Two of my four nest boxes have been claimed.
I'm always pleased to see the Bluebirds sitting near a nestbox. This male was helping build a nice grass nest inside.
Wednesday there were three eggs. Yesterday four. Still four this morning, so I think they decided quadruplets was enough for the first nesting.
If all goes well, hatching will be May 19.
On the other side of the field, Tree Swallows have finished their nest and are aggressively guarding the box. No eggs yet but probably tomorrow.
