A765, a male Caspian tern, was banded and fitted with a satellite tag on 02 April, 2015 at Crescent Island. He and his satellite tagged mate (F367) were observed nesting at East Sand Island starting in May of 2015, and they successfully raised and fledged young that breeding season.

In 2016, A765 was a late arrival onto the breeding grounds. He did not arrive back to the Columbia River estuary until 08 June. He stayed in the vicinity of East Sand Island through 23 June then began moving southward again. He did not overlap with his mate from the previous year (F367) very much at East Sand Island and may not have attempted to breed this year.
