Types of Small Blue Birds
Bluebirds are a delightful group of small birds known for their vibrant blue feathers. In this section, we will explore three different species of small blue birds: the Eastern Bluebird, the Mountain Bluebird, and the Indigo Bunting.
Eastern Bluebird
The Eastern Bluebird (Sialia sialis) is a charming bird that can be found across eastern North America. With its stunning blue plumage, rusty-red breast, and white belly, the Eastern Bluebird is a sight to behold. These birds are cavity nesters and can often be found nesting in tree hollows or specially designed nest boxes.
Eastern Bluebirds are primarily insectivorous and feed on a variety of insects, including beetles, grasshoppers, and spiders. They are also known to supplement their with small fruits and berries when available. Eastern Bluebirds are highly territorial and will fiercely defend their nesting sites.
Mountain Bluebird
The Mountain Bluebird (Sialia currucoides) is a beautiful bird that inhabits the mountainous regions of western North America. While not as vibrant as the Eastern Bluebird, the Mountain Bluebird is still a stunning sight with its icy blue plumage and white underparts.
Unlike the Eastern Bluebird, Mountain Bluebirds are primarily insectivorous and rely heavily on insects such as beetles, caterpillars, and grasshoppers for their . They can often be seen perched on fence posts or low branches, scanning the ground for their next meal.
Mountain Bluebirds are known for their unique courtship displays, where the male performs a series of aerial acrobatics to attract a mate. They are also cavity nesters and will readily use nest boxes if provided. These birds are highly adaptable and can be found in a variety of habitats, including open grasslands, sagebrush plains, and mountain meadows.
Indigo Bunting
The Indigo Bunting (Passerina cyanea) is a small songbird found in North America. While it may not be as well-known as the Eastern or Mountain Bluebird, the Indigo Bunting is no less captivating with its brilliant blue plumage.
During breeding season, male Indigo Buntings are a vibrant blue, while females and juveniles have more muted brown feathers. These birds prefer brushy habitats, including woodland edges and overgrown fields.
Indigo Buntings primarily feed on seeds, especially during the winter months when insects are scarce. They have a unique feeding behavior called “gleaning,” where they pick seeds directly from the plant’s surface. In addition to seeds, Indigo Buntings also consume small fruits and berries.
During courtship, male Indigo Buntings sing melodic songs from high perches to attract females. They are monogamous and will defend their territory vigorously. Indigo Buntings build cup-shaped nests in dense shrubs or low trees, using grasses, leaves, and other plant materials.

The songs serve as a way for males to advertise their presence and territory, as well as to communicate their readiness to mate.
Nest Building
Nest building is an essential aspect of courtship and mating behavior in small blue birds. The male birds take on the primary responsibility of constructing the nest, while the females assess the quality of the nest before choosing a mate.
The nest building process starts with the male selecting a suitable nesting site. This can be a natural cavity in a tree, a nest box, or even a hole in a fence post. Once the site is chosen, the male begins collecting materials such as twigs, grass, and feathers to construct the nest.
The male blue bird meticulously arranges the collected materials in a cup-shaped structure, creating a cozy and secure environment for the female and future offspring. The quality of the nest is an important factor in attracting a mate, as it demonstrates the male’s ability to provide a safe and comfortable home.
Monogamy vs. Polygyny
Small blue birds display different mating strategies when it comes to monogamy and polygyny. Monogamy refers to the practice of forming a pair bond with a single mate, while polygyny involves mating with multiple partners.
Eastern Bluebirds are known to be monogamous, forming strong pair bonds that last throughout the breeding season. Once a pair bond is formed, the male and female work together to build the nest, incubate the eggs, and raise the offspring. Monogamy provides stability and ensures both parents contribute to the survival of their offspring.
On the other hand, Mountain Bluebirds and Indigo Buntings exhibit polygynous behavior. Male birds in these species may mate with multiple females, often simultaneously maintaining multiple nests. This behavior increases the male’s chances of passing on his genes and ensures genetic diversity within the population.
Polygynous males are responsible for attracting and courting multiple females, as well as providing for their offspring. This mating strategy can be energetically demanding for the males, but it increases the likelihood of passing on their genetic traits to future generations.
