Pine Siskins persist.
Audubon Field Guide: Pine Siskin
Although it is patterned like a sparrow, its shape, actions, and callnotes all reveal that this bird is really a goldfinch in disguise.
Pine Siskins feeding with American Goldfinches during Winter Storm Juno.
After nesting in the conifer woods, Pine Siskins move out into semi-open country, where they roam in twittering flocks. They often descend on fields of thistles or wild sunflowers, where they cling to the dried flower heads, eating seeds. In winter they sometimes invade southward in big numbers, with flocks coming to feeders along with American Goldfinches.
Courtship and formation of pairs may begin in winter flocks; male displays by flying in circle above female, with wings and tail spread widely, while singing.
Very erratic in its winter occurrence, coming south in huge numbers some years, very scarce in others. After big invasion winters, a few may remain to nest south of normal range.
That would be nice.
