A recent addition to the avifauna of North America, this species has proved to be a semi-regular vagrant to the Pribilofs in the fall during the 2010s. Recent records have mostly been clustered during the final week of August, which is likely the best time to look for this species in the islands, though an […]
Category: Leaf Warblers (Phylloscopidae)
Common Chiffchaff
Much like the Willow Warbler (Phylloscopus trochilus), this species was not recorded until very recently in North America, though it has since been found a number of times with a single Pribilof record (St. Paul Island) coming in early September, which fits the general pattern of vagrant Phylloscopus warblers in the islands. This species should […]
Wood Warbler
A long-distance migrant that breeds no closer to North America than central Russia, this species is a very rare vagrant to Alaska with two of the six records coming from St. Paul Island. All records of this species in Alaska have been from mid-September to early October, with the very end of September or first […]
Dusky Warbler
An annual vagrant to western Alaska, this species is especially rare in the Pribilofs. A skulking species that could be under-recorded due to detection problems in the islands, there are only a few records from St. Paul Island. The single spring record falls in line with the only other spring Phylloscopus records from the islands […]
Yellow-browed Warbler
A very rare fall vagrant to western Alaska, this species has been recorded a few times on St. Paul Island at that season. Records from mid-September fall within the standard period for Phylloscopus vagrants to the islands, while the early October record is on the late side, though as a hardier species this timing is […]
Arctic Warbler
The most common Old World warbler in the Pribilofs, and the only Phylloscopus species to breed in North America, it is best looked for during the fall when it is nearly annual. However, a couple spring records from mid-June and a scattering of summer records from late June to late July indicate that it can […]
Kamchatka Leaf Warbler
This is a difficult species to assess in the Pribilofs. A regular vagrant to the western Aleutians during the spring where the similar Arctic Warbler (Phylloscopus borealis) has not been recorded, there is only one conclusively documented record from the Pribilofs (St. Paul Island). However, some late fall records of the aforementioned species from late […]
