The
Sinaloa Wren is a bird of western Mexico, primarily inhabitating tropical
deciduous forest clearings and edges. The bird was unknown in the
United States until 2008. In August of 2008, one was found in Santa
Cruz County in Arizona. A second bird was found in Huachua Canyon in
Arizona the following spring. There are some indications the species
has been expanding its range northward in Mexico, with known populations
only 40 miles south of the U.S. border, so future sightings may be expected.
Note the species was formerly known as the "Bar-vented Wren".
Habitat
Sinaloa Wrens are found in tropical
deciduous forest, most often in and around forest edges and forest clearings
and nearby undergrowth and shrubbery.
Diet
Diet is composed primarily of insects.
Behavior
The species often forages in vegetation,
and can be easier to hear than to see. Foraging is often done alone,
although sometimes in pairs or very small loose groups. Most foraging
is done low in vegetation, relatively close to the ground.
Nesting
Like other wren species, the Sinaloa Wren
male often builds multiple nests in order to attract a female.
