Like many other birds, the Pine Creeping Warbler constructs its
nest of different materials, nay even makes it of a different form, in the
Southern and Eastern States. In the Carolinas, for instance, it is usually
placed among the dangling fibres of the Spanish moss, with less work-
manship and less care, than in the Jerseys, the State of New York, or
that of Maine. In the latter, as well as in Massachusetts, where it breeds
about the middle of June, it places its nest at a great height, sometimes
fifty feet, attaching it to the twigs of a forked branch. Here the nest is
small, thin but compact, composed of the slender stems of dried grasses
mixed with coarse fibrous roots and the exuvia9 of caterpillars or other in-
sects, and lined with the hair of the deer, moose, racoon, or other animals,
delicate fibrous roots, wool, and feathers. The eggs, which are from four
to six, have a very light sea-green tint, all over sprinkled with small pale
reddish-brown dots, of which there is a thicker circle near the larger end.
In these districts, it seldom breeds more than once in the season, whereas
in the Carolinas, Georgia, and the Floridas, where it is a constant resi-
dent, it usually has two, sometimes three, broods in the year, and its eggs
are deposited on the first days of April, fully a month earlier than in the
State above mentioned.
Its flight is short, and exhibits undulating curves of considerable ele- gance. It migrates entirely by day, flying from tree to tree, and seldom making a longer flight than is necessary for crossing a river. The song is monotonous, consisting at times merely of a continued tremulous sound, which may be represented by the letters Trr—rr-rr-rr. During the love season, this is changed into a more distinct sound, resembling- toe, twe, te, te, te, tee. It sings at all hours of the day, even in the heat of summer noon, when the woodland songsters are usually silent.
It is a hardy bird, seldom abandoning the most northern of the Eastern States until the middle of October. I saw none beyond the Pro- vince of New Brunswick, and Professor MacCu'lloch of Pictou had not observed it in Nova Scotia. In Newfoundland and Labrador I did not see a single individual.
I have placed a pair of these birds on a branch of their favourite pine; but the colouring of the male is not so briUiant as it is in spring and summer, the individual represented having been drawn in Louisiana in the winter, where, as well as in the Carolinas, the Floridas, and all the Southern Districts, it is a constant resident.
