Data for Paper: Population-wide failure to breed in the Clark’s nutcracker

(1) Data used to evaluate adult body condition. (2) Number of days we tracked each radio tagged bird (2010-2012). (3) Breeding years versus average environmental variables. For continuous measures of cone crop, snowpack and temperature, see third party sources: sources: Whitebark pine cone crop data was obtained from a third party and can be requested from the Interagency Grizzly Bear Study Team (http://www.nrmsc.usgs.gov/research/igbst-home.htm). Snowpack and temperature data are available online from the United States Department of Agriculture Natural Resources Conservation Service Togwotee Pass SNOTEL station (http://www.wcc.nrcs.usda.gov).
