Tígulþerna - White-winged tern - Chlidonias leucopterus
Adult birds in summer have short red legs and a short black bill (small and stubby, meausuring 22–25 mm from the feathers, decidedly shorter than the head), a black neck (often with a pale gray back) and belly, very dark grey back, with a white rump and light grey (almost white) tail, which often looks 'square' in juveniles. A vagrant in iceland and a new lifer for me no. 163
