Climate Change and Shifting Altitude Ranges

Is climate change pushing birds to higher elevations than they've historically occupied? Are birds that live at the tops of mountains losing habitat as higher altitudes get warmer? This month, Ellie and Willson explore these questions as they discuss the paper "Altitudinal range shifts of birds at the southern periphery of the boreal forest: 40 years of change in the Adirondak Mountains" by Kirchman and Van Keuren (2017).
