The
Oriental Turtle-Dove, also sometimes called the Rufous Turtle-Dove, is a
species normally found in Siberia and other parts of Eastern Asia. In
North America, they are extremely rare vagrants. Multiple sightings have
occurred in the western Aleutian Islands and on islands in the Bering Sea
west of the Alaska coast. These are almost certainly true vagrants,
wild birds that have naturally reached these areas from breeding locations
in eastern Asia. Multiple sightings have also occurred on Vancouver
Island in far southwestern Canada. The origin of these birds may be in
question, and may represent escaped cage birds. However, given the
migratory nature of the Oriental Turtle-Dove and its tendency to sometimes
wander far from its normal range, the Vancouver sightings may also represent
naturally occurring, vagrant birds.
Habitat: Found in a very wide variety of habitats,
particularly during migration and in the winter months. During the summer
breeding season, they are primarily found in forested areas. These
same habitats may be used in migration and in winter as well, but they are
also often found in open habitats, particularly agricultural environments
with available seeds and grains. They are also very well adapted to a human
presence and are often found in urban and suburban settings.
Diet: Feeds heavily on seeds and grains.
They have a bit of a reputation as a species that will negatively impact
agricultural fields, especially rice and wheat, but also soybeans and other
crops. They will also feed on herbs and forbs, and fresh young shoots
of some plants.
Behavior: Forages on the ground, walking around
and picking up seeds and other food items from the surface of the ground.
Nesting: The nest of a Oriental Turtle-Dove is a
platform of sticks, lined with leaves and grasses, and placed in a tree or
shrub. The female lays 2 eggs. The male usually incubates the
eggs during the day, while the female incubates them in the evening and at
night. The eggs hatch after about 2 weeks, and both parents help to
feed and protect them. The young fledge from the nest after 15-18
days. Multiple broods are often raised each breeding season.
Song: Oriental Turtle-Doves are often quite vocal,
issuing very frequent low cooing sounds.
Migration: In its native eastern Asia, southern
populations may be year-round residents. However, those found in the
northern part of its range are strongly migratory and move southward for the
winter.
Similar Species:
They are similar in overall structure and size to several other dove and
pigeon species, but the unique plumage makes them unlikely to be confused
with any other species (if seen well) other than their close relative that
European Turtle Dove. Both
of these Turtle-Dove species are extremely rare visitors to North America.
However, the Oriental Turtle-Dove has only been seen on the far western edge
of North America. The European Turtle-Dove has only been seen on the
far eastern edge of North America. Given the native range of these two
species and past sightings in North America, the location of a sighting is
thus a reliable method of distinguishing which of the two species a rare
North American sighting may be. In terms of appearance, the European
Turtle-dove is noticeably smaller, and tends to have a pinker blush on the
breast.
Conservation Status: Oriental Turtle-Doves are
found across a very broad geographic area, are common in parts of their
range, and overall populations are considered stable.
The IUCN thus lists
the Oriental Turtle-Dove as a species of "Least Concern".
