It's not going well

 The Tree Swallows are at normal rate. There are at least three nests with 2-3 eggs. The nests will have 6-7 eggs. The Bluebirds however have not made successful nests. The only pair that I spotted last week lost their three eggs to the wren next door. They are now looking at this box, but no new nest was made.

That was on the South side. The North side has no Bluebird nests.
