06/20/2018 - Tree Swallow entering Mt Bluebird nestbox with six(6) BB nestlings inside. Within seconds, the Tree Swallow exit-ed the nestbox with bird poop in its beak which it dropped in nearby meadow. A little nest cleanup.

Wow, Thats odd, Good photos.
It was nice of them to do a little cleaning up while they were there. 🙂
The swallows always come after the bluebirds have started nesting in our boxes and kick the bluebirds out.
