The
Eurasian Blackbird, also known as the Common Blackbird in its native Europe
and Asia, is a common thrush with very basic black plumage, with a obvious
orange eye-ring and bill. They are found throughout most of Europe and
parts of southern Asia. In North America, they are known only from a
handful of sightings in southeastern Canada. There is some question as
to whether the birds sighted in North America were truly wild vagrants, or
if they were escapees from captivity. However, the species has
expanded its range in recent decades. Once very rare vagrants in
Iceland, they now regularly are found as breeding birds there, and vagrants
have also shown up in Greenland. As with several other species of European
songbirds, they have also been introduced in Australia and New Zealand, and
now have established populations throughout both countries.
Habitat: Found in a very wide variety of habitats
including forests and woodlands, agricultural landscapes, and urban parks
and suburbs.
Diet: Omnivorous, feeding heavily on insects and
other small invertebrates such as earthworms, snails, and slugs. They
will also feed on fruits and berries if available.
Behavior: Foraging often occurs on the ground,
with birds walking and hopping about in search of insects and other
invertebrates. They will also feed in the forest canopy or in shrubby
vegetation when fruit is available.
Nesting: The female builds a nest of grasses,
leaves, rootlets, and other vegetation, bound together with mud. The
nest is usually placed in a dense thicket or bush, but as the species is
well accustomed to a human presence, they will also sometime build the nest
on a human structure. The female lays 2 to 5 eggs, and she alone
incubates them. The young hatch after about 13 days, and are fed by
both parents. The young leave the nest about 2 weeks after hatching.
In many locations Eurasian Blackbird pairs will raise 2 or even 3 broods in
a given year.
Song: The song is a series of warbled phrases that
may vary between local populations. They also have a variety of calls.
Migration: Considered permanent residents in much
of their range, particularly in western Europe and southern parts of their
range. Eurasian populations further north typically do migrate
southward or westward for the winter, with some birds overwitnering as far
away as northern Africa or far southern reaches of Asia.
Similar Species:
Adult males that may be seen as vagrants in North America are unlikely to be
confused with other species. The brownish females may be potentially
confused with other native North American blackbird species.
Conservation Status: Eurasian Blackbird
populations are strong overall, and may be increasing. They are found
over a very broad geographic area, and are common in parts of their range.
The IUCN lists the
Eurasian Blackbird as a species of "Least Concern".
