Observation details

Large terns with noticeable shaggy black crests. Longish, thinish bills, yellow orange to tip. Compared to Caspian Tern the birds were not as bulky, and bill was thinner and paler than a red-billed Caspian shows; also birds did not exhibit extensive dusky underprimaries that a Caspian features. Adult bird had white forehead and forecrown, black line through eye extending back to rear part of crown and crest. Adult upperwing had blackish edges to outer primaries, underwing predominantly paler throughout. Younger bird had more dark in upperwing and some in primary edges of underwing. Forehead and crown of younger bird were more dusky in front of black crest. 3 photos of younger bird taken from Rye Beach attached with apologies for poor quality due to distance and heat shimmer. Photos of adult bird taken from Read were too poor to include here.
