I help the Virginia Bluebird Society by checking a 1.5 mile bluebird trail of 10 boxes. On the first box check of this season today, I sadly discovered two recently deceased tree swallows (one per box) in two of our bluebird boxes. We had recently had a several day cold snap--I assume they were unable to either stay warm enough and/or find enough insects.

I did find a almost completed tree swallow nest in a third box that had a tree swallow nearby. The bluebird society leaves all native bird species' nests in the boxes until that nesting is done.

We do remove and destroy any non-native species' nests (which are usually English Sparrows who will kill bluebirds and their young in order to take over the boxes.)
