Childs 1951 Baird Sandpiper Erolia bairdii June 10 Point Barrow Alaska We have seen them daily since arrival. While collecting on the first ridge, one was taken and a flock of 5 flew by. They appear to have a buzzing flight song June 11 They were common between camp and the barrel drop. The & took had an egg in oviduct + 4 MT follicles - and a slight brood patch. June 12 2030. One was seen in a song flight south of camp twice within a few minutes June 13 The song flight was heard several times, on the mid ridge and it is entirely different from that of the Rectal Sand. The bird flies high in the air giving a bronzer note constantly, quivering its wings as if it was flying hard against the wind, and then drops. June 14 1600 Frank & I watched one in a display flight of the south end of LW in which the diameter of the area was at least a third of miles. It chased another that appeared to be a neighboring individual some distance. The wing beat is fast while giving a rattling call and then glides giving the breath note. June 17 Rose found a nest, clutch of 4, one day wide. Nest lined with grass, no feathers. June 18 Both Gil & Rose checked nest today & thought it decent June 28 Nest behind lab has no eggs now. They were there 2 days ago
