The
Piratic Flycatcher is a well-named species. They don't build their own
nests, instead raiding nests of other birds, even displacing birds that are
actively nesting and destroying their eggs and/or young. They are
normally found from Mexico through South America, and are but rare vagrants
to the United States. They are mostly known from sightings in Texas
and New Mexico.
Habitat: Found in semi-open country and open
woodland, including forest clearings, forest edges, open woodland, and open
areas with scattered groves of trees.
Diet: Mostly feeds on insects during the summer
breeding season. Will also feed on small fruits and berries,
particularly in winter.
Behavior: Forages by observing from a perch, and
flying out to capture insects, either in mid-air, or by gleaning them from
the vegetation surface.
Nesting: Doesn't build a nest of its own, but
instead, appropriates the nest of another bird. If a nest of
interest is already in use, the Piratic Flycatcher will harass the
nesting birds until they leave, and will destroy any eggs and displace
any young in the nest. The female Piratic Flycatcher then lays 2
or 3 eggs. She alone incubates the eggs. The young typically
fledge about 18 days after hatching.
Song: Most common vocalization is a repeated
whee-whee.
Migration: Breeds in Mexico, through Central
America and into South America. Birds breeding in Mexico and Central
America migrate to South America for the winter.
Similar Species:
For birds potentially encountered in the United States, most similar with
the Sulphur-bellied
Flycatcher.
Conservation Status: Overall populations may be
decreasing, but they are still found over a wide geographic area and are
relatively common in parts of their range.
The IUCN lists the
Piratic Flycatcher as a species of "Least Concern".
