PINE WARBLER


Dendroica pinus


Description:

The Pine Warbler primarily feeds on insects, but also consumes large amounts of pine seeds. In fact, the Pine Warbler is the only warbler to feed on large quantities of seeds. This seed-eating tendency often brings them to bird feeders, where they will also eat suet. The Pine Warbler is one of the first warblers to return to the North in spring and also one of the earliest to breed, starting as early as late April or May in the northern most part of its range. As you may have guessed, this bird is so named because of its preference for pines, especially for nesting.


Appearance:

Olive green upperparts. White belly and undertail coverts. Bright yellow throat and breast. Dark, blurry streaks along side of breast. Faint yellowish supercilium. Inconspicuous crescents around the eyes. Two white wingbars. Small, dark bill. Dark legs. Sexes similar. 5 to 6 inches in length.


Habitat:

Open pine forests and open mixed woodlands. Winters in wider range of habitats, including deciduous trees, orchards, lowland thickets, and pines.


Nesting:

3-5 whitish eggs with brown spots; often with a band of spots concentrated near the large end. The eggs are incubated by the female and have a 10? day incubation period. Fledging occurs in 10? days. The nest is a deep cup made from grass, pine needles, twigs, and plant fibers held together with spider web or caterpiller silk. It is lined with fine plant parts, hair, and feathers. The nest is placed high in a pine tree.
