Chickadees were going crazy!
Not a great photo as it was taken through the windshield. I knew it would fly as soon as I opened the door and that's exactly what happened. Light morph red-tailed hawk??
This is certainly a first for me! I highly suspect that maybe someone is putting food colouring in the birdbath?
Photo 1 shows one parent in nest after an exchange with the other parent. It is the last in the sequence. Photos 2-12 show the sequence of the change at the nest. The number 2 arrives, and they gradually change places, and number one flies away.
