Climate change and habitat management implications for a declining grassland songbird in the North American Great Plains

Accelerating climate change is affecting species worldwide, and is expected to have impacts on more than half of North American bird species. Some of the most rapidly declining birds in continental North America include those in the Great Plains, which are considered particularly vulnerable to climate-induced range contractions and shifts. Although grassland bird responses to habitat management are well-documented, less is known about their population responses to climate change and its interactions with their breeding habitat. We evaluated how climate and habitat management parameters influenced the abundance of Grasshopper Sparrow (Ammodramus savannarum), a declining Neotropical migratory…
