Located on the University of New Mexico main campus in Albuquerque, the Arid Lands Field Station is a satellite office of the Fort Collins Science Center, U.S. Geological Survey. Staff members work in Castetter Hall, home of the Biology Department.
A new paper in the journal Condor, authored by USGS scientists Janet Ruth, Robb Diehl, and others, describes how the authors used radar data and satellite land-cover data to identify the various habitats with which birds are associated during migration stopovers. Their results suggest that it is too simplistic to (1) consider the arid West as a largely inhospitable landscape in which there are only relatively small oases of habitat that provide the resources needed by all migrants; (2) think of western riparian and upland forests as supporting the majority of migrants in all cases, and (3) consider a particular habitat unimportant for stopover solely on the basis of low densities of migrants.
