Location: Glen Cove Waterfront Park, Vallejo, CA. There's a small brook that runs through the park that drains to the Carquinez Strait. A small tree fell over the brook, and under the shelter of its branches is running water that's a favorite birdbath. I've photographed american robin, red winged blackbird, yellow rumped warbler, and sparrows. I feel like a peeping tom, sometimes. Lighting is hard, as its dark under the shrub.
Earlier today I took the following shots. I thought I had lesser goldfinches, but when I cropped the pictures the last one threw me off. The beak, for one ... Your help will be greatly appreciated.
#1 lesser goldfinches?

#2 male lesser goldfinch?

#3 - ???? yellow-rumped warbler ?????
