Tree swallows have started nesting. Out of the ten boxes I'm monitoring at CRP this year, six already have full nests.

Traditional conflict magnet, box 5, features a robust house sparrow nest. If you look closely at the photo you'll see a dead tree swallow incorporated into the nesting material.

I pulled out five warm eggs. They were sacrificed to the Charles River.
