Until
1993, the Pacific Golden-Plover and the
American Golden-Plover were
considered one species. However, despite the very similar appearance between
the two species, breeding habitat, breeding calls, and migration patterns
are different, and it is thought the two species rarely, if ever,
interbreed, despite being found in the same general region of western Alaska
in the summer. They also breed in northeastern Asia.
Habitat: Found on Alaskan tundra during the summer
breeding season. During migration and in winter, they can be found in
a variety of open habitats.
Diet: During the summer breeding season, primarily
feeds on insects, as well as berries and seeds. In migration and in
winter, feeds heavily on small crustaceans and molluscs, as well as insects.
Behavior: Feeds by running on the ground, visually
identifying food items and plucking them up with the bill when found.
They are gregarious, and typically forage in small to moderately sized
flocks of up to 100 birds or more.
Nesting: The nest of the Pacific Golden-Plover is
a small depression on the ground, lined with lichens, moss, dry grass, or
other plant material. Both parents incubate the eggs. Both parents
also typically help tend to the young, but occasionally the female will
leave and the male alone will raise the young. Just after hatching,
the fledglings must find their own food (typically insects), while the
parents defend them from danger.
Song: Song of the Pacific Golden-Plover, given
during flight displays, is a plantive whistling, tee chee-eee.
Will also give a simple two-toned flight call, with a stronger second
syllable.
Migration: Highly migratory. Pacific
Golden-Plovers breed in western Alaska. In the fall, most birds move
to islands in the Pacific, with significant numbers migrating all the way to
New Zealand or Australia. Small numbers of Pacific Golden-Plovers may
also winter on the U.S. West Coast.
Conservation Status: There are currently no
perceived major threats to Pacific Golden-Plover populations, and the IUCN
currently lists Pacific Golden-Plovers as a species of "Least Concern".
