Swainson’s Thrush

Catharus ustulatus

The rarest of the Catharus thrushes found in the Pribilofs, this species is most often found during the first half of September coinciding with the peak of the similar, but more common, Gray-cheeked Thrush (Catharus minimus). The records that lie outside of the first half of September during the fall come from late August and mid-late September, which still falls well within the normal migration windows for this genus in the Pribilofs. The lone October record is quite late for this species in the region and state. The single spring record is an unexpected outlier, with late May or early June likely representing the best period in this season with which to expect a future record.
