Maker 1959 Larus hyperboreus May 17 Barrow, Alaska. Gull arrived in numbers on morning of May 16. Are now about dump and not at all on tundra. None have been seen on the tundra yet May 22 Pitegea River. Few have been about along river since we arrived. Sometimes only one 2, or 3 flying along river. This morning there was a flock of a dozen or more along shore downstream from camp. May 23 Few of these cruise up and down the river - seen occasionally in 2's or 3's or singly May 25 Saw two flying along river this afternoon. May 26 Saw surprisingly few in walk about river delta - perhaps a total of 5 from delta to camp. May 27 Saw 4, 3 juveniles, white, + one adult. All in delta or along river. June 3 Pair on S. end Skravik. Pouncing about a particular area. Two on edge of Elson Lagoon. One flying along Elson + one near gas well. June 12 Two in evening along river. Seem scarcer here than formerly.
