R.B. Hamilton 1965 Sterna paradisaea Barrow, Alaska June 25 Birds were seen flying over either singly or in pairs. In the light which they were seen they appeared quite greyish. The translucent quality of the primaries was observed and seems to be a good field mark. One bird was seen feeding in Central Mosh. It descended slowly to the water surface and seemed to pick something from it with its bill. July 5 One Arctic Tern was observed flying over the Brittler area. July 6 Five birds of this species were observed flying over. July 8 Two birds were observed flying over the Brittler Area. July 9 One bird was observed feeding in the Arctic ocean. July 11 One bird was observed feeding along the shore, of a lake to the NW of Lake Ikorowite. July 13 One bird was observed flying over. July 15 Four birds were observed flying over Central Mosh. July 16 Four Arctic Terns were observed feeding in Velschlage slough. July 21 Two birds of this species were observed over Central Mosh. July 25 Two pairs were observed in a small Sabine Gull colony. It was felt that these birds were nesting. Two chicks were found that perhaps belonged to this species. They were located on a mound and the nest cup was obvious. Arctic Terns were flying overhead giving distress calls. Two single birds were observed over the tundra. In good light the character mentioned by Retusser of being able to see through the wings is quite visible.
