J P Myers 1976 Journal Prudhoe Bay, W. Slope, Alaska 26 June (cont'd) Sterna paradisaea - seen regularly in low numbers foraging in wetlands. No sign of breeders. Nyctea scandiaca - seen twice near West Dock. → Acanthinip - heard flying overhead on 2 occasions, both times near Buffy Pingo. Calcarius lapponicus - abundant, widespread through most habitats, apparently limited only by the need for a dry nesting site. Sometimes I wonder if even that is necessary. OB still singing, but not regularly. A few flocking by 88. → Mots monitored by Steve Johnson near VE began hatching 21 June. Preying nutria obvious throughout my stay. I stumbled over at least 10 neat all with 4+ young. Suffering tremendous fox predation (see Johnson). Plectrophenax nivalis - blessedly limited to local sites around camps. Very restricted, not seen otherwise. Corvus corax - 1 individual seen on 3 separate occasions. Well that's it. Nothing unusual, just good, clean birds at Prudhoe. [illegible] I have appended vegetation description to today's journal, taken from work by D.S. Walker + P.J. Webster, INSTAAR. My transect units are all described in rough + qualitative terms using W+W's major Prudhoe vegetation classes. In general my impression is that habitat separation is clearer here than at Barrow, perhaps in part due to the more better defined separation between upland tundra and lowland areas. The finer scale of habitat interdigitation which pervades Barrow does not rule the Prudhoe regime. Instead there are a few large areas varying greatly in overall composition (this is an exaggerated simplification, but the trend is there).
