A walk around Branton Ponds this a.m. with 50% ice cover saw the waterbirds packed in together. This obviously led to 2 of the Canada Goose flock having a noisy & violent confrontation. The more submissive participant being loathe to leave the flock used surprising tactics. When attacked it would dive below the water, and fully submerged pop up 10 yards away, much to the consternation of the attacker. Meanwhile the 17 Goldeneye oblivious to the commotion continued their display.
