Handling stress of female common eiders during avian cholera outbreaks
Abstract Researchers often consider the importance of minimizing holding time during research activities; however, the long‐term costs of such handling stress is rarely measured explicitly. As part of an ongoing study of common eiders ( Somateria mollissima ) at a breeding colony in East Bay, Southa...

As part of an ongoing study of common eiders ( Somateria mollissima ) at a breeding colony in East Bay, Southampton Island, Nunavut, we recorded duration of restraint for females captured during avian cholera epizootics (2007 and 2008) and monitored female fates (breeding probability, onset of laying, and survival) relative to holding time.

In both years, longer restraint durations delayed onset of egg‐laying after capture by 0.5 days for each 10 min of additional restraint but did not prevent breeding. This delay of nest initiation did not enhance survival probability. Our results show that prolonged holding time can exacerbate mortality during epizootics and emphasize the importance of minimizing restraint time in wild birds, especially in the presence of diseases. © 2011 The Wildlife Society.
