A hawk came flying over the other morning and Martins came from out of no where and started attacking him. Then more Martins came up--probably from a big Martin colony near me. Probably 15-20 Martins fighting off the hawk. They were pecking at his wings and everything. They chased him right out of here.
I suspected that Dennis' Martins were keeping check on my pair over here by themselves. I think they proved that theory. About three or four Martins will come over here almost every day and check out the Martin house and fly around with my pair. They also sit on the Martin rig and talk things over.
