PINE WARBLER. 
{Sylvia pinus , Lath. Wilson, iii. p. 25. pi. 19. fig. 4. Phil. Muse- 
um, No. 7312.) 
Sp. Charact. — Bright olive-yellow, tinged with green; beneath 
yellow, clouded with obscure spots ; vent white ; wings with 2 
whitish bands, and with the tail dusky brown ; 2 lateral tail- 
feathers partly white ; lores not black. — Female greyish brown, 
tinged with olive green on the back ; beneath pale yellow on the 
breast. — Young dusky olive above, yellowish obscure white be- 
low. 
This common species, to the commencement of win- 
ter, inhabits all parts of the United States, and probably 
extends its northern migrations to the forests of New- 
foundland. They arrive in Pennsylvania at the close of 
March and beginning of April, and soon after are seen 
in all parts of New England, amidst the pine and juniper 
forests, in which they principally reside. Both the old 
and young remain with us till nearly the close of Octo- 
ber ; stragglers have even been seen in mid-winter in the 
latitude of 43 degrees. # In winter they rove through 
the pine forests and barrens of the Southern States in 
companies of 20 to 50 or more, alighting at times on the 
trunks of the trees, and attentively searching them for 
lurking larvae, but are most frequently employed in cap- 
turing the small insects which infest the opening buds of 
the pine, around which they may be seen perpetually 
hovering, springing, or creeping, with restless activity ; 
in this way they proceed, from time to time, foraging 
through the forest ; occasionally, also, they alight on 
the ground in quest of worms and grubs of various kinds* 
or dart irregularly after hovering flies, almost in the 
manner of the Flycatchers. In these states they are by 
far the most numerous of all the Warblers. In the month
