Eastern Yellow Wagtail (Motacilla tschutschensis)

The Eastern Yellow Wagtail and the Western Yellow Wagtail (not found in North America) were recently split from the former "Yellow Wagtail" (Motacilla flava), although some authorities continue to maintain the old classification of one Yellow Wagtail species. Most Eastern Yellow Wagtails are found as breeding birds in northern Asia, but there are also breeding birds in northern and western Alaska. Long-distance migrants, Eastern Yellow Wagtails migrate to southeast Asia or the Australia region for the winter. As with other wagtail species, Eastern Yellow Wagtails do indeed frequently wag their tail as they walk along the ground, foraging for insects and other food items.

Habitat

In the Alaska summer breeding range, they are found on tundra, in areas with thickets of dwarf willow or dwarf birch.

Diet

Feeds mostly on insects and spiders, as well as small mollusks such as snails, and other invertebrates such as worms. Also may feed on berries and seeds.

Behavior

Feeds by walking on the ground, often making fast runs to capture insects when they are spotted. They will also sometimes catch flying insects in flight, or hover briefly while gleaning insects from vegetation.

Nesting

The nest of an Eastern Yellow Wagtail is a cup of grasses, weeds, mosses, and lichens, lined with feathers or animal hair. The nest is built on the ground, usually under a small shrub or next to a clump of grass. The female usually lays 4 or 5 eggs, and both parents help to incubate them. When the eggs hatch, both parents help to raise the young. The young leave the nest after about 2 weeks.

Song

Song of the Eastern Yellow Wagtail is a series of repeated short notes

Migration

Long-distance migrant, with birds found in Alaska normally wintering in Australia and southeast Asia.

Conservation Status

Populations may be decreasing, but they are still found over a wide geographic area and are relatively common in some areas. The IUCN lists the Yellow Wagtail as a species of "Least Concern".
