The only sighting of this species is from St. Paul Island in the early fall (late August/early September). Future records are highly unlikely, and if they do occur the best time is unknown, though presumably it is fall. There remain only two records of this species for North America and at the time of those […]
This species has only been found approximately nine times in the Pribilofs during the fall season from mid-August to mid-September, which coincides with their retreat from much of their summer breeding range in Alaska. This is likely the only period in which this species will be found on the islands in the future. […]
The only record from the Pribilofs is from early May. Of the Alaskan records, there are a grouping of sightings during May and another grouping of sightings in the fall during late September and October. Further records are likely to appear during one of these periods. […]
This is a common to abundant, winter resident that can be found regularly in the spring and fall, while a few linger into the summer in some years. In most years, the bulk of wintering birds have left the Pribilofs by May 25th with smaller numbers continuing until June 10th and only a few lingering […]
This species has been found very sparingly on its passage between Alaska and its wintering grounds in the south Pacific. The majority of records come from the springtime where they are spread over a large period of time though the second half of May, which is likely the most productive time to locate this species […]
The single spring record from late May to early June is one of few from the entire state and fits well with the pattern of occurrence of other tern species in the Pribilofs, as well as the other records of this species from Alaska. […]
A nearly annual spring migrant, which is best found in late spring from June 1st-15th, though it can be found beginning in mid-May and occurs occasionally into late June and July. There have been only three fall records of this species with two in mid-August, the typical migration period for other tern species, and one […]
A regular, albeit uncommon, spring migrant that is best looked for from May 20th-June 10th with a peak from May 15th-25th at that season. However, this species is found more regularly later in the year. While it can be seen on occasion during late spring and early summer, the peak time of occurrence is from […]
The least common of the four regularly occurring loon species in the Pribilofs, this species has been seen with increasing frequency in recent years though it is still considered less-than-annual in the islands. Sightings of this species are widely scattered from May to October, with the most records coming during late spring/early summer and late […]
The rarest loon species in the Pribilofs with only about a dozen records, this species is most often seen during the month of June, especially mid-month, though based on the few records it could be seen at nearly any time of the year. A regular migrant into the west-central Aleutians and nesting in northwestern Alaska, […]
