[Bristol-Birds] nesting Cliff Swallows

I just returned from a walk at Domtar Park along Riverport Road in Kingsport
where hundreds of Cliff Swallows nest each summer. While there I took a
quick look and was surprised to find at least 18 still active nests. Birds
were actively carrying food to young that were visible at nest entrances.
Seems a bit late for these birds to still have young in the nest.  What say
ye?
