Birds With Friends: The Golden-Crowned Kinglet


The golden crowned kinglet (Regulus satrapa) is slightly bigger than a hummingbird, with rounded body and short wings. Its head is relatively large, with a thin tail and a short and thin beak. It has a distinctive black eyebrow stripe with a bright yellow crest. Its wings and back are olive with white wingbars and its underbelly is gray. The golden crowned kinglet is notoriously difficult to sight and study because it nests and forages high up in dense conifer forests.

Golden crowned kinglets prefer a woodland habitat, specifically old growth forests near water where, in boreal regions, they nest in spruce or fir trees. In the Americas, their wide breeding range reaches from the northern Appalachian region west to southern Alaska. Areas where they are present but do not breed span across the U.S. In New York state, the golden-crowned kinglet lives year round, breeding in pine, mixed pine, spruce, balsam fir, and hemlock trees found in bogs, parks, or cemeteries. Golden-crowned kinglets live year round in a few other regions, such as North America’s west coast from southern Alaska to San Francisco, eastern California, the Southwest, and the Northeast. Other than a year-round population in the Central American volcanic belt, they have not been recorded living outside the Americas.

There is limited information about the breeding patterns of golden-crowned kinglets. It seems likely that they are serially monogamous because both males and females are heavily involved in feeding nestlings. During the nest-building and egg-laying period, the male follows the female around. She initiates copulation by calling to him, flattening herself out on a twig, and fluttering her wings; copulation can last up to 7 seconds.

Golden-crowned kinglets lay two clutches of eggs each season. Most observations of nesting are of a population of birds in Northern Minnesota, and there the first clutch usually appears in mid- to late May and the second in late June. The deep, cup-shaped nests are usually located high up in dense conifer stands. They hang from twigs below a branch and are built of a wide range of materials including moss, lichen, bark, spiderwebs, twigs and leaves, and lined with softer materials like feathers or plant down (Kaufman).

Just after hatching, kinglets are very “altricial,” i.e. they are highly dependent and weak, naked and about the size of bumblebees. Females brood the young for the first 3-5 days after the eggs hatch. During that initial period the parents eat the nestlings’ fecal sacs; later on, they carry the sacs away and deposit them away from the nest. Both females and males go on feeding trips, but the male brings more food during the brooding period and also much later on, when the female begins to brood her new clutch of eggs. Young leave the nest about 16-19 days after hatching, but continue to be dependent on parents for food for some time after. By 12-16 days after fledging, young are catching mostly their own food, and are totally independent by 17 days later.

The diet of golden-crowned kinglets varies with the seasons. In winter, these birds eat soft bodied arthropods like spiders, bark lice, grasshoppers, caterpillars, small beetles, gnats, and crickets as well as their eggs. During the breeding season, golden-crowned kinglets still eat arthropods but not their eggs. During this period, fruit is added to their diet, but in small amounts (Kaufman 1996). Mostly foraging high on conifers, the golden-crowned kinglet gleans insects from pine needles, hovers to pick insects from bark, and hawks for aerial insects. In the presence of certain species like the Carolina Chickadee or the Tufted Titmouse, the golden-crowned kinglet shifts its foraging area in hopes of avoiding them (All About Birds).

Social Life

Not much of their migratory and social patterns is known. Most of the golden-crowned kinglet’s chosen habitats are home to cold winters. During these winters, kinglets will sometimes migrate to lower altitudes and other times stay behind. When they do not migrate, golden-crowned kinglets endure the cold winters in a few ways. For one, eight percent of their body weight (only six grams, the equivalent of two pennies) is attributed to their feathers, insulating them from the cold and keeping their internal body temperature at 110°F. Moving through the forest in flocks, golden-crowned kinglets feed constantly during the winter, foraging at a rate of almost one peck per second for small caterpillars. At night, two to four individuals huddle together in dense conifer foliage to conserve heat (Heinrich 2003). During the fall and winter, golden-crowned kinglets often join large flocks, both intra- and interspecific flocks. Varying with location, they have been known to flock with ruby-crowned kinglets, pine warblers, mountain chickadees, yellow-rumped warblers, and downy woodpeckers. In the interspecific flocks, the golden-crowned kinglets are more often followers than leaders. Apart from flocking, the golden-crowned kinglet’s intraspecific interactions also include territorial aggression; in territorial intrusions during the breeding season, males confront the intruder and, if needed, fight them off.

    Do you think you could give me some info on the life cycle of the Golden-crowned Kinglet? It would be very nice of you!

    I have two kinglets frequenting my cedar tree: a ruby-crowned and a golden-crowned. I was surprised to see them together. Are they definitely different species? Is it possible that they’re two varieties of the same species? I’m 100% certain that both frequent the same tree since my study window is just a few feet from them. Is it common for two similar species to be found together?
