Abundance, movement and habitat use of Swainson's hawks in their wintering grounds, Argentina
(University of Florida, 2000)
Knowledge of habitat use by a particular species is necessary in developing species conservation plans. Large-scale mortality of Swainson’s hawks (Buteo swainsoni) in Argentina during austral summer 1995-96 identified the ...
Can a 'wintering area effect' explain population status of Swainson's hawks? A stable isotope approach
(Wiley Blackwell Publishing, Inc, 2008-07)
It has been suggested that declines in breeding populations of Swainson's hawks (Buteo swainsoni) in California, Oregon, and Nevada may be due to differential mortality of hawks on their wintering grounds. Although massive ...
