觀察細節
Adult breeding-plumaged (full black caps) pair circling and calling fairly high over SE side of lake. Initially heard “kee-rick” calls and noticed both almost overhead heading due E then slowly turning and heading out of sight to N. Medium-sized terns slightly smaller and slimmer than CATE, but not as much as ELTE. Clean upperside of outer primaries and mostly clean undersides with darker grayish tips to outer primaries. Bills an even bright orange throughout and thicker with less obvious droop than ELTE. “Kee-rick” calls also subtly lower-pitched and less screechy than ELTE. Photos.
