M
starts withAdults of both sexes have a black cap joining a black postocular stripe behind distinctive white eyebrows. Their backs and flanks are gray and they have paler gray underparts; they have a short black bill, and a black bib. The typical adult wingspan is 7.5 in (19 cm), and the overall length is 5–6 in (13–15 cm). The Mountain Chickadee is one of 55 species of Chickadees and Tits. The mountain chickadee can be distinguished from other North American chickadees because mountain chickadees have a solid black-cap, whereas all other North American chickadees are marked with a white line through the side of their black cap. Another difference between the mountain chickadee and the 55 other species of chickadees is their location, range, and habitat.
Common inhabitants of the mountainous regions of the western United States, their range extends from the southern Yukon to California and Rocky Mountain States in the United States. A few mountain chickadees may migrate locally up the mountains in the summer and down into the mountain foothills in the winter; but this phenomenon is not well documented.
The mountain chickadee’s behavior is pretty similar to other chickadee species. They are fast and agile birds that hop through twigs while looking for insects and seeds. When summer is coming to an end, the mountain chickadees group together with a couple adult birds and some young birds in each grouping. The young birds usually spend the summer on their own, but as winter comes around they meet up with the older birds.Recent studies have indicated that in mixed flocks, black-capped chickadees become dominant over mountain chickadees. They are also very active birds. They can be found grasping to small twigs, and often hang upside down.
Their primary diet is insects during the summer and breeding season; conifer seeds and other plant seeds are taken throughout the year. They cling to the undersides of branches and to tree trunks, searching for food in the bark or breaking seeds open by hammering them with their beaks. Mountain chickadees also eat a wide variety of insects. These insects include caterpillars, beetles, insect eggs, pupae, and spiders. They spend most of their daylight hours scavenging for food and feeding. Their diet is best categorized as omnivorous, with only 30 percent of their food being plants and the rest insects. Due to their insect-rich diet, Mountain Chickadees help to manage and control insect populations.
They breed monogamously, producing 1 to 2 broods per year. In each brood, the average clutch size is 5 to 9 eggs. The eggs are white, but are speckled with a terracotta color. Occasionally, the Mountain Chickadee will lay an egg without any terracotta color. Incubation by the female is 14 days. The young are altricial, and stay in the nest for 21 days while being fed by both parents.
Mountain Chickadees build their nests in cavities. It is common to find nests of Mountain Chickadees in wood, but since they cannot burrow into wood that is not softened, they also build their nests into pockets that are either naturally occurring or previously made by another species. Inside of the nest, the female Mountain Chickadee builds a seal for the entry from resources she gathers, such as fur. This functions as protection for her newly laid eggs when she leaves the nest. She also may use these resources to build insulation for her nest if the crevice is large. The average depth for a Mountain Chickadee nest falls between 13 to 27 centimeters. Mountain chickadees also may use a nest for multiple years. Mountain chickadee populations are often limited to certain locations which have good nesting sites and many cavities for inhabiting.
