The most common breeding species in the Pribilof Islands, it is an abundant resident from the spring through the fall. Individuals begin to return to the islands in late March or early April with substantial numbers present by mid-late April. Many thousands are present by the beginning of May, with breeding commencing during the first […]
An arctic species that is likely found annually in the Pribilofs, generally in association with winter sea ice, though there are only sporadic reports of this species. This is one of only a few species that is more likely to be found in winter, which is why there are only about 10 local records, with […]
A year-round resident of the Pribilof Islands, though there is no evidence that it breeds locally, this species can easily be found at most times of the year. It is most common in spring, during the second half of May, as the birds move between their wintering grounds at sea and the mainland or other […]
There are only six known occurrences of this species in the Pribilofs, all in the spring during late May or early June except for a single fall record in late September. However, there is no reason to believe this species isn’t possible at any time during spring, summer, or fall with recent records in Alaska […]
This species has been recorded approximately 20 times in the Pribilofs with those records scattered across much of the year. The majority are from the spring (mid-May to early June), with a couple of summer records, several fall records, and a single winter record. This pattern of occurrence likely involves several modes of occurrence for […]
This species has been recorded a few times in the Pribilofs, in spring and in the fall. While the records are undocumented, this species is undoubtedly annual around the Pribilofs considering that it breeds to the south and winters to the north along the Bering Sea ice pack and further records should occur, mostly likely […]
This species can be found year-round in the Pribilofs (when open water exists), though it is most reliable in early spring from May to early June. After mid-June this species begins nesting and sightings become much less regular as they are rarely found in near shore waters during daylight hours. By mid-late summer sightings are […]
A very rare alcid in the central and northern Bering Sea, this species does not range north of the Aleutians regularly and as such is extremely rare around the Pribilofs. This species prefers warmer water and therefore is best looked for in summer and fall, particularly in years with above average sea temperatures, which may […]
An abundant breeding species that is easily found from May through much of August, this species becomes much more difficult to see locally in fall and winter. Large numbers typically begin to return to the islands in late April with the full breeding population present by late May and early June. Nesting occurs in June […]
The most common breeding auklet in the Pribilofs, this species typically arrives at the islands cliffs in mid-late April. They often arrive en masse and are present in the thousands by May, with the peak breeding numbers occurring from late May to early July. The estimated breeding population for St. George Island is 125,000 pairs, […]
