Abstract: | Aspects of the breeding biology of a southern (58°N) and northern (71°N) population of Calidris pusilla were compared and related to climatic difference between the two areas. Snow melt was later and summer temperatures lower in the more northerly area. These harsher weather conditions may have influenced breeding biology, since birds in the more southerly area seemed under less strict energetic regimes, and bred at higher densities and earlier ages than those in the north. Nevertheless, peak nest initiation occurred on the same date in both areas. |
