Bluebirds vs Swallows

Apr 24, 2018   It looks like a pair of Eastern Bluebirds have made a choice.  They have spent the day protecting the two bluebird houses near the Buckeye and the Weather Station.  He spends a lot of time sitting in the tree and she is in and out of one of the houses--frequently with her head sticking out which prevents a Tree Swallow from entering.  It seems to be working.  I think the protection of the nearby tree helps but who knows?

I wonder if this is the same male bluebird that I saw early in March that prompted us to get out there and clean out the houses--but then I did not see another for over a month.    LRL
