Monday of this week when Scott got home from work he noticed this Oriole at our Hummingbird feeder. He opened the blinds to get a picture of it and before he new it the Oriole was pecking at the window. He called me at work because he didn't know what to do. I told him he was probable saw his shadow and thought it was another bird. He had mixed up a new batch of nectar to put in the feed because the other was a week old. Once he put the new nectar in the feeder the Oriole stopped pecking at the window. Maybe they are smarter than we think!?!?
