My bluebirds are building their second nest and I as always supply mealworms. Well, I have this persistent Bluejay who keeps coming in the yard and eating all of the mealworms. Mr. Blue sits atop my house watching him and I don't know how to get rid of him. He is definitely not going to give Mr. and Mrs. Blue a good feeling with laying eggs in their box. I've moved the feeders away from the box ... what else can I do? Thanks!
