Wow. Bluebirds and Killdeers in winter is something I have never seen.
cool. I heard once that evolution has birds coming back early or not leaving to gain better breeding territory. I have seen Robbin’s doing it my whole life.
Bluebirds are one of the first to return. I don’t think the same is true of killdeer. Most years I have seen Bluebirds by March 1st. I haven’t seen one yet, but thought I heard one a week ago.
