Mama barn swallow was sitting on eggs and came to the edge of the nest to check me out. Her colorful collar under her chin does not extend as far as the male's does. And she has more white on her breast. She is slightly less colorful than her mate. She was not alarmed, just curious. You can see tiny claws hooking over the edge of the nest. After looking at me briefly, she returned to the center of the nest and hunkered down again.
