One of the West Park cormorants was sitting at the top of their usual tree. A second bird flew in and tried to land on the nearby branch.
The first bird squawked violently, and lashed out with several bites aimed at the newcomer. After a short period, the second bird flew off again. It looked like some of the feathers on its wing might have been damaged or disarranged.
It circled the lake three times, then came in to land again. This time, it settled a little lower in the tree, perhaps a yard lower that the other bird.
Incumbent seemed to be getting ready for another go, then acceped the other’s presence now it was in a more subordinate position.
