觀察細節

Tern flying north with another Sterna. Fairly agile light Tern with a dark cap. Red bill base, dark wedge in primaries, grayish underneath, and fairly thick dark trailing edge on the underside of the primaries that also extended some to the leading edge. Managed to get some semi-decent digiscopes of this individual after it looped and flew around between the point and Eva before heading back south.
