Roseate in the lower right, other two birds are Common Terns
Observation details
One adult roosting with common terns on rocks at the end of the trail, allowing extensive direct comparison. The bill was mostly black ,although the proximal quarter was orange. I gather that that is not atypical for this date. It had a long white tail extending notably past the wing tips. In the nearby common terns, the tail did not reach the wingtips. It was notably whiter on the belly than the common terns that were much grayer on the belly. The much less extensive black in the primaries was evident on the folded wing. There may have been a first summer bird in the area as well, but I only saw it in flight and didn’t get to study it well, but was struck by how white the upper wing surface was, especially in the secondaries and coverts.
