Bluebirds! Season 7. Episode 2. Nesting begins.

Tree Swallows, Charles River Peninsula, Needham, MA
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.
House sparrow eggs
I pulled out five warm eggs. They were sacrificed to the Charles River.

Tree swallows, Charles River Peninsula, Needham, MA
Some tree swallow love-making but no eggs yet, which is good because it's been damp and wet recently. Other CRP bird news: yellow-rumped warblers, palm warblers, barn swallows.
