P. DeBenedictis 1965 harens hyperboreus 24 June Barrow, Alaska - a group of over 82 was present in Central Marsh in the early afternoon, including the 1st 2nd year birds I have yet seen, although the majority (barely) were adults. On two occasions two were seen to attack Pomarine Jaegers carrying lemmings and succeeded in getting the lemming from the jaeger. The jaegers fought back but were not successful. According to Dr. Pitelka, it is highly unusual for the gulls to outnumber the jaegers.

Many are clearly non-breeders as evidenced by most of the inner primaries. 25 June The large group still present in Central Marsh 26 June Virtually gone from the Marsh Now. 27 June About 500 on Barrowville dump, very noisy and more immature involved than I had thought. Found a dead 1st year bird near the FAA Tower. 28 June Found Two dead immatures in the area across Voth Creek from the VOTH area, a 1st year bird eaten by jaegers and a 3rd year bird which appeared to have been shot. Birds flying over the area seem to pass for the most part unchallenged. 30 June One small group out in Central Marsh. 2 July A group of 125±25 were present in the Center of Holmer's
