American Bushtit
Psaltriparus minimus
The American Bushtit is a remarkably small and social songbird, often seen in active flocks moving through western North America. These plump, long-tailed birds are the only species of their family (Aegithalidae) found in the Americas. They are known for their constant movement and soft vocalizations as they forage.

01 / The telltale details
You’ll know it
when you see it.
Start with shape and behavior. Then look for the smaller details.
- 01
Overall Appearance
Tiny, plain gray-brown bird with a plump body, large head, short bill, and a relatively long tail.
- 02
Eye Color
Adult males typically have dark eyes, while adult females have pale yellow or white eyes.
- 03
Head Markings
Plumage varies regionally; coastal birds often have a brown crown, while inland birds may have tan cheeks or a brownish mask. Some in Mexico and Central America have black cheeks.
- 04
Flight
Flies weakly, often in a straggling single file when moving between trees.
02 / A place in the world
Where life
takes it.
American Bushtits inhabit a variety of wooded and brushy areas, including open woodlands, mixed pine-oak forests, chaparral, and streamside thickets. They also adapt well to suburban parks and gardens. They generally avoid high mountains and hot desert regions.
Stay a while. Or follow the season.
Bushtits are primarily year-round residents throughout their range. While generally non-migratory, they may undertake short-distance movements outside of the breeding season, especially in winter, and range widely in search of food.
03 / Listen a little closer
A voice
of its own.
They are quite vocal, communicating with continuous, high-pitched, wispy or lisping chips and twitters. These contact calls help keep the flock together.
04 / The life behind the feathers
A day in its world.
On the menu.
Their diet consists mainly of small insects and spiders, including aphids, scale insects, leafhoppers, caterpillars, beetles, wasps, and ants. During colder weather, they may also consume berries, fruits, and small seeds.
Bushtits are active, acrobatic foragers, often moving quickly through vegetation in flocks. They frequently hang upside down to glean insects and spiders from the undersides of leaves and pine needles.
A place to begin.
Both sexes construct a remarkable, pendulous, sock-shaped nest, often up to a foot long, woven from spider webs, plant material, lichen, feathers, and fur. The nest has a side entrance near the top.
The little routines.
Highly social birds, Bushtits typically travel in lively flocks of 10 to 40 or more individuals, especially outside the breeding season. They communicate constantly with soft calls and may huddle together for warmth on cold nights.
One more reason to pay attention
A familiar face.
A few surprises.
The American Bushtit is the only member of its family (Aegithalidae) found in the Americas; other species are in Eurasia.
Adult males often act as helpers at the nest, assisting the breeding pair in raising young, a rare behavior among cooperatively nesting birds.
All family members, including helpers, may sleep together in their large, hanging nest during the breeding season.
05 / An eye for the difference
Could it be
someone else?
Juniper Titmouse
Baeolophus ridgwayiJuniper Titmice are substantially larger and possess a short crest, unlike the crestless Bushtit.
Mountain Chickadee
Poecile gambeliMountain Chickadees are larger with a distinctive black cap and bib, and white eyebrow stripe.
