A large robin wave has entered the southern part of my village. They have covered the lawns and fields in the area. Intense singing is occurring from what sounds like scores of robins at once. I also observed aggressive behavior within the flock. Robins are chasing each other and making the peek calls. It has been raining and the worms have come out. The winds have finally shifted from the south, blowing the lid wide open for robin advancement.
