Expected shifts in the upper forest limit of many mountain ranges due to anthropogenic climate change will likely be constrained by current and historical land-use practices. We used historical maps and Landsat satellite imagery to analyze timberline

Perch-sites are a necessary component of Loggerhead Shrike (Lanius ludovicianus) foraging habitat, yet little is known about the influence of perch characteristics on perch use. We hypothesized that Loggerhead Shrikes would selectively forage from ta
