The
Golden-crowned Warbler is a widespread species of warmer locations in both
North and South America, extending from Mexico and Central America southward
through Brazil. In the United States they are a vagrant, with a number
of sightings in far southern Texas, and one in eastern New Mexico.
There are a number of sub-species present throughout their range, with the
possibility that birds currently classed as Golden-crowned Warblers may
indeed comprise multiple individual species.
Habitat: Found in humid, tropical and sub-tropical
forests, including mature forest, second-growth forest, and sometimes
heavily managed lands such as coffee plantations or other tree plantations.
They can also sometimes be found in thickets and undergrowth of more open
woodlands, or in brush with nearby forest land.
Diet: Feeds mostly on insects, but they will also
take fruits, berries, and seeds on occasion.
Behavior: Very active foragers, Golden-crowned
Warblers typically occurs in the forest understory. They are somewhat
gregarious, often forming small loose foraging groups that may include other
small insectivorous species.
Nesting: The nest of a Golden-crowned Warbler is a
dome-shaped structure built on the ground, typically in a location that is
semi-protected by a clump of vegetation, a stump, or other protective cover.
The nest is built of grasses, roots, and other fibrous plant material.
The female lays between 2 and 4 eggs, which she alone incubates. The
eggs hatch after about 12 days.
Song: The song of a Golden-crowned Warbler is a
series of rich warbling, with variation between different populations within
their broad range. They also have a sharp tik note and a
scolding chatter.
Migration: Golden-crowned Warblers are considered
permanent residents throughout their normal range.
Feeders: Will occasionally come to feeder
setups for nectar (sugar-water), fruits, and nuts.
Conservation Status: Populations overall appear to
be in decline. However, they are still relatively common in many parts
of their range, and cover a wide geographic area.
The
IUCN lists the Golden-crowned Warbler as a species of "Least Concern".
