Yay. My tree swallows are so aggressive this year and plentiful and are taking over even my bluebirds box. I don’t think the bluebirds can take it anymor. I might lose them on the firsr. Eat.
Tammy, sure hope you can keep one box for the blues – keep trying, don’t give up on them!
P.S. I believe my mama began incubating yesterday or today, as there are 5 eggs and I did watch her go in this morning. I haven’t had TRES back for a couple of years, ever since they had a failure with 5 babies dying inside the box about 4 days before fledging.
