Skin Type Feathered body plumage; keratin bill; legs/feet with scaly skin typical of passerines (tarsi and toes).
Distinctive Features
  • Medium-sized North American tyrant flycatcher: total length 17-21 cm; wingspan 33-34 cm; mass 0.027-0.040 kg (commonly cited ranges in species accounts such as Cornell Lab of Ornithology 'All About Birds' and field guides).
  • Prominent but not oversized crest (often raised), helping separate it from similarly sized flycatchers without a noticeable crest.
  • Bold plumage contrast used for Myiarchus identification in eastern North America: gray throat/upper breast + bright yellow belly + rufous tail and wing tones.
  • Tail shows warm rufous/orange tones (especially inner webs) that can flash in flight or when the tail is fanned; a key field mark distinguishing it from many other flycatchers.
  • Two narrow pale wingbars often visible from light feather edging; overall wing looks dark with warm rufous highlights.
  • Typical Tyrannidae foraging behavior (often noted in identification): perch-and-sally insectivory-launches from exposed perches to seize flying insects, then returns to the same or nearby perch.
  • Cavity nester (natural holes or nest boxes); famously incorporates shed snakeskin (and sometimes other fibrous materials) into the nest lining-an iconic behavioral trait frequently cited in primary species accounts.
  • Longevity (banding record): reported maximum of 11 years 2 months in North American banding data (USGS Bird Banding Laboratory longevity records, as commonly summarized in ornithological references).
  • Breeds in eastern North America (southern Canada to the eastern U.S.) and winters in Mexico, Central America, and the Caribbean. Do not confuse with western/southwestern Myiarchus like Ash-throated or Brown-crested.

Did You Know?

Size: 17-21 cm long; wingspan 33-35 cm; mass ~0.027-0.040 kg (standard field measurements reported in major North American references such as Cornell Lab/Birds of the World).

Longevity record: 14 years 11 months (USGS Bird Banding Laboratory longevity data).

Breeding biology: typical clutch 4-8 eggs; incubation ~13-15 days; young fledge ~12-17 days after hatching (summarized in Birds of the World accounts).

A classic Tyrannidae hunter: launches from a perch, snaps insects in midair, and often returns to the same lookout ("perch-and-sally").

Nest trademark: frequently incorporates shed snakeskin (and sometimes onion skins/cellophane) into cavity nests-one of the most iconic Myiarchus behaviors.

Myiarchus ID tip: in the East, the combination of gray throat/chest, bright yellow belly, and extensive rufous in wings/tail strongly points to Great Crested Flycatcher; western Myiarchus are similar but differ subtly in voice and tone.

Diet isn't just insects: during migration and late summer it also takes fruit, helping it track seasonal food pulses in forest edges and openings.

Unique Adaptations

  • Wide, flat bill with rictal bristles: typical tyrant flycatcher "aerial net" design that helps funnel and sense insect prey during fast, open-mouthed strikes.
  • Rufous wings and tail: strong color contrast that flashes in flight-useful for field identification and potentially for intraspecific signaling during chases and courtship.
  • Cavity-nesting flexibility: ability to breed in natural cavities and nest boxes lets it exploit fragmented forests and suburban woodlots where large trees remain.
  • Snakeskin (and look-alike) nest additions: a specialized, repeatedly documented Myiarchus trait; proposed functions in the literature include predator deterrence and parasite reduction, and the species shows consistent selection for snake-skin-like materials.
  • Powerful sallying flight: short bursts from a fixed perch optimize energy use for catching aerial insects-an efficient Tyrannidae strategy across habitats.

Interesting Behaviors

  • Perch-and-sally foraging: chooses mid-level forest-edge perches, makes short aerial sallies for flying insects, then re-perches; also gleans prey from foliage and bark when swarms are scarce.
  • Cavity nesting (natural + human-made): uses tree cavities/woodpecker holes and readily accepts nest boxes; brings coarse material (twigs, leaves, hair, feathers) and often snakeskin into the cavity cup.
  • Distinct Myiarchus voice cues: gives sharp, rising "wheep!" and rolling calls that carry through summer woods-often detected by sound before seen (a key ID method for the genus).
  • Territorial defense: actively chases intruders near nest sites; pairs patrol edges and canopy openings where prey flights are predictable.
  • Opportunistic prey handling: beats larger insects (e.g., big beetles, cicadas) against perches to subdue them before swallowing.
  • Seasonal movements: migratory-breeds across eastern North America and winters primarily in the Caribbean, Central America, and northern South America; spring arrival is a reliable phenology marker in many regions.

Cultural Significance

Great Crested Flycatcher (Myiarchus crinitus) is a familiar "voice of summer" in eastern woodlands. It decorates nests with shed snakeskin, appears in nature writing and teaching about cavity nesting, predator-prey links, and the diversity of Myiarchus flycatchers, and uses nest boxes in parks and yards.

Myths & Legends

Rural North American local belief about the Great Crested Flycatcher (Myiarchus crinitus): its nest lined with snakeskin is thought to be a protective charm, scaring predators or keeping bad luck from the nest hole.

In some folk tales, finding snakeskin in a Great Crested Flycatcher (Myiarchus crinitus) nest meant snakes would come to the tree later, so people avoided the cavity—showing its odd nesting habit fueled warnings.

Ornithology tradition: "Great Crested" points to its slight peaked crown when alert, and the Latin name Myiarchus crinitus means "crested" or "hairy," showing early naturalists focused on its head shape.

Human Interaction

Domestication Status

Wild

The Great Crested Flycatcher (Myiarchus crinitus) is a wild, migratory songbird with no history of domestication. It has not been bred by people for tameness or use. It lives free and is usually handled only during permitted scientific banding, research, or wildlife rehabilitation, not as a pet.

Danger Level

Low
  • May aggressively defend the nest cavity (close fly-bys, snapping bill) if a person approaches or opens a nest box; risk is minor and typically limited to startling encounters.
  • As with most wild birds, nests can harbor ectoparasites (e.g., mites/flies); handling nest material without protection can pose a minor irritation risk.
  • No known special venom/toxin risk; does not pose a meaningful physical threat to humans under normal circumstances.

As a Pet

Not Suitable as Pet

Legality: Having a Great Crested Flycatcher (Myiarchus crinitus) as a pet is illegal in the United States without federal permits under the Migratory Bird Treaty Act (MBTA); Canada (Migratory Birds Convention Act) and most of its range have similar bans.

Animals that fill a similar ecological role in their ecosystem

Eastern Wood-Pewee Contopus virens Similar sit-and-wait aerial insectivore of forest openings; both species catch insects by sallying from open perches. The Great Crested Flycatcher is larger (16–21 cm body length, ~34 cm wingspan) and more likely to nest in cavities than pewees.
Eastern Phoebe
Eastern Phoebe Sayornis phoebe Both are perch-sallying insectivores found near edges and buildings; Eastern Phoebes build open cup nests on ledges or bridges, while Great Crested Flycatchers (Myiarchus crinitus) use cavities and often add snakeskin to their nests.
Western Kingbird
Western Kingbird Tyrannus verticalis Occurs in similar open-canopy edge, woodland, and agricultural settings and exhibits similar aerial hawking of large flying insects. Kingbirds are less cavity-dependent (typically open-cup nesters) but overlap strongly in foraging mode and prey types (large beetles, wasps, grasshoppers).
Red-eyed Vireo Vireo olivaceus Shares breeding habitat — deciduous/mixed forest canopy and edges — and heavily relies on arthropods during the breeding season; differs by foraging method (more foliage-gleaning than aerial sallying) and by nesting (builds open cup nests in shrubs/trees rather than nesting in cavities).

Quick Take

  • Reaching a 14-year lifespan is a rare achievement requiring specific mastery of the fly ruler hunting style.
  • The 7 or 8-inch height creates a specific vulnerability during the 15-day first flight developmental phase.
  • The inclusion of trash and fur in nests contradicts standard avian architecture.
  • The aerial ritualized behavior is a mandatory process for males attempting to enter a female’s nesting site.

The great crested flycatcher is a fascinating and elegant songbird with a big crest on its head and a luxurious mating call. Often obscured by foliage and trees, it’s usually heard more often than it’s seen. This species is considered to be a member of the tyrant flycatcher family, a diverse group of birds entirely native to the Americas.

3 Amazing Great Crested Flycatcher Facts

  • The great crested flycatcher is sometimes the victim of the brown-headed cowbird. “Brood parasitism” means that the interloper will lay its eggs in the flycatcher’s nest and hope the mother will raise the young as its own. Despite being raised by other birds, the cowbird still has its own species-specific calls.
  • The great crested flycatcher plays an important ecological role by controlling insect populations.
  • The flycatcher’s egg is colored creamy white to pink with brown, purple, or lavender spots.

Where to Find the Great Crested Flycatcher

The great crested flycatcher can be found in sparse woodlands and groves across the eastern United States and parts of Canada in the breeding season, then in Central and South America in the winter. They tend to live near the edge of forests, around open plains. Old woodpecker holes and tree cavities are chosen by the female as a nesting site.

Nests

The flycatcher’s nest is constructed high up in the canopy to avoid competition with other bird species. A large variety of nesting materials is used, including leaves, feathers, grass, string, fur, snakeskin, and trash.

Classification and Scientific Name

The scientific name of the great crested flycatcher is Myiarchus crinitus. The name Myiarchus, a large genus of 22 species, is derived from the combination of two Greek words, meaning roughly “fly ruler.” Crinitus means long-haired or especially hairy (even though the species obviously doesn’t have hair).

Size, Appearance, and Behavior

The great crested flycatcher is a medium-sized bird, measuring about 7 or 8 inches tall. It can be identified by the lemon-yellow stomach and the reddish-brown or blue-gray back, wings, and head. Other prominent features include the large crest and the long, narrow beak. Males and females are almost indistinguishable from each other, but juveniles are generally duller in color.

The great crested flycatcher is an agile flyer. It does the majority of its hunting in the air, usually around dawn or dusk, and does not come to the ground very often. This bird seems to be constantly on alert for intruders and threats, looking in all directions with its bobbing head.

Migration Pattern and Timing

Following the end of the breeding season, the great crested flycatcher migrates south for the winter. Most birds settle somewhere between Mexico and Colombia. They travel alone or in pairs.

Diet

The great crested flycatcher is an omnivore. They often sit on a high perch and wait for prey to pass by so they can swoop down and eat it. They will also sometimes hover near a plant and snatch the prey in their beaks. Almost none of their hunting and foraging is done on the ground.

What does the great crested flycatcher eat?

The flycatcher’s diet largely consists of insects. Some of its favorite foods include crickets, beetles, butterflies, moths, and, of course, flies. It will supplement this with spiders, small lizards, and fruits and berries (especially in its winter migration home). They will regurgitate the pits of the fruits after eating the soft flesh.

Predators, Threats, and Conservation Status

The great crested flycatcher is considered to be a species of least concern by the IUCN Red List, but some individual birds do fall victim to predators, pesticide poisoning, and habitat loss. Competition for scarce nesting sites is often fierce and difficult.

What eats the great crested flycatcher?

An adult bird doesn’t usually have much to fear from predators, but eggs and hatchlings are often vulnerable to snakes, squirrels, and other arboreal animals. It will make a fast, repeating call when a predator is spotted. If the predator doesn’t heed its warning, then it may dive down and attack.

Reproduction, Young, and Molting

The breeding season of the great crested flycatcher lasts every year between May and July. The male makes a three-part whistling song to attract a mate. The courtship is then sealed with a vaunted aerial ritualized behavior in which the male will swoop down at a potential mate and hope for a positive response. Sometimes, he will even pursue the female back to her nesting cavity. Once they’ve mated, the mother will lay four to six eggs and incubate them for about two weeks.

The young are later born helpless, naked, and without sight, entirely dependent on their parents. The female will provide much of the food for the hatchlings, while the male will defend the territory from intruders. The first flight begins around 13 to 15 days of age, but the juveniles remain with the parents for another three weeks. By the arrival of the next breeding season, the juveniles are ready to mate for the first time. The typical lifespan is thought to be around 10 years or more, but it’s difficult to estimate because few birds return to their original nesting location. The maximum recorded lifespan was 14 years.

Population

It’s estimated that some 8.8 million great crested flycatchers (mature individuals) are alive, according to Partners in Flight 2019. The population trend is currently considered stable.
