This is a female Great Crested Flycatcher with her beak full of nesting material. She would then place it just right on her nest while her mate sang away - their voice is a mix between a frog and a cricket, but I bet it sounds beautiful to her. We have named them Sonny & Cher, they are nesting in our backyard. I hope to be able to capture them from nest building to when their babies fledge.
