The
Wood Warbler is a "leaf warbler" species of the Old World. They are found as
breeding birds throughout much of temperature Europe, into far western Asia,
while they overwinter in tropical Africa. In North America they are
known from multiple sightings on islands and coastlines of Alaska.
Habitat: Found in deciduous woodlands and forests
Diet: Feeds on insects and spiders. They
will also sometimes feed on fruits and berries.
Behavior: Actively forages by hobbing and flitting
through foliage, either in the forest canopy or closer to the ground.
They feed by either gleaning insects directly from vegetation, or by
capturing insects in short flights.
Nesting: The nest of a Wood Warbler is placed on
the ground, or close to the ground in a shrub. It is a dome-shaped
structure with a side entrance, built of grasses, moss, rootlets, leaves,
and other vegetative material. The female lays between 5 and 7 eggs, and she
alone incubates them. The eggs hatch after about 13 days, and both
parents help to feed the young. Young fledge about 2 weeks after
hatching.
Song: The song is a high-pitched trilling that
continually increases in tempo. The trilling song is often followed by
a lower-pitchd series of 4 or 5 soft, monotonous notes.
Migration: Strongly migratory, Wood Warblers breed
in Europe and far western Asia, but move to tropical portions of Africa for
the winter.
Similar Species:
In their Old World range, may be confused with other Phylloscopus
(leaf warbler) species. They are the largest of the Phylloscopus
species seen in their normal range in Europe.
Conservation Status: Population trends appear to
be declining in the European part of their range. However, overall
they are still widespread and common in parts of their range.
The IUCN lists the
Wood Warbler as a species of "Least Concern".
