Data for: Ruffed grouse roosting behaviour

Behavioural flexibility is an important way in which animals respond to changing environmental conditions. During winter, snow cover is an important seasonal refuge that provides thermal insulation and protects overwintering species from predators. However, snow depth and quality can be highly variable throughout winter, and it is unclear how species that use snow cover adjust their behaviour with changing winter conditions and in complex landscapes. During winter months, Ruffed Grouse Bonasa umbellus spend a large portion of time roosting in trees, understory, and in some cases, subnivean environments. Importantly, the ability to snow roost has been associated with reduced stress levels and increased overwinter survival. Across three winters, we studied the plasticity of roosting behaviour across a diversity of winter conditions and land cover types. In line with predictions, grouse were more likely to use snow burrows when snow was deep and powdery, and experienced warmer temperatures...
