Erica Spotswood nous en dit plus sur les risques de la capture par filets

The capture of birds using mist nets is a widely utilized technique for monitoring avian populations. While the method is assumed to be safe, very few studies have addressed how frequently injuries and mortalities occur and the associated risks have not been formally evaluated.
A team of American biolgists led by Erica Spotswood of the Department of Environmental Science, Policy and Management, University of California in Berkeley, quantified the rates of mortality and injury at 22 banding organizations in the United States and Canada and used capture data from five organizations to determine what kinds of incidents occur most frequently. Analyses focused on passerines and near-passerines, but other groups were included. They evaluated whether body mass, age, sex, mist net mesh size, month and time of day or frequency of capture are related to the risk or type of incident. They also compared the recapture histories over time between birds that were injured and those that were never injured for 16 species.
The results were published in 2011 in an article titled « How safe is mist netting ? evaluating the risk of injury and mortality to birds » in the Methods in Ecology and Evolution Journal.
