This little guy and I go round and round every spring. He thinks he's going to nest in one of my purple martin gourds. Well, he does end up using one, but one that is hung away from the others. However, this year the tree swallow may have won anyway, because I have no martins interested in staying around. My dad cleaned up the area around the retention pond where his gourds are- about a quarter mile away, and his colony is full (they all went there.) I'm still hoping for a late comer- but just today I saw a starling in one of the gourds. I shall have to switch out to all starling resistant holes. I wish the martins would appreciate what I do for them, and come nest at my place!
