Calidris fuscicollis June 12 Barrow Alaska - Two White-rumped Sandpipers were seen on Beach Ridge near where the gasline crosses it. These birds flew when approached to within 30 yds. They flew to the NE June 13 Three birds were observed feeding in the area W of Family Lagoon. One bird was approached to within about 5 yds without flying. On the ground the best field mark seems to be two large reddish-brown patches on the back, one on each side of the midline. June 15 One bird was observed feeding in the Vault Area. One bird was observed feeding in the Barrel area. June 17 At least three pair of these birds were seen in the Britton Area. They could be approached within about 20 ft. without flying. They generally were not too close together and perhaps their occurrence in two's was accidental. A bird, presumably a ? , was seen displaying in front of another bird (maybe a female - since it did not react). In this display the displaying bird stood facing the other bird. The tail was cocked vertically so the white rump patch was visible. The wings were held out to the side of the body and curved slightly. The head was directed frontwards and little sidling movements were made with the feet. A very low "pooit!" was heard three times. [illegible] After this a wing up was given in about 30 seconds another wing up was given. The white-rumped was observed chasing a Semipalmated Sanderling being chased by a Dunlin.
