Clay-colored Sparrow

A May 2017 Clay-colored Sparrow from Carleton College’s arboretum. This bird breeds across the Great Plains of the United States and Canada. Grant and Knapton (2012) write, “The Great Plains is the continent's most endangered major ecosystem. The decline in extent and quality of North American prairies coincides with decreasing populations of many bird species that depend on them, including the Clay-colored Sparrow.” Most forms of habitat destruction are fairly clear. Not so obvious is fire suppression, which allows a variety of invasive bushes to survive in the prairies.
