This is perhaps the earliest passage migrant to arrive in the Pribilofs each spring with the first migrants likely appearing during March or April each year with peak numbers probably having moved through by mid-May. This species is normally still present into the tourist season, which begins in May, though most individuals are gone by […]
Most sightings of this species in the Pribilofs are assumed to be migrants passing from Alaska to northeast Russia (or vice versa) where they breed on Wrangell Island, though the majority of this population passes across the Bering Strait to the north of the Pribilofs. As such it is only a rare migrant with semi-annual […]
This species can be expected each spring in small numbers during May and early June with a peak occurrence period from May 15th to June 1st. It is a regular, though scarce, migrant which is often found in very small groups or mixed with other goose species. It is very rarely found outside of the […]
The one late spring/early summer record of this species was entirely unexpected given timing and the species overall abundance. The global population of this goose has plummeted in recent years and as such it was not a likely option for arrival in the islands on rarity alone. The timing of this record likely indicates an […]
This large Asian goose is found very rarely with semi-regular sightings during the spring over the past 25 years and a single summer record. It has been identified nine times in the Pribilofs with eight spring records and one summer record. All records except one have been from the 1990s or later when coverage was […]
A vagrant goose which is not expected, though somewhat regular during the spring. It has occurred in the islands every few years since the 1990s, with nearly all of the known records being from the second half of May. This is considered to be the more expected bean-goose within Alaska and does outnumber its congener […]
The second most common goose species during the spring, this species becomes the most regular migrant goose species during fall migration in the Pribilofs. It is most common in the spring from May 15th to June 10th with a peak of occurrence around June 1st. Fall migrants are usually first found during early September and […]
This species has skyrocketed in abundance during recent years thanks to the very successful recovery of the Aleutian-breeding subspecies since the 1990s. It is a common migrant in the spring and into the summer in most years, though there remain distinctly fewer fall records, which are on the increase as well. The other Alaskan-breeding subspecies […]
This species has only been reported five times from the islands with all records being of individuals that arrived between mid-May and mid-June. The identification of “Lesser” Canada Goose from Cackling Goose (Branta hutchinsii), especially ssp. taverneri, can be quite difficult and is not well understood by many. Caution should be used when identifying unusual […]
There are two Pribilof records of this species, an early northbound individual during late April in the winter season and a hypothetical record during the spring in early May. This is one of the earliest migrants to return to Alaska each spring and as such it is likely to be a very early migrant when […]
