25 June, Barrow, Alaska A nest was discovered at 0930 with three green eggs blotched with brown. It was located in the middle of some weasel tracks. At 1615 the nest contained four eggs. It is located about 150 yards east of the AACS. There was no wing display given when the nest was found or when it was rewilded. 5 July, Barrow, Alaska. The above nest was checked today, and the bird was still incubating despite the disturbance she her bed with all the traffic. When flushed, she did a type of mouse run which differs from that I saw in the sandpipers. She crowded, but held wings in position and just barely ruffled her back feather. This posture was only used for a short distance (6 or 8 feet) from the nest, at which she assumed her normal position.
