This is the bird that first caught my attention, a white throated sparrow, leukic. I think that's the term. It has white feathers where there should be pigmented feathers. Behavior normal. Lots of energy. Non-stop eating.
A normal white throated sparrow. There were about 50 in the garden.
The downy must have been very hungry, because it was pecking by my face. No concern for the camera presence.
