This species was once considered an annual vagrant during the late spring in the Pribilofs, however its occurrence has steadily declined in recent years and sightings have become much less regular, though it is still more regular than many other species of Asian vagrants. Many of the records for this species include individuals that were […]
An extremely rare vagrant that has been found at all seasons, this species could arrive at almost any time. It is perhaps more likely to arrive in summer or fall and more likely than Common Cuckoo (Cuculus canorus) during the late summer and fall seasons. It is difficult to separate from Common Cuckoo and great […]
An extremely rare vagrant, this remains the only record from the state of Alaska. While the timing (mid-late June) is typical for vagrant swifts in the Pribilofs, the likelihood of a second record seems exceedingly low. […]
The only Pribilof record (St. Paul Island), and the only summer record from North America, falls outside of the “traditional” period of vagrancy for this species in western Alaska with all previous records coming from the end of May or very early June. As such, late May is perhaps the more likely time for a […]
Another species of swift that has been found during mid-late June, the three St. Paul Island records represent half of the confirmed sightings in North America. Considering their close timing, this period of the summer is likely the best chance for future sightings. […]
The most common swift species in western Alaska, though still a very rare vagrant, it has been found across a much larger time frame from mid-June to mid-September. The best times to look for this species are during mid-late June in the spring/early summer and during late August on their fall migration. […]
The only hummingbird species to breed in Alaska, the two records constitute the only Bering Sea records for this species, which breeds no closer than south-coastal Alaska. The timing of records fit well with the pattern of dispersal in hummingbirds and late summer or very early fall remain the most likely time for a vagrant […]
The first Pribilof, Alaska, and North American record was found in late October, which matches the pattern of vagrant coots and gallinules in Alaska, and specifically in the Bering Sea region. This one record involves a bird initially seen on St. George Island, which was subsequently found on St. Paul Island (or remarkably a second […]
There is a single record of this species from late October, which is the first record of this species from the Bering Sea. Its occurrence fits the pattern of vagrancy in this species within Alaska, similar to that of Hooded Merganser (Lophodytes cucullatus). […]
A regular, though sporadic, spring migrant through the Pribilofs, this species is decidedly less common at other seasons. Most records are from mid-May to early June, with a peak of abundance during the second half of May. Very rarely birds will linger into, or arrive during, the summer, with a handful of records into late […]
