Massachusetts State Bird: Black-capped Chickadee
Fact-checked • Updated November 25, 2025
Massachusetts State Bird – Black-capped Chickadee
The Black-capped Chickadee became Massachusetts’s official state bird on March 21, 1941. Maine selected the same species in 1927. Adults show a black cap, pale belly, and short bill. Populations remain through winter. Birds stay active in forests and neighborhoods when many other species migrate.
Why Was the Black-capped Chickadee Chosen?
Massachusetts picked the Black-capped Chickadee in 1941 after watching these birds thrive in every corner of the Commonwealth. Walk through Boston Common or hike the Berkshires, you'll spot them. They nest in suburbs, forage in city parks, explore deep woods. The legislature wanted a bird people knew from their own backyards, not some rare species hiding in remote forests.
Chickadees act friendly around people in ways most wild birds don't. Hold out seeds on your palm and stay still. They land right on your hand. Kids love this. Adults remember feeding chickadees as one of their first wildlife encounters. The bird's acrobatic moves while eating, hanging upside down from branches, spinning around twigs to grab insects, all of this makes chickadees entertaining to watch.
The State Federation of Women's Clubs pushed for the veery as state bird back in 1931. Lawmakers rejected the robin. A decade later, they revisited the question and selected the chickadee. Chickadees adapt to diverse habitats across Massachusetts, from coastal areas to river valleys to interior forests.
History and Legislation
-
The 1941 Designation
Massachusetts formally adopted the Black-capped Chickadee as state bird on March 21, 1941. The law sits in Chapter 2, Section 9 of the General Laws. Maine had already claimed this species 14 years earlier, so Massachusetts became the second state to honor the chickadee.

Shared State Bird
Two New England states celebrate the Black-capped Chickadee. Maine went first in 1927. Massachusetts followed in 1941. Both states appreciate how these small birds handle brutal winters without leaving. You find chickadees across New England forests every month of the year, even during January blizzards.
Symbolism and Cultural Significance
Symbol of Resilience
The Black-capped Chickadee represents how Massachusetts residents push through harsh conditions. These tiny birds weigh half an ounce but survive winters that kill larger species. Cold nights force chickadees to drop their body temperature by 12 degrees Celsius, entering a torpor-like state to save energy. This survival strategy mirrors the toughness Bay State communities showed during colonial winters and industrial challenges.
Year-Round Neighbor
Most songbirds abandon Massachusetts when leaves fall. Chickadees stay put. You spot them pulling seeds from feeders in July heat and January ice storms. Their refusal to migrate makes them constant companions for residents who watch birds from kitchen windows. Mass Audubon tracks chickadee populations in all 351 cities and towns across the state.
Physical Characteristics
Size and Build
Black-capped Chickadees stretch 4.7 to 5.9 inches from beak to tail. Wings span 6.3 to 8.3 inches when spread. Weight tops out at half an ounce, about the same as five pennies. Their round, plump body gives them a ball-like shape. The head looks oversized compared to the short neck and compact frame.
Distinctive Markings
A black cap covers the top of the head. Black feathers form a bib under the chin. Bright white cheeks sit between these dark patches, creating sharp contrast. The back shows gray-green tones. Wings appear darker gray with white edges along the feathers. White belly feathers transition to buff-colored sides near the wings. Males and females wear identical plumage, making them impossible to tell apart by sight alone.
Similar Species
Carolina Chickadees look nearly identical to Black-capped Chickadees. Their ranges meet in a narrow zone where the two species sometimes interbreed. Black-capped Chickadees show a cleaner bib edge and different wing patterns up close. Calls differ more reliably than appearance, with Black-capped Chickadees producing a slower, lower-pitched fee-bee song.
Behavior and Habits
Complex Vocalizations
Chickadees produce at least 16 distinct calls for different situations. The famous chick-a-dee-dee-dee call warns flock members about threats. Scientists discovered that more dee notes mean bigger danger, so a cat gets more dees than a pigeon. Males whistle a clear fee-bee song during spring to claim territory and attract mates. The first note drops in pitch compared to the second.
Food Caching Behavior
Every fall, Black-capped Chickadees hide thousands of seeds and insects in tree bark cracks and under leaves. They scatter these caches across their territory instead of storing food in one spot. Individual birds remember where they hid each item for up to 30 days. The hippocampus section of their brain grows 30 percent larger during caching season to handle all this spatial memory. A single chickadee stores up to 80,000 food items each year.
Social Flocks
Winter brings chickadees together into flocks with strict pecking orders. Males dominate females. Older birds push around younger ones. Each bird knows its rank and defers to higher-ranking flock members at feeders. Other species tag along with chickadee flocks, nuthatches and titmice and small woodpeckers, all benefiting when chickadees spot predators or find good feeding areas.
Acrobatic Foraging
Chickadees bounce along branches picking insects off bark surfaces. They flip upside down to check the underside of twigs where other birds miss hidden bugs. Strong feet grip bark while they lean out at odd angles. Sometimes they hover for a second to snatch flying insects mid-air. At backyard feeders, they grab one sunflower seed, fly to a nearby branch, hold the seed with their feet, and hammer it open with their beak.
Habitat and Conservation
Preferred Habitats
Black-capped Chickadees thrive where deciduous trees mix with conifers. Forest edges between woods and open areas give them ideal hunting grounds. Birch and alder trees attract them because these species host lots of insects. City parks work fine if mature trees grow there. Suburban neighborhoods with oak, maple, and pine trees support stable chickadee populations year-round.
Nesting Sites
Chickadees excavate their own nest holes in dead wood or soft tree sections. Both male and female chip away at several potential sites before the female picks one. She lines the chosen cavity with moss, animal fur, and feathers to create a soft cup. They also move into abandoned woodpecker holes or nest boxes people install. The entrance hole needs to measure 1.25 inches across, small enough to keep out starlings and house sparrows.
Conservation Status
The International Union for Conservation of Nature rates the Black-capped Chickadee as Least Concern. Populations hold steady or increase across Massachusetts. Suburban development creates more forest edge habitat, which chickadees prefer over dense woods. Backyard feeders help birds survive hard winters when natural food runs scarce. The species faces no major threats right now.
Helping Chickadees
Fill feeders with black oil sunflower seeds and suet blocks. Plant native trees and shrubs that produce berries and attract insects. Put up nest boxes with 1.25-inch entrance holes facing away from prevailing winds. Keep pet cats inside during nesting season from April through July. Skip pesticides that kill caterpillars and other insects chickadees need to feed their young.
Diet and Feeding
Seasonal Diet Changes
Spring and summer diets run 80 to 90 percent insects. Caterpillars pack the protein baby chickadees need to grow. Parents stuff dozens of caterpillars down chick throats each day. Fall arrival shifts the menu to half insects and half plant material. Winter forces chickadees to rely on cached seeds, frozen insect eggs, and whatever they find at feeders.
Preferred Foods
Chickadees hunt caterpillars, spiders, beetles, aphids, and insect eggs all year. They eat seeds from dozens of plant species, including poison ivy berries that would sicken people. Backyard feeders draw them in with sunflower seeds, shelled peanuts, and beef suet. Wild berries from bayberry, blackberry, and blueberry bushes supplement their diet when available.
Reproduction and Life Cycle
Pair Formation
Chickadees start pairing up in fall, months before breeding season. Males chase females through branches in courtship flights. Some pairs stick together for multiple breeding seasons or even life. The male feeds his mate while she builds the nest and incubates eggs, showing his ability to provide for a family.
Nesting and Eggs
Females lay clutches of 6 to 8 white eggs covered with small reddish-brown spots. She sits on the eggs alone for 12 to 13 days, leaving only for quick feeding breaks. When she exits the nest, she covers the eggs with nest material to hide them from predators and keep them warm. The male brings food to her throughout incubation.
Raising Young
Chicks break out of their eggs blind and naked. The female broods them constantly for the first few days while the male hunts for food. After about five days, both parents start bringing meals to the nestlings. Chicks grow fast on a diet of caterpillars and other soft insects. They leave the nest around 16 days after hatching but follow parents for another few weeks while learning to find food. Chickadees raise one brood per season.
Interesting Facts
Fact 1 of 8
Chickadees drop their body temperature by 12 degrees Celsius on freezing nights, entering a controlled hypothermia similar to torpor. This adaptation saves enough energy to survive until morning.
