The Tara (White-fronted Tern, Sterna striata) is commonly seen in large flocks and this one was no exception.

I was on the south side of the Waikanae River mouth, where there was a flock of several hundred Tara resting on the sand. Among them must have been young because the entire time we were there, there was a constant stream of birds flying well down the beach and returning with a fish.
