I’m going to recycle a reply I made to this thread:
I went to Gri Gri Lagoon. There is a mangrove forest there, with a cattle egret nesting colony, but I didn´t know whether there would be nests at this season. As I was walking along the edge of the colony, suddenly, I was transported into a wildlife documentary. There was a black crowned night heron, and I noticed the way it moved as it climbed the tree – almost cat-like – was it stalking a nest? It was. Before my eyes, it snatched an egret chick, by the head. But the chick was heavy and strong, and struggled free. At the end of the struggle, the chick was dangling from a branch by one foot. Of course there was a great to-do among the egrets; and the to-do attracted a yellow crowned night heron and a vulture – opportunists. The chick eventually struggled back onto the branch and perched there, but I did not see it make any attempt to climb back to the nest. And by that time, I did not see either of the two night herons.
