1. Cade 1958 Bt Calcaris lapponicus 19-20 June Barrow, Alaska Seen rather uncommonly over the tundra this year - not so abundant as last year. The first run of 6 transects yielded only 4 individuals. See Brock's notes. On the 19th I found a nest situated just to the left of T6-4.0, and it contained 5 eggs which were placed in a very exposed nest in a crevice on the side of a little mound of moss - . 2.5-26 June Coal Mine - Meade River - abundant all over the tundra - commonest bird and more abundant than it is at Barrow this year. A nest with one fledgling was found 1/4 mi S of camp. Nest at base of Ericophorum turrock, lined with ptarmigan feathers. Young: 5 toes full length feathers. Primaries 1 1/2 inch long in sheath, tail feathers 1/2" long. 7 June a recently fledged young was seen today on the airstrip. 8 June A recently fledged young, which I caught and released, was seen on tussock-heath tundra between the village and T7-28. Adult 9 gave distraction display. 9 June Two recently fledged but flying juveniles seen down river from the village today.
