General Description

You’ll easily recognize the Mountain Chickadee by its distinct white eyebrow, black cap, and agile movements among high tree branches. Found mainly in mountain forests, this small bird’s active foraging and rapid wingbeats are characteristic behaviors.

Physical Characteristics

The Mountain Chickadee is a tiny bird, often likened in size to a sparrow. This energetic flitterer sports a distinctive look, with:

A black cap and bib, offset by a prominent white eyebrow.
A white underbelly, with buff/gray sides and flanks.
Olive-brown upper parts, including wings and tail.
A preference for coniferous forests, where they’re often found foraging high in the trees.

Behavior

Mountain Chickadees are social flocks, often found in groups of up to three pairs of adults with a mix of young birds. They’re vocal, energetic, and acrobatic, clinging to small limbs and twigs or hanging upside down from pine cones.

They’re also quick and agile, hopping and flitting through the outer twigs in their search for insects and seeds.

In the summer, they band together, and in winter, they flock with kinglets and nuthatches.

Habitat

Mountain Chickadees are prevalent in the conifer forests of the mountainous West, especially in higher altitudes. They’re often found in dry coniferous forests, including pine, spruce, fir, and Douglas-fir. They’ve a preference for Ponderosa and lodgepole pines.

During the summer, they’re also seen in high-elevation aspen forests. In winter, they may occupy lower habitats like juniper stands, pine-oak, or pinyon-juniper. They occasionally wander to lowlands, taking advantage of planted conifers.

Nesting

You’ll find that the Mountain Chickadee typically places its nest in a hole in a tree, often occupying cavities in conifers or abandoned woodpecker holes. The female builds the nest with some help from the male, lays 7-9 eggs, and incubates them for about 14 days, with the young fledging approximately three weeks after hatching.

Nest Placement

Mountain chickadees are cavity nesters, and they prefer to nest in pre-existing cavities in coniferous forests at elevations of 6,000-11,000 ft. They seldom pick cavities with entrances much larger than their body diameter. They may also nest in wooden, sawdust, or concrete nest boxes.

Here are some additional details about their nesting behaviour:

They’re monogamous and territorial during the nesting season.
Breeding territory is about 6.5 hectares.
They may give a "snake display" when an object is inserted into the cavity or when a human approaches.
They’ll not return to a failed nest site but may reuse successful sites in subsequent years.
The female roosts in the nest cavity from the building of the nest until the nestlings are fully feathered.
Nest construction begins less than a week before laying, and the base is made of rotten wood chips, lichen, moss, grass, and fur.
They lay 7-9 eggs, and only the female incubates them.
Incubation takes around 14 days, and the nestlings fledge in about 18-21 days.

Nest Description

Mountain Chickadees are precise nest builders. The female constructs a soft cup from fur, bark fibers, moss, hair, feathers, and also creates a fur plug to cover her eggs when she’s away. They often fill large cavities with insulating material. Here’s a quick overview of their nesting behavior:

Feature	Description
Nest Materials	Fur, bark fibers, moss, hair, feathers
Nest Site Selection	Natural cavities, old woodpecker holes, cavity enlarged/excavated by chickadees, nest boxes
Nest Height	5-25′ above the ground

They’re also quite adaptable, sometimes nesting in stumps just a few inches off the ground or even in holes on the ground.

Eggs & Incubation

Mountain Chickadees lay white eggs, sometimes dotted with reddish-brown speckles. Their eggs are ovate with a smooth shell and little to no gloss.

The female typically lays one egg per day, and the average clutch size is 5 to 9 eggs, with an incubation period of 11 to 14 days.

During this time, the male feeds the female, and this division of labor continues after the eggs hatch, with the female brooding the young while the male brings food.

Food

The Mountain Chickadee primarily feeds on insects, spiders, seeds, and suet during the warmer months, actively foraging through tree canopies. In winter, it relies heavily on stored seeds, especially pine seeds, and visits bird feeders to supplement its diet.

Diet

Mountain Chickadees are active foragers, gleaning foliage for food. Their diet consists of:

Insects: beetles, caterpillars, wasps, aphids, leafhoppers, and more.
Seeds: from cones, and sunflower seeds from feeders.
Nuts: pine nuts.
Other food sources: spiders, larvae, and suet.

They have a daily caloric intake of about 10 calories and store food for later consumption.

Winter Diet

During the winter, Mountain Chickadees rely on food sources they’ve stored, like seeds from conifer trees, to survive. They’re often found in the high branches of conifers, foraging for insects and seeds, and will also come to bird feeders for seeds and suet.

Winter Diet	Food Sources
Seeds	Conifer trees
Insects	Bird feeders
Suet	Stored food

Mountain Chickadees are highly adaptable and will adjust their diet based on what’s available.

Conservation

You need to be aware that the Mountain Chickadee faces threats from habitat loss and climate change, which are contributing to its decline. Conservation efforts include protecting habitats and providing nest boxes to support their populations.

Threats

While the mountain chickadee is still widespread and common, surveys indicate declines in some areas. Threats to the species include habitat loss, increased fire frequency, and changes in insect prey due to climate change. These factors can also affect other wildlife and people.

Conservation Efforts

Conservation efforts for the Mountain Chickadee include:

Protecting their habitat, especially old-growth forests with natural cavities and plenty of insect prey.
Providing nest boxes, which can be effective if placed in habitats with access to quality food or shelter from predators.
Encouraging the use of bird feeders, as they’re frequent visitors and can benefit from the extra food source.

Fee-bee Song

The Mountain Chickadee’s song is a sweet, whistled "fee-bee," with the second note lower in pitch than the first. This two- or three-tone whistle is quite distinct from its "chick-a-dee-dee" call. The "fee-bee" song is often heard in the late winter and spring, and it serves to announce territorial boundaries and attract mates during the breeding season.

Here are some interesting facts about the Mountain Chickadee’s "fee-bee" song:

It’s a tricky song to hear in the wild, as it blends into the soundscape.
The song may include more than one "fee" or "bee," and occasionally, a couple of extra notes.
It’s one of the easiest bird songs to recognize and learn.
It’s used to communicate with other chickadees and signal territorial boundaries.
The Mountain Chickadee’s song is quite different from the Black-capped Chickadee’s, which is higher-pitched.

Fun Facts

Mountain chickadees have a daily caloric intake of about 10 calories and store food like sunflower seeds for later use. These birds consume large amounts of insects, especially during outbreaks, showcasing their adaptability in their habitat.

Caloric Intake

Mountain Chickadees have a daily caloric intake of about 10 calories, which is equivalent to around one-twentieth of an ounce of peanut butter.

They feed almost constantly during daylight hours, consuming insects and spiders in the summer and seeds and nuts in the colder months.

During outbreaks of tree-killing insects, they’ll feast on these pests, with one chickadee found to have 275 caterpillars in its stomach.

Food Storage

Mountain Chickadees are smart little birds with incredible memories. They cache food for the winter, hiding it under tree bark, in pine needle clusters, and beneath the soil. They’ve several hundred storage sites, each with a single food item, and they can remember where they’ve cached their food.

Insect Consumption

Mountain Chickadees are insectivores, and their diet mainly consists of insects during the warmer months. These include beetles, caterpillars, spiders, wasp larvae, aphids, leafhoppers, and more.

They play an essential role in controlling insect outbreaks in the evergreen forests of mountainous regions, dining on tree-killing insects like bark beetles and needle miners.

This bird’s survival is intimately connected to the health of these forests, as they rely on the insects and seeds the trees provide.
