Barn Swallow
Influence of climate on annual survival of Barn Swallows (Hirundo rustica)
Migratory Connectivity plays a role in survival for populations! “Climatic conditions on both breeding and wintering grounds likely affected the survival of these Seattle-breeding birds. By contrast, annual survival of swallows breeding in southern Ontario, Canada, remained constant over time and were not affected by any of the climatic parameters studied.”
