Golden-crowned Kinglet

The Golden-crowned Kinglet is a common summer resident in the Canadian Zone, but throughout the rest of New York and New England a winter visitant only, arriving in late September and leaving by the end of April. In northern New England it is not common in winter. Kinglets are often associated in winter with Chickadees; if, therefore, the sharp tsit of the Chickadee is heard in fall or winter, it is well to follow the sound and, when the Chickadees appear, to keep eye and ear alert for any of their traveling companions. Often the Kinglets travel alone, searching restlessly the twigs of trees and hedges, following perhaps a well-marked course through plantations and woodland, and calling to each other with a thin sharp see-see-see. If the birds are in thick evergreens, spruces or cedars, it is very hard to get even a glimpse of them, but in leafless apple-trees, a favorite resort, they display their brightly marked heads and quick, restless ways. They do not cling to a twig upside down like the Chickadees, but occasionally one flutters for an instant before the desired morsel and picks it off. Their numbers vary from winter to winter, and even in the course of a single season there seems often to be a fluctuation. In April their numbers increase, as the birds that have wintered to the southward pass through as migrants. In March and April the males continue the lisping note, put more and more power into it, and then by a descending trill fall, as it were, from the height to which they have scaled, — this is the song of the Golden-crowned Kinglet. The lisp of the Chickadee, the screep of the Brown Creeper, and the see-see-see of the Kinglet all have a strong resemblance. The last two are sharper and more finely drawn out, the Kinglet’s is quickly repeated, while the Creeper’s is one long

In summer the Kinglets keep almost wholly in the spruces, and are thus even more inconspicuous than in winter; their song and call-notes, however, make their presence known. Their call is now often longer and still more like that of the Creeper. The young, which are found in little companies in late July and August, lack the head-markings of the adult; they may be recognized by their small size and by their lisping notes, identical with those of their parents.
