Mourning Warbler
I saw this Mourning Warbler yesterday. When you look closely, you can see a faint dark bib like on the adult male. I don’t know if it was an adult or an immature. All I know is that he was very agitated, chipping loudly and moving around. I don’t know if they were begging calls or what was going on. There may have been a nest nearby, or fledglings hiding in the bushes.

This is what a male Mourning Warbler looked like earlier this summer.
