Common Yellowthroat nest with Cowbird egg
Common Yellowthroat nest hidden among dry leaves 2 ft. above ground level
Free time on a sunny morning... Where to go? I landed in a small county park, and had it all to myself except for abundant singing/nesting/feeding birds, including this male Common Yellowthroat with a beak full of bugs. His nest apparently had young birds in it, but I found another Common Yellowthroat nest containing four eggs, one of them being the egg of the parasitic Brown-headed Cowbird.
