The females incubate the eggs, and the males bring them food. Most Bluebirds lay between five and seven eggs per clutch. Reproduction of the BluebirdĮxact breeding behavior varies slightly based on the species. Males fight aggressively over their nesting territories. Outside of the breeding season, most of them are quite social and congregate in large flocks.Īs the breeding season arrives, they establish their own territories, and are quite intolerant of neighbors. Their social behavior varies by species and season. These birds are diurnal, or active during the day. Zookeepers feed them a variety of different foods, including seeds, berries, fruits, nuts, mealworms, crickets, insect larvae, and pelleted insectivore diet. Most of the Bluebirds in zoos live there because they became injured and could no longer survive in the wild, or because they were born there. They are beautiful birds, and make for popular aviary inclusions. In zoos, these birds thrive in large enclosures or aviaries. In most places, it is illegal to own any of the three Bluebird species as a pet. Even though they are beautiful birds, they do not do well in a household setting. Humans have not domesticated Bluebirds in any way. The IUCN lists the Eastern Bluebird as Least Concern, the Western Bluebird as Least Concern, and the Mountain Bluebird as Least Concern. However, humans provide them with nest boxes and birdfeeders, both of which they utilize to help them survive. Human introduction of non-native species also causes population decline. Habitat destruction does impact them, especially the removal of dead trees where these birds nest. Humans impact these birds in various ways. Most Bluebirds hunt for prey along the ground, in the air, or in small shrubs and bushes. Some of the different types of insects and invertebrates that they catch include spiders, ants, snails, grasshoppers, wasps, caterpillars, flies, and more. While they are breeding, their diet primarily consists of insects, and during the winter they feed on seeds, nuts, fruits, and berries. These birds are omnivores, and they feed on both plants and small invertebrates. Finally, the Eastern lives throughout the eastern United States to New Mexico, and south into parts of Mexico and Central America. Westerns live throughout the western United States into Mexico. During the winter they migrate south through the rest of the United States into Mexico. Mountain Bluebirds breed from Alaska through western Canada and the northwest United States. Distribution of the BluebirdĮach species has a different distribution. They also thrive in areas close to humans, like pastures, farms, parks, gardens, and backyards. Some of the different types of ecosystems that these birds utilize include savannas, open woodlands, forest edges, clearings, meadows, prairies, and more. While the different species have different habitat preferences, they usually live in similar habitats to one another. Naturally, they nest in abandoned woodpecker holes, but nowadays many of these birds nest in manmade nest boxes.Īll three species of these birds prefer living in open areas rather than dense forest.
