P. De Benedicts 1965 Arenaria interpres 17 June Barrow, Alaska - Flare like "chewit chewit chewit," and on the ground a series of notes "cut cut cut" after breed or migration. They are not as social the other shorebirds, being more spread out over the tundra. Also Saw one chase a Sandplover feeding nearby in a trough area. 18 June Two swift seen in the Barrow area, fly about, one giving the "cut cut cut" call but no marked display other than a slower than usual wingbeat 19 June There appeared to be more birds in the area between S and S. Salt hogoon; heard the usual assortment of calls and saw several feeding in saltus low, wet areas throwing mud aside and apparently taking, food from below the surface. Close inspection of areas where they had been feeding showed that they were ripping up the snowy cover to the tundra to get to the food below. 20 June There were more birds present in this above area than yesterday and some are clearly social. All birds seen feeding were in wet low situations and feed in turnstone fashion. 21 June A flock of 8 was seen flying in the W over S part of S. Salt hogoon and it continued on our M. Salt hogoon out of sight. Scattered birds on the west, around yesterday were almost entirely absent; and heard few vocalizations.
