Kinglets
Regulus satrapa
The Golden-crowned Kinglet is a diminutive songbird found throughout much of North America. Despite its small size, it is remarkably hardy, capable of enduring extremely cold temperatures. This active bird often forages high in dense conifer foliage, making it a challenge to observe, though its distinctive calls can help locate it.

Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Adults have a bright yellow crown bordered by black. Males display an orange patch within the yellow crown, especially when agitated. Females have a yellow crown without the orange patch.
A prominent black stripe runs through the eye, contrasted by a thick white eyebrow stripe above it.
Upperparts are olive-gray, with white underparts. Wings feature two white wing bars.
One of North America's smallest passerines, with a rounded body, short tail, and a thin, pointed bill.
02 / A place in the world
Golden-crowned Kinglets primarily inhabit coniferous forests, including boreal and montane spruce-fir forests, often near water. They can also be found in mixed forests, wooded bogs, and conifer plantations. During winter, they may utilize deciduous trees and shrubs.
This species breeds across Canada, the northeastern and western United States, Mexico, and Central America. Its breeding range has expanded into some eastern and southern states due to reforestation. Some populations are permanent residents in coastal and southern regions.
Northern populations are migratory, moving south for winter, though some remain further north than Ruby-crowned Kinglets. Year-round resident populations exist in parts of their range, particularly in coastal areas and the southern United States.
03 / Listen a little closer
Their calls are very high-pitched, thin, and often described as a series of 'tsee' notes. The song is an extended version of these calls, becoming louder and chattering towards the end.
04 / The life behind the feathers
Their diet consists mainly of insects and other small arthropods, including caterpillars, small beetles, gnats, scale insects, and aphids. They also consume insect and spider eggs, and occasionally tree sap, fruit, and seeds.
These kinglets are highly active foragers, hopping quickly among branches, primarily in conifers. They often glean prey from foliage and bark, frequently hanging upside down from twig tips. They may also make short flights to catch insects in the air.
The female builds a deep, hanging cup nest of moss, lichens, bark strips, and spiderwebs, lined with soft materials like feathers. Nests are typically placed high in conifers, 2-18 meters (6-60 feet) above ground, attached to hanging twigs near the trunk. Females incubate 5-11 eggs for about 14-15 days.
Males defend nesting territories with song and may display by leaning forward with crown feathers raised and wings/tail flicking. Outside the breeding season, they often join mixed-species foraging flocks with chickadees, nuthatches, and creepers. They may huddle together in dense conifer foliage to conserve heat during cold nights.
One more reason to pay attention
Golden-crowned Kinglets can survive nighttime temperatures below -40°F, partly due to their dense feathering, which accounts for about eight percent of their body weight.
Despite the short northern breeding season, Golden-crowned Kinglets typically raise two large broods of 8-9 young.
The male Golden-crowned Kinglet often feeds the incubating female and later cares for the first brood alone while the female starts a second clutch.
05 / An eye for the difference
While sometimes found in mixed flocks, chickadees are larger with a prominent black cap and bib, lacking the kinglet's crown pattern.
Brown Creepers have a distinctive long, decurved bill, a streaked brown back, and creep up tree trunks, unlike the kinglet's foraging style.
