Bluebirds are territorial and prefer open grassland with scattered trees. This is similar to the behaviour of many species of woodpecker. Bluebirds can typically produce between two and four broods during the spring and summer (March through August in the Northeastern United States)
Great Gray Owl (Strix nebulosa) is a very large owl, documented as the world's largest species of owl by length. It is distributed across the Northern Hemisphere. In some areas it is also called Phantom of the North, cinereous owl, spectral owl, Lapland owl, spruce owl, bearded owl, and sooty owl.
