Species: Golden-crowned Kinglet
Regulus satrapa
Description:
This tiny songbird,
hardly larger than a hummingbird, is very active; it habitually
flicks its wings nervously. It can be found all over North America,
breeding in the Boreal range from Alaska and across Canada, and
wintering in the southern United States and just into the tip of
Mexico. But here in Vancouver, and indeed down along the west coast,
it can be found year-round.
Golden-crowned Kinglets in the west, compared to eastern
populations, tend to be smaller but with longer bills, are slightly
greener on the upper parts with the white supercilium extending back
to the nape.
Identification:
The Golden-crowned
Kinglet is 3.5-4” in length and weighs a mere 6g. The bird is
usually a dull-olive green to greyish above and a pale grey to white
underneath. It has rounded wings and short tail with a little notch.
The bill is small, and the legs are black with yellow feet; the
wings are dark, edged in bright green with white wing bars and a
dark bar across the base of the secondaries.
Adult Male: These birds have a very conspicuously striped
face: a black eyeline, a definitive white supercilium, and another
black stripe on either side of the bright, yellow crown. The orange
feathers in the crown identify mature males.
Adult Female: The adult female is identical in plumage to the
male, but her crest is entirely yellow.
Juvenile: The juvenile lacks any gold in the crown, as it is
a dull-olive; its back may also have a bit of brown in it.
Similar Species: The Ruby-crowned Kinglet has a plain face apart
from a white eye-ring. Both the Black-capped and Chestnut-backed
Chickadee have an obvious black bib and solid cap.
Behavior: Golden-crowned Kinglets tend to flock with other
small birds when foraging, and one will often find them among
chickadees, creepers, and nuthatches. Hunting small insects, insect
eggs and spiders, they glean their food off branches and leaves,
hovering at the tip or hanging upside down! Generally these birds
tend to forage higher in the canopy in summer and lower in winter
and during migration.
Habitat: Dense and mature coniferous forest is the preferred
habitat for Golden-crowned Kinglets, particularly during the
breeding season, but for migration and winter, mixed woodlands will
also do just fine.
Information:
The Golden-crowned
Kinglet nest is a globular cup, half-hanging from outer branches; it
is made of spider silk, moss, lichen, twigs, and leaves. The female
incubates around 8-9 eggs (cream white with dark spots) for about 2
weeks.
Interestingly, these birds can raise 2 broods per season; after the
first young have fledged, the female starts straight away on her
second clutch.
The thin and high-pitched voice of this kinglet, begins with a
shrill “tsee tsee tsee” before tumbling down into a chickadee-like
babble.
Conservation
Status:
Recently, these
birds have been slowly expanding their breeding range into the
northeastern US. And at the moment, the Golden-crowned Kinglet has a
status of Least Concern. Some studies show western populations in
decline and eastern ones rising, but more information is needed. (It
can in fact be difficult to monitor nesting, as the nest is usually
quite high up!)
