Remsen, J.V. 1972 Curlew Sandpiper male did not rise quite so high nor was so sustained. That of the third male was weakest of the three - not very loud and barely rose on the scale. The female after-flushing made several cruising flights around the area (100ft radius), uttering a very high-pitched twittering while the male gave a low-pitched, very rich "chirrup-chirrup". The area over which the Nest 2 male displayed appeared to be smaller than that of the Nest 1 male but that may be because we were disturbing his nest. 20 June NARL, Barrow, Alaska Mine Fitzgerald found two more Curlew Sandpiper nests within the territories of our previously discovered males' and Dr. Pitella found a third under construction; thus polygamy is a fact in this species 22 June NARL, Barrow, Alaska Nest camera placed on Nest 1 at 1630, Female returned to nest after about 5 minutes of hesitation 23 June NARL, Barrow, Alaska Changed film at 2330. Female not incubating. Dr. Pitella and myself searched in vain for Curlew Sandpipers on Gasline Ridge where he had heard them previously 25 June NARL, Barrow, Alaska Removed nest 1 camera at 0930. Female Curlew displaced (one flash) Dunlin from mound by wings - flashing and moving toward him a few steps. Photographed ♀ and ♂ at 2300, 2♂ giving displays. ♀ chased Pectorals repeatedly near nest,
