Recorded annually in small numbers, this species is most likely to be seen from late May to early June. Spring migrants can arrive as early as mid- May (peak is in late May), with regular records through June 10th and sporadic records the entire month of June and into the early summer during July. Summer records of early southbound individuals occur mostly in late July or early August, with fall migrants in general not being as common, nor as predictable, with scattered records through late September though the most records come from the end of August. Both American (hudsonicus) and Asian (variegatus) birds are regular to the islands, occurring in about equal numbers, perhaps with Asian birds being slightly more regular since the 1990s.
