What’s happening with the chickadee?

Chickadees are active, acrobatic, curious, social birds that live in flocks, often associating with woodpeckers, nuthatches, warblers, vireos, and other small woodland species. They feed on insects and seeds, but seldom perch within several feet of one another while taking food or eating. Flocks have many calls with specific meanings, and they may contain some of the characteristics of human language.Back to top


Black-capped Chickadee Life History

Habitat Forests

Chickadees are found in deciduous and mixed forests, open woods, parks, willow thickets, cottonwood groves, and disturbed areas.Back to top

Food Insects

In winter Black-capped Chickadees eat about half seeds, berries, and other plant matter, and half animal food (insects, spiders, suet, and sometimes fat and bits of meat from frozen carcasses). In spring, summer, and fall, insects, spiders, and other animal food make up 80-90 percent of their diet. At feeders they take mostly sunflower seeds, peanuts, suet, peanut butter, and mealworms. They peck a hole in the shell, and then chip out and eat tiny bits of seed while expanding the hole.Back to top

Nesting

Nest Placement

Nest Cavity

Nest boxes, small natural cavities, or abandoned Downy Woodpecker cavities; often excavate their own cavities. In the case of next boxes, seem to prefer to excavate wood shavings or sawdust rather than to take an empty box. Nests can be at ground level to more than 20 m high, but are usually between 1.5 and 7 m high. They tend to excavate in dead snags or rotten branches, and often select alder or birch.

Nest Description

Both male and female chickadees excavate a cavity in a site usually selected by the female. Once the nest chamber is hollowed out (it averages 21 cm deep) the female builds the cup-shaped nest hidden within, using moss and other coarse material for the foundation and lining it with softer material such as rabbit fur.

Conservation Low Concern

Black-capped Chickadees are common and overall populations increased slightly between 1966 and 2019, according to the North American Breeding Bird Survey. Their western populations slightly declined during this time, but the loss was made up by an increase in eastern populations. Partners in Flight estimates the global breeding population at 43 million. The species rates a 7 out of 20 on the Continental Concern Score, indicating a species of low conservation concern. Forest clearing for agriculture or development can increase the amount of forest edge, which can improve habitat for chickadees, and this species also benefits from people who keep bird feeders. As with many birds that nest in tree cavities, chickadees can suffer if land managers cut too many dead trees out of forests.


Black-Capped Chickadee

Black-capped chickadees are named for the “cap” of black feathers that covers the top of the bird’s head and extends just below the eyes. Their cheeks and chest are white, their wings are gray with white edges, and their sides are beige. Adult black-capped chickadees are just four to six inches (10 to 15 centimeters) long with a wingspan of six to eight inches (15 to 20 centimeters).

Black-capped chickadees are non-migratory. They are found year-round from New England to the West Coast. In the West, their range extends as far south as New Mexico. In the east, they follow the Appalachian Mountains south to Georgia. Canadian residents and Alaskans can observe black-capped chickadees near their homes as well.

Black-capped chickadees are found in deciduous and mixed deciduous-evergreen forests, especially near forest edges. They are commonly found near willows and cottonwoods, and like to make their nests in the snags of alder and birch trees. Feeders and nest boxes can be used to attract chickadees to suburban backyards.

Hawks, owls, and shrikes capture adult chickadees, but nestlings and eggs are in more danger of being consumed by tree-climbing mammals. A chickadee’s alarm call sounds just like its name. Chickadees warn their flocks of nearby predators by sounding out “chickadee-dee-dee!”

Like many birds, black-capped chickadees are omnivorous. They eat a diet of seeds, berries, insects, invertebrates, and occasionally small portions of carrion. Chickadees also love to eat suet and peanut butter offered at bird feeders. However, chickadees have a penchant for storing food and eating it later, so they usually won’t stick around at a feeder for very long. They place food items in a number of different hidden locations, so chickadees must have excellent memories to keep track of their food.

Male and female chickadees excavate nest cavities in the soft, rotting wood of snags or build nests in abandoned woodpecker cavities. They also take readily to nest boxes filled with wood shavings. Females build the nest and fill it with up to 13 eggs. The male brings her food while she warms the eggs, and both parents take part in raising the young.

The average lifespan for black-capped chickadees is less than two to three years. The oldest chickadee on record was a male that lived for over 11.5 years.

Black-capped chickadee numbers are increasing due to large amounts of forest edge habitat, as well as nesting and feeding opportunities in backyards.

Chickadees are social birds that live in flocks. To keep up with changes within the flock—and to remember food cache locations—chickadees are able to replace old neurons with new ones. This essentially wipes out old memories and gives the birds more space to store new information.
