    Details: Rare this far north. Observed for 10 min by two observers through 8x binoculars at a range of 40-60 meters. Medium large tern - observed directly adjacent to Heerman's Gulls (who were harassing the terns). The terns were just slightly smaller than the gulls in length, but had significantly shorter wingspans. Molting into basic plumage. Significant white forehead with black ear patch and black hindneck. Longish, orange bill; not blocky and red like nearby Caspian terns. Light gray wings, with darkish primaries and dusky primary coverts. Underwing significantly white, with some black tips on the underside of the primaries (trailing edge of the wing tips). Calls unlike nearby Caspians. Calls higher pitched than Caspians, two-syllables: kerr-rik (matches calls on Sibley app). No photos.
