This is a normal, though sparse, winter resident that is regularly found during early spring. They become less reliable by the end of May and are rarely encountered after early June with only a few records of lingering summer birds. There are a handful of summer arrivals, most commonly in early July, which is likely due to failed breeding birds that begin to wander. Except for a single late August arrival, they have not been located before early October in the fall with double digit numbers having been recorded by mid-October, while similar numbers carry through the winter season into early spring depending on the extent of the winter pack ice and the amount of ice free water around the islands.
