Size

4.3 - 5.5 in/0.2 oz

Habitat

Primary habitat

The bushtit primarily inhabits a variety of wooded or brushy habitats such as oak scrubs, chaparral, mixed woods, pinyons, and junipers. This includes oak forests and pinyon-juniper and pine-oak woods.

Additional range

In addition to its primary habitats, the bushtit can be found in streamside groves and well-wooded suburbs and city parks. The bird avoids high mountain and desert regions, but may occupy cottonwood-willow groves along desert streams in winter.

What do bushtits like to eat?

Natural diet

The bushtit's natural diet consists mostly of insects. It feeds on a diverse array of tiny insects, including leafhoppers, treehoppers, aphids, scale insects, caterpillars, and beetles. It also consumes wasps, ants, and many other insects, as well as the eggs and pupae of various insects. Occasionally, the bushtit eats spiders, berries, and sometimes seeds.

Bird feeders

Bushtits may not frequent bird feeders as much as other birds but they can occasionally be drawn to feeders offering suet or mealworms, which mimic their natural insect diet. While not a primary source of food, these offerings can supplement their diet especially in less abundant seasons.

What does a bushtit sound like?

Bushtits have a variety of vocalizations. Their typical contact calls, which they perform consistently, consist of soft tsip and pit notes that are light in tone. When threatened, they emit a distinctive high, trilling alarm call. In terms of call patterns, it is noted to be flat and the type of call can be categorized as chatter or chirp/chip. Overall, the bushtit's vocal expressions are diverse, comprising both rhythmic and sharp notes.

Mountain Chickadee

Poecile gambeli

How to recognise a mountain chickadee?

General appearance

The mountain chickadee is approximately 5-5 3/4 inches (13-15 cm) long, roughly the size of a sparrow. Its characteristic features include a black cap and bib. A distinctive white eyebrow, which may be broad or narrow, breaks the black cap. Their wings are rounded while the tail shape varies from notched to rounded or square-tipped. They sport the colors of nature: black, gray, and white.

Male vs female

Males and females of the mountain chickadee species are identical in their physical appearance and there are no significant size or color variations between the two. They both sport the same black cap, whites eyebrow, and gray body coloration.

Juvenile

Young mountain chickadees resemble adults, but their plumages may be less vibrant and the distinct white eyebrow may be difficult to make out. Depending on the season, the plumage of all mountain chickadees, including juveniles, may be in worn condition, making the white eyebrow particularly difficult to see.

Size

4.7 - 5.9 in/0.3 - 0.5 oz

Habitat

Primary habitat

Mountain chickadees prefer high-altitude coniferous forests, especially of pine, spruce, fir, or Douglas-fir. They are also found in aspen groves within these zones, and lower habitats such as pine-oak and pinyon-juniper.

Additional range

While their primary range is in mountain forests, they may wander to lowlands in winter. Here they inhabit planted conifers if available, and occasionally breed in cottonwood groves.

What do mountain chickadees like to eat?

Natural diet

The mountain chickadee primarily consumes a variety of insects, seeds, and berries. It feeds on many types of insects, including caterpillars, beetles, and other varieties. The bird also targets insect eggs and pupae, along with spiders and their eggs. In addition to these protein sources, the mountain chickadee enjoys seeds, berries, and small fruits as part of its diet.

Bird feeders

At bird feeders, mountain chickadees are known to consume sunflower seeds and suet. They may also eat nuts and peanuts, along with any other small seeds provided. These birds are frequent and adaptable visitors to backyard feeders, enjoying a wide variety of offerings that mimic parts of their natural diet.

What does a mountain chickadee sound like?

The mountain chickadee communicates through various vocalizations including a hoarse chick-a-zee-zee, zee that exudes a spring-time feel similar to the Black-capped Chickadee's melody. It also produces a distinctive 3-noted call pattern: fee-bee-bee, with the bevocalizations sounding at a lower pitch. Its calls encompass a unique blend of falling, flat sounds that can be categorized into buzzes, chirps or chips, trills, and whistles.

How to tell the Bushtit from the Mountain Chickadee

Visual differences

The Bushtit is smaller, measuring about 3 3/4 - 4 inches long, compared to the Mountain Chickadee's 5-5 3/4 inches. The Bushtit has a small bill, a long, wedge-shaped tail, and features colors ranging from black, brown, gray, to tan and white. In contrast, the Mountain Chickadee is notable for its black cap and bib, a distinctive white eyebrow, and a gray body. Additionally, Bushtits have a distinct male/female eye color difference, while Mountain Chickadees exhibit no sexual dimorphism.

Key differences and behavior

Bushtits and Mountain Chickadees, though similar in size, exhibit distinct behavioral and ecological differences. Bushtits are social, often seen in large, vocal flocks in wooded suburbs and open woods, focusing on an insect-based diet. They use spiderwebs and plant materials to build hanging nests, and they adapt to varied environments except deserts and high mountains. In contrast, Mountain Chickadees thrive in high-altitude coniferous forests, often moving to lower elevations in winter. They exhibit acrobatics, such as hanging upside-down to eat a diverse diet of insects and seeds and are frequent feeder visitors. Chickadees nest in cavities using prepared materials, sometimes returning to the same site, and exhibit pair bonding behaviors like mutual preening, differing from the less territorial Bushtit nesting habits.
