Abstract: Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered...
Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska–Siberia (WA–S), Northern Canada–Nunavut (NC–N), West-central Canada–Interior Alaska (WC–A) and East-central Canada–Minnesota (EC–M). WA–S and NC–N cranes primarily are composed of the lesser sandhill crane (A. c. canadensis) subspecies that breeds in the arctic, whereas WC–A and EC–M cranes are composed primarily of greater sandhill cranes (A. c. tabida), birds which breeds in northern parts of temperate...
