Long-billed Dowitcher

Long-billed Dowitchers are accidental in spring and can be common in fall on the Pribilof Islands. The scant few spring records come from May 18 _ June 2. Southbound adults can begin to appear as early as July 10, and juveniles begin appearing as early as August 20. The two fall surveys have shown that this species can occur in large numbers (a high count of 113 on Sep. 8, 2003) through at least the end of the first week in October. Long-billed Dowitchers are trans-Beringian migrants, with an extensive breeding range in northern Russia. Juveniles seem to regularly use the Pribilofs as a refueling stop on their way to their new-world wintering grounds. This is in sharp contrast to Short-billed Dowitcher, which breeds in central Alaska and occurs primarily as a spring overshoot on the Pribilofs. Breeding plumaged adult Long-billed Dowitchers are best separated fromcaurinusShort-billed Dowitchers by their entirely reddish underparts, barred breast and flanks, and white tipped scapular feathers. Juvenile birds should be identified by their largely unmarked gray tertial and scapular feathers, gray face and by their calls. Feeding flocks of Long-billed Dowitchers will often give a short high-pitchedkeekcall. The call of Short-billed Dowitcher is a mellowtu-tu-tusomewhat reminiscent of the calls of a yellowlegs.
