P. DeBenedictis: obs 1965 Larus hyperboreus 2 July Barrow, Alaska - first time and was not bothered by jaegers at all for all intents and purposes although the whole group was up when they were 1st noticed. Gulls fly over the Central Bluff-Beach Bridge being noticed only occasionally. A group of 75±25 (prob. +) has been at the N end of Fresh Lagoon for the past 2-3 days. Both groups contain fair numbers of subadult birds, and many are beginners, the primary molt. 4 July no groups seen today. 5 July a large group near lines JTA-73 towards the Barrow Dump. 6 July no groups seen. 7 July do.; a few flying over the area and about 10 on Fresh Lagoon in the A.M., and now spilled towards the VOTH area from the Barrow Dump. 11 July Two probable breeders seen on the ice of a small lake W of Kroavik and a few more seen in flight. 19 July A number seen flying east along the lead, the largest group 10, in the evening. 20 July [illegible] on the ice behind the lab, and few seen flying along the shore in the evening. 22 July A group of 10-15 on the ridge behind S Salt Lagoon contained 1 small & 2 well dark mantled dark-tailed immatures, which had typical Glaucous bill bills (pinkish with black tip). They are badly discolored and I suspect that they are the "nelsoni" phase of this species rather than Heining gulls.
