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.

Chestnut-Backed Chickadee

Poecile rufescens

How to recognise a chestnut-backed chickadee?

General appearance

The chestnut-backed chickadee is a small bird, roughly the size of a sparrow. Measuring about 4 1/2 -5 inches from beak to tail, this variety stands out due to its distinctive color scheme. It flaunts a rich chestnut back and sides, contrasting with its sooty brown cap and gray wings. Some variations found on the central California coast have gray sides instead of chestnut but are always more deeply colored in areas overlapping with the Boreal Chickadee.

Male vs female

The chestnut-backed chickadee exhibits little to no sexual dimorphism. This means that males and females of the species are very similar in appearance, making them difficult to distinguish based on physical characteristics alone.

Juvenile

Juvenile chestnut-backed chickadees closely resemble adults, but they may be slightly duller in color. As they mature, the rich chestnut and contrasting gray of their plumage become more pronounced. Notably, they do not undergo any significant seasonal variations in their appearance. Therefore, identification throughout the year remains consistent.

Size

3.9 - 4.9 in/0.3 - 0.4 oz

Habitat

Primary habitat

The chestnut-backed chickadee primarily favors dense, moist coniferous forests populated with spruce, fir, tamarack, hemlock, and other conifer species.

Additional range

In the southern part of its range, this bird dwells in pine-oak woods, and redwood forests with alders and willows understory. It is also found in oak woods and along stream-bordered willow groves.

Bird feeders

When visiting bird feeders, the chestnut-backed chickadee often consumes sunflower seeds, suet, and peanut butter mixtures, which are commonly provided by bird enthusiasts to attract various bird species.

What does a chestnut-backed chickadee sound like?

The chestnut-backed chickadee vocalizes with a unique mix of sounds, often shriller and faster than other chickadees.

How to tell the Bushtit from the Chestnut-Backed Chickadee

Visual differences

The Bushtit is smaller, measuring 3 3/4-4 inches long, with a modest color palette of black, brown, gray, tan, and white. It has a small bill and a long, wedge-shaped tail. The Chestnut-Backed Chickadee is slightly larger, about 4 1/2-5 inches long, and boasts a unique chestnut back and sides with a sooty brown cap and gray wings. The chickadee has a more pronounced bill relative to its size. Visual identifiers include the Bushtit's eye color difference by sex and the chickadee's consistent coloration across genders.

Key differences and behavior

Bushtits and Chestnut-Backed Chickadees showcase distinct behaviors that aid field identification. Bushtits are exceptionally social, traveling in large flocks and constantly communicating with bell-like calls. They thrive in a variety of wooded habitats, venturing into well-wooded suburbs, unlike chickadees who prefer dense coniferous forests. Bushtits, forming pairs post-winter, construct hanging nests intertwined with spiderwebs, while chickadees, potentially monogamous, opt for cavities often padded with fur. In terms of diet, bushtits mainly consume insects, occasionally eating berries and seeds, and seldom visit feeders. Conversely, chickadees have a diverse diet of insects, seeds, and berries and frequently visit feeders for sunflower seeds and suet. These behavioral nuances provide distinctive ways to identify these birds beyond visual cues.
