P. De Bevedich's 1965 Calidris alpinae 26 June Barrow, Alaska - there was more aerial display over Holmes's Marsh this afternoon than I have heard for some time. A bird seemed quite nervous about our approach and I saw it flying as if off a nest which Dr. Pitelka found. I was in tall (3-4") NEST 1 dead grass and contained 4 eggs, located about 35 feet from a jaegle's nest. 27 June Saw 3-4 birds with wing molt and found 1 nest in the Oostl area containing 4 eggs. The bird was obviously nervous about our approach and stood in an alert posture when approached. In contrast to Bairds & Semipals they do not fly well when going near the nest but run in a rather crouched, almost mouse like posture for as much as 100-200 feet before going to the nest, which is approached very indirectly. The bird sat once as if incubating under well away from the nest. The nest was out in rather sparse gross, well cupped over by the grassy cup; kliiip but no sure that the incubating bird was beginning its molt. Birds were fairly noisy in the Oostl area but few and far between everywhere else. 28 June Saw a nest with 3 eggs in Micanet Marsh, the nest was in grassy level ground and fairly well concealed. The bird flew off giving a distraction display quite like that of P. pusillus (g.v.) and gave a similar, high pitched call, which at one time attracted a Pectoral, a Semipal & a Snow Bunting. Saw 4-5 Melting birds and found them to be generally
