I was wondering about something similar too. I've noticed over the years that in general birds will pick up singing again around early July. I'm thinking that some species may have a second brood in early to mid summer.
I was reading in Birds of Missouri that Sedge Wrens move into the state in late July and early August and begin nesting then. I wonder where those birds are coming from?
