I was able to get close to four Black-crowned Night-Heron, Nycticorax nycticorax, one adult and three juveniles recently, while they lounged about, occasionally fishing from a low tree branch. At this time of year the young birds always have a bit of fluff on their beaks, as they develop new feathers.
It was interesting that there seemed to be one prime perch for fishing and the juveniles always seemed to be able to take it away from the adult. I noted this to a friend once and he asked me if I had ever seen hungry teenagers around a dinner table. Good point.
