Charles River, Charles River Peninsula, Needham, MA |
Bluebirds and tree swallows have been around for a week or two but have just started defending particular boxes. So nest box checking starts now!

Eastern Bluebird couple, Box 5 |
I think it's fair to say we have evidence of bluebird nesting behavior at box 5.

Eastern Bluebird female, Box 5 |
When I checked the box earlier in the week it appeared as if they were building on top of a tree swallow nest. We'll see if the tree swallows (or house sparrows) let them keep it. (This has been a contentious box in the past).

Tree Swallow, Box 8 |
Tree swallows are on all the remaining boxes
 |
Tree Swallows, Box 14 |
including the house sparrow favorite, box 14 (though the swallows successfully claimed it last year).
 |
Tree Swallows, Box 15 |
and even "extra hole" box 15, which I had basically written off this year. I wonder if and when they will notice its unsuitability?

Pine Warbler, Charles River Peninsula, Needham, MA |
And warbler migration season has officially commenced. Lots of yellow-rumped warblers, ruby-crowned kinglets, and pine warblers singing from the canopy today.
