Beaver 1967 species account Pectoral Sandpiper 2 Barrow Alaska 14 July (cont.) A short distance on in central March, we came across a flock of all Pectorals (30-50 birds) that is the largest we've seen yet. This is small compared to past years at this time. (Perc.com. - Steve). 15 July P.M. Steve collected 5 Ads. from a flock near ADCS. This flock has been growing in size last few days. It has been mixed, having G. flowers, L.B. Sandpipers on occasional Bairds and today a Carlou sandpiper (scope see for 15 July - C. Sandpiper). 21 July Scattered flocks still around, but not nearly as many birds as earlier.
