The Bluebird of Happiness?

Today, we were visited by four bluebirds, perching in the ash trees outside our front windows. The sky was overcast and bright, which made getting a decent picture difficult, but this one came out ok, enough that you can see what it is.

We were really happy to see the bluebirds. Neither Laurie nor I have seen them here before, so seeing two pairs was really encouraging. We should look at the bluebird boxes at the farm, and possibly replace them if they have gotten old or weatherbeaten. I know we'll need to do double boxes due to the large number of tree swallows at the farm.

I'm not sure we have the best environment for bluebirds, but maybe they'll nest on the far side of the yard and then go eat in the big fields at Cornell.
