What robin behaviors does this observer describe for this wave of robin arrivals? Read, then look and listen!
"A large robin wave has entered the southern part of my village. They have covered the lawns and fields in the area. Robins are chasing each other and making the peek calls. I also saw aggressive behavior within the flock. 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." Dolgeville, NY, April 1
