This heron was collecting nesting material at San Diego Safari Park.
This Black Crowned Night Heron was selecting nesting materials at San Diego Safari Park. Although this is a park setting, there are many wild birds that nest there.
This cormorant was doing its mating display behavior, which it was carrying out sitting in an empty nest. Since all of the other nests appeared to have eggs and hatched young, all this displaying may well have been in vane. It did give a good view of this behavior and its blue skin area which is distinctive of breeding readiness.
