Ruby Crowned Kinglet Nesting and Habitat Facts Explained

The Ruby Crowned Kinglet is a tiny bird that calls North America home, and like many of its feathered friends, it's a skilled nest-builder.

These birds typically build their nests in coniferous trees, often using twigs, moss, and lichen to create a sturdy home.

In the Pacific Northwest, where the Ruby Crowned Kinglet is most commonly found, they tend to nest in Douglas Fir and Western Hemlock trees.

The Ruby-crowned Kinglet is one of America's smallest birds, recognized by its constant wing-flicking.

These tiny birds are found in spruce-fir forests in the northwestern United States and Canada, where they nest high in the trees.

The Ruby-crowned Kinglet lays a large clutch of eggs, each weighing only .02 of an ounce, but the entire clutch can weigh as much as the female herself.

Ruby-crowned Kinglets prey on spiders and many types of insects, including aphids, wasps, ants, and bark beetles.

They will also eat a small amount of seeds and fruit.

The Ruby-crowned Kinglet builds its nest by gathering grasses, feathers, mosses, spiderwebs, and cocoon silk for the outer structure and fine plant material and fur for the inner lining.

The nest is elastic enough that it can stretch as the brood grows.

Ruby-crowned Kinglets are quite the skilled nest builders. They typically construct their nests in conifers, usually 40 or more feet from the ground.

Females are the ones responsible for building the nests, which are deep and suspended from two hanging twigs. The nests are well hidden and protected from above by an overhanging branch.

The outer walls of the nest are made up of moss, grass, lichen, bark strips, twigs, rootlets, needles, and spider webs, while the soft lining is formed by feathers, plant down, and hair.

The females take the lead in building these nests, which are deep and suspended from two hanging twigs. They're well hidden and protected from above by an overhanging branch.

Moss, grass, lichen, bark strips, twigs, rootlets, needles, and spider webs make up the outer walls of the nest. The lining is a soft mix of feathers, plant down, and hair.

Ruby-crowned Kinglets have an impressive clutch size, with females laying up to 12 eggs in the Pacific Northwest. That's the largest clutch relative to size of any North American passerine.

Incubation lasts about two weeks, during which the male brings food to the female on the nest. After the eggs hatch, the female broods the young for a few days before joining the male in feeding them.

The young leave the nest about 16 days after hatching, and the male continues to feed them from the first brood for another 10 days.

Ruby-crowned Kinglets breed in dry, open, coniferous and mixed forests at high elevations, typically in small forest openings or wetlands within these forest zones.

They prefer higher, drier habitats than Golden-crowned Kinglets.

In these habitats, they nest in areas with open spaces and access to water, which is crucial for their survival.

During migration and in winter, Ruby-crowned Kinglets come down into the lowlands and can be found in a wide variety of forest and shrub habitats.

This flexibility in habitat allows them to adapt to changing environments and find food and shelter when needed.
