Holy moly! This was quite a surprising bit of action this past weekend. Be sure to scroll down through the series.
I was watching these two herons and they seemed to not be too happy with each other. Suddenly, one launched an attack! They bit at each other in a flurry of feathers and long legs and wings. One emerged the victor, chasing the other off.
It wasn’t until I got home and downloaded the pics that I realized one had actually clamped its beak down on the other’s neck! Crazy fun! I have never seen great blue herons act aggressive toward each other so this was a new behavior to me.
