Missouri State Bird – Eastern Bluebird

Missouri selected the Eastern Bluebird in 1927. Schoolchildren backed the choice in a statewide vote. Birds perch on fence posts across rolling countryside. Blue plumage shows clearly in sunlight. Chest feathers appear rusty above a pale belly. Residents knew the species well before lawmakers acted.

Why Missouri Chose This Bird

Missouri picked the bluebird for its statewide presence. The species appeared common to lawmakers. You heard males singing from fence posts each spring. Farmers watched them hunt insects across fields.

Henry David Thoreau wrote the bird 'carries the sky on its back'. This description appealed to Missouri officials. Blue, white, and red plumage created visual contrast. Bluebirds avoid conflicts with other species. Pleasant songs attracted attention. Insect control benefited farmers and gardeners.

Rolling countryside provides ideal bluebird habitat. Open grasslands support insect hunting. Scattered trees offer perching and nesting sites. Fence posts appear every hundred yards across farmland. This landscape suits bluebird needs.

Legislative History

  1. 1927 Designation

    Missouri’s legislature designated the native bluebird as the state bird in 1927. Lawmakers later updated the wording in the mid-20th century to reference the species by its scientific name. The designation has remained consistent ever since.

  2. Shared Symbol

    Only one other state shares this bird. New York adopted the Eastern Bluebird decades after Missouri, following a long public campaign that began with schoolchildren. Missouri was the first state to recognize the species officially.

What This Bird Represents

Happiness Symbol

People connected bluebirds with joy decades before 1927. Bright colors suggested cheerfulness. Pleasant song reinforced the idea. Seeing a bluebird improved your morning. Missouri made official what farmers understood.

Rolling Countryside Connection

These birds favor Missouri's terrain. Not deep forest. Not wide-open prairie. The in-between zones. Pastures with fence lines. Orchards with grass underneath. Cemeteries with scattered oaks. Watch bluebirds work those spaces. Perch high. Scan low. Drop fast when they spot movement.

Pest Control Value

Farmers appreciated bluebird diets. Grasshoppers, crickets, beetles—all crop pests. Getting free pest control beat buying chemicals. Gardens benefited too. Yard insects disappeared when bluebirds nested nearby. Natural solution.

Physical Characteristics

Male Appearance

Males show cobalt blue across back, wings, tail, head, chin, and throat. Bright enough to spot from far off. Chestnut coloring covers the upper breast. Sometimes extends onto the back. White belly contrasts with everything above. Look for the pattern: blue-rust-white, top to bottom.

Female Coloring

Females wear paler versions of male patterns. Gray-blue replaces cobalt. Rusty tones fade to buff. Still pretty. Just subtler. Smart design—females need camouflage while sitting on eggs. Hidden birds survive better.

Size and Build

Length runs 6-7 inches nose to tail. Wingspan stretches 10-13 inches. Weight? Around an ounce. Small thrush build. Plump body, short straight bill. Legs stay short. Tail too. Wings run long compared to body size.

Juvenile Features

Young birds puzzle people. Brown and speckled underneath. Blue traces show on wings and back. Spots work like camouflage. Predators overlook speckled birds easier than bright ones. Feathers molt by fall. Juveniles gain adult colors after breeding season ends.

Behavior and Song

Vocal Patterns

Song translates as "cheer cheerful charmer" or "chur-a-lee." Blurry whistled series. Some people hear "turee" or "queedle." Calls include soft "chuiree" with descent then rise at the end. Males sing most. Spring brings territory claims through constant warbling. Mate attraction. General cheerfulness.

Hunting Strategy

Watch bluebirds work. They perch low—fence wire, branch, post. Scan the ground. Spot movement. Drop fast. Grab the bug. Fly back up. Repeat fifty times a day. Sometimes they hover rather than landing. Catch flying insects mid-air too. Excellent eyesight spots tiny prey from 60 feet away.

Territorial Defense

Males guard nesting areas hard. Chase off other bluebirds. Attack tree swallows, chickadees, anyone who wants the cavity. Spring brings fights. Even attack their reflections in windows. Mistake glass images for intruders. Keep fighting until breeding ends.

Family Dynamics

Both parents feed nestlings. Male brings food. Female broods and feeds. Sometimes older offspring from first brood help with second brood. Teamwork raises more babies. Young birds leave nest around 18 days old. Parents keep feeding them though. Teaching hunting skills takes time.

Habitat and Range

Missouri Distribution

Found statewide. Year-round residents in southern Missouri. Northern birds migrate south for winter. You spot them in grasslands with scattered trees. Farmland works. Backyards in rural areas. Parks and cemeteries too—anywhere with short grass and perching spots.

Seasonal Patterns

Spring brings territory claiming. March starts the action. Breeding runs through summer. Two broods common. Sometimes three in warm years. September changes things. Northern flocks drift south. Family groups join larger wandering flocks from mid-September through December. Some Missourians see bluebirds all winter. Southern counties especially.

Winter Survival

Cold weather tests bluebirds. They crowd into cavities together for warmth. Switch diets from insects to berries. Dogwood, sumac, cedar, hawthorn fruits keep them alive. Fresh water becomes critical. Several days of sub-freezing temperatures with snow or ice cover can cause mass mortality. Late 1970s winters killed so many birds Missouri's population took nearly a decade recovering.

Conservation Success

Populations declined last century. Habitat loss hurt. Pesticides killed insects they needed. Competition from house sparrows and European starlings created problems. Aggressive non-native species forced bluebirds out of natural cavities. Conservation groups responded with nest box programs. Thousands installed statewide. Bluebirds accepted artificial homes. Numbers rebounded. Now you see them along Missouri roadsides. Perched on utility wires and fence posts.

Interesting Facts

Fact 1 of 10

Bluebirds don't eat seeds. Never visit regular bird feeders. Attract them with mealworms instead. Cornmeal cakes mixed with bacon drippings work. Dried berries too.

People Also Ask

When did Missouri adopt the Eastern Bluebird as state bird?
Missouri designated the Eastern Bluebird as official state bird in 1927 through Senate Bill 321. Legislature chose it because bluebirds were common across Missouri. Represented happiness too. The law was later revised and recodified in 1957. Updated statute approved on June 13. Took effect August 28 that year.
Why did Missouri choose the bluebird over other species?
Schoolchildren and legislators picked the bluebird for practical reasons. It was common statewide. People saw them regularly. The bird's pleasant song appealed to voters. Non-aggressive behavior helped. Beneficial insect-eating habits mattered. The red, white, and blue coloring suggested patriotic symbolism. Henry David Thoreau's description of the bird 'carrying the sky on its back' captured how people felt about seeing these birds in Missouri's rolling countryside.
How many U.S. states share the Eastern Bluebird as their official bird?
Seven U.S. states claim the Eastern Bluebird as their official bird: Missouri (1927), New York (1970), Illinois, Indiana, Kentucky, North Carolina, Ohio, Virginia, and West Virginia. Missouri was among the first states to designate this species. Started a trend. Other legislatures followed over subsequent decades.
What does the Eastern Bluebird eat in Missouri?
Spring and summer diet consists of insects. Grasshoppers, crickets, beetles, caterpillars, spiders, earthworms. They hunt by perching on fence posts or low branches. Scan the ground. Swoop down to catch prey. Winter diet shifts to berries. Dogwood, sumac, cedar, hawthorn, similar plants. Bluebirds never eat seeds. Won't visit regular bird feeders.
Where can I see Eastern Bluebirds in Missouri?
Eastern Bluebirds live statewide in Missouri. Southern counties have year-round residents. Northern populations migrate south in winter. Look for them in open grasslands with scattered trees. Farmland with fence lines works. Rural backyards, parks, cemeteries, orchards. Along roadsides too. You'll often spot them perched on utility wires, fence posts, or low branches. Scanning the ground for insects.
How can I attract bluebirds to my Missouri property?
Install nest boxes with 1.5-inch entrance holes. Mount them 4-6 feet high on posts. Pick open areas with short grass and scattered trees. Space boxes at least 100-125 yards apart. Clean boxes before breeding season (March). Between broods too. Provide mealworms since bluebirds don't eat seeds. Cornmeal cakes with bacon drippings work. Dried berries help. Plant native berry producers like dogwood, sumac, and cedar. Supply fresh water year-round. Especially in winter.
Why did Eastern Bluebird populations decline in Missouri?
Multiple factors caused declines through the mid-1900s. Habitat loss from development reduced available nesting sites. Pesticide use killed insects bluebirds needed for food. Competition from invasive European species created problems. House sparrows and starlings forced bluebirds out of natural tree cavities. Wooden fence posts that provided nesting spots got replaced. Metal and treated wood took their place. Hard winters in the late 1970s caused mass mortality. Took nearly a decade for populations to recover.
Are Missouri's bluebird populations stable now?
Yes. Conservation efforts successfully revived Eastern Bluebird populations across Missouri. Thousands of nest boxes installed statewide provided artificial nesting sites. Bluebirds accepted them readily. The Missouri Department of Conservation monitors populations. Citizen groups help. Current populations appear healthy. Bluebirds are commonly seen along roadsides now. In parks too. Across farmland throughout the state. Continued monitoring and nest box maintenance helps sustain recovery.
