Eastern Bluebird

♂ Eastern Bluebird, Sialia sialis
The Eastern Bluebird can be spotted throughout the eastern half of the United States, into the southern portions of Canada, and down through parts of Central America. They are often seen perched on wires, posts, or clear branches where they sit searching for prey. As mainly insectivores, this species plays an important role influencing insect community composition. A significant population decline during the 1930s was partially attributed to pesticide use, but also climate change, competition with non-native species, and habitat loss. Populations have since increased with help from nest boxes and better land management. The sky blue feathers of the male Eastern Bluebird have established this species as a good omen by groups such as the Navajo Indians.
