“…The mean hatching date of eider nests on Egg Island was 6 days later than in 1971. Similar phenological delays were recorded in the Prudhoe area in 1972 for tundranesting waterbirds (Bergman et al 1977) and insects (MacLean 1975). In "late" summers fewer nests are initiated, smaller clutch sizes prevail (Barry 1960), and renesting is less likely than during "normal" summers.…”

“…Peak phalarope numbers in mid-June (about 1.5 birds/km?) in the study area coincided with the start of nesting inland in 1972 (Bergman et al 1977). The small number of phalaropes seen in the study area in late June (< 0.1 bird/ km?)…”

“…The small number of phalaropes seen in the study area in late June (< 0.1 bird/ km?) corresponded to the departure of females from the breeding grounds (Bergman et al 1977). In early August young phalaropes flew to the coast, where they congregated in nearshore waters (about 8 birds/km2; they apparently are also found at least 80 km out to sea at this time (Frame 1973).…”

The number and distribution of birds near a barrier island west of Prudhoe Bay, Alaska, were recorded during the phenologically "late" summer of 1972. During eastward (spring) migration, most birds were restricted toa small area of open water in the nearby river delta. Although numerous eiders (Somateria sp.) fed and rested in the island area during spring migration, few did so in late summer, when Oldsquaws (Clangula hyemalis) and Red Phalaropes ( Phalaropus fulicarius) congregated near the island.

“…The study area included coastal plain habitats along the Chukchi and Beaufort seacoasts between the Colville River and the western edge of Kasegaluk Lagoon, including NPR-A (Figure 1). Wetland habitats ranging from shallow Carex ponds to deep Arctophila lakes, often set in basin wetland complexes, dominate the region, especially east of Barrow (see Bergman et al 1977 for detailed wetland descriptions). Habitats surveyed included barrier islands, river deltas, saltmarshes, mudflats, sparsely vegetated dunes, and wet tundra.…”

We describe the current status of nesting by Lesser Snow Geese (Chen caerulescens caerulescens) and Brant (Branta bernicla nigricans) on the western Arctic Coastal Plain of Alaska. We conducted aerial surveys along Alaska's Beaufort and Chukchi seacoasts in 1991-1998 to determine the current distribution and abundance of these two colonially nesting goose species and to monitor their status at selected colonies. Areas of optimal habitat were surveyed, so we doubt that any large colonies of either Snow Geese or Brant were missed. We obtained the first specific size and location information for two colonies of Snow Geese on the Kukpowruk and Ikpikpuk river deltas, which combined were occupied annually by a total of approximately 100 pairs. Snow Geese nested irregularly within the study area at 15 other locations that accounted for no more than 13 nests in any year. Museum records indicated that Snow Geese have nested near or at some of these sites since at least the 1930s. Brant were recorded nesting at 135 locations in the study area. The combined total number of nests (estimated by adding the highest recorded number of nests for all sites) was over 1070 (1-53 nests/location). The majority of these nests were located east of Barrow and within 10 km of the coast. Most nests were located on islets in shallow lakes and basin wetland complexes, but three colonies were located on deltaic islands. Historical information on Brant nesting locations in the region is limited.
