole.
How do I know this is an adult female? While both sexes are similar in plumage, females are considerably bigger than males. Adults have red eyes. Immatures have brown to yellow eyes.
