Relationship Between the North Atlantic Oscillation and spring migration phenology of Broad-Winged Hawks (Buteo platypterus) at Hawk Mountain Sanctuary, 1998-2013

Climatic factors influence migration behavior in both short- and long-distance migratory birds. The Broad-winged Hawk (Buteo platypterus) is a long-distance migrant that exhibits a regular calendar-like migration pattern, with some interannual variability during both the northbound and southbound mi...
