Black-winged Stilt
There is a single spring record from mid-May in the Pribilofs from St. George Island. This species has been sighted in North America only a few times in western Alaska, with all records during the spring in May and early June. […]

Mallard
A regular, albeit sparse, migrant in the Pribilof Islands, which could be seen at almost any time of the year but is most regular in the spring between May 5th and June 5th and again in the fall from mid-September into October. The beginning of spring migration for this species typically falls outside of the […]
Northern Pintail
This species has typically already arrived before the first birder coverage commences in the spring with moderate to large numbers present by the beginning of May. Migrant numbers usually peak in mid-to-late May, with a decline in migrants by June 10th and standard breeding numbers usually present from mid-June on. The exact migratory pattern is […]
Green-winged Teal
Early migrants have typically arrived prior to the first birder coverage in early May with small-to-moderate numbers arriving during mid-late April. Timing of migrant and peak movements is clouded in the Pribilofs due to summer residents; however, predictably the largest spring numbers would be found in mid-late May with a decline in daily numbers until […]
Canvasback
This species has been found only very rarely in spring during mid-to-late May and in the fall during early-mid October. This pattern is typical of this waterfowl genus (Aythya) and it is likely that this is when future records will be found. As most records involve single individuals, they are often found in the company […]
Common Pochard
A very rare spring migrant that is encountered on average every few years, though this species has a pattern of showing up for several years in a row and then not being seen again for an extended period of time. The best time to see this species is mid-May, with most records from May 10th-25th […]
Ring-necked Duck
This species has mostly been found as a spring vagrant or summer wanderer with over 10 records during that period, beginning in the late 1970s. The majority of records are from mid-late May, which is to be expected, and often involves a pair of birds. There are two early summer records (both in 2009) with […]
Tufted Duck
This is a nearly annual visitor during the spring with sightings nearly annual since 2000 and more than 50 records for the Pribilofs since the 1910s, with many of them involving more than one individual over an extended period time. They are occasionally found earlier in the season, though the best time to see this […]
Greater Scaup
A common spring migrant and perhaps the most common diving duck that is a passage migrant. This species can be found regularly during May and June while birds likely begin appearing during April in most years and birds linger into the summer season regularly as well. Overall numbers typically peak in mid-late May, though substantial […]
Lesser Scaup
The first Pribilof (and Bering Sea) record came as recently as 1961, though this species has proven to be a semi-annual vagrant in recent springs. Most records come from the second half of May with scattered spring records into mid-June. A few spring arrivals have lingered into July while an occasional summer wanderer has been […]
