Have to post this one photo of a Chestnut-sided Warbler in full voice.  Went to a park very near  home and found the bushes alive with birds due to the spring migration. It was  mostly Chestnut-sided Warblers with a few Yellow Warblers, Wood Thrushes and Song Sparrows.  The  males seemed totally driven to out-sing one another, and to jump around trying to find their rivals.  Never saw a female, and wonder if the females, as with so many birds, trail the males by a few weeks.  Anyone know about that?

Perhaps someone can tell me why this seems humorous.  I did not know they could open their beak so wide, but something makes me think he is just a loud mouth doing some bragging.

Appreciate any comments.
