Anyone notice birds acting strangely lately? I just had a robin flapping at my window - kept acting like it was trying to get inside my house. This went on for about 20 minutes. Couldn't let it in though - I have an indoor cat. Never had this happen before. I mean - this bird was right on the window and windowsill flopping at my window. It would sit on my patio, then come running up to the window (not flying - it was on both feet) poking at the window with it's beak and head and flapping its wings at the window. My patio comes right up to the outside window. It just about drove my cat nuts.
