Paper Documents Longest-lived Osprey Carrying a Transmitter

A paper published in the Journal of Raptor Research describes movements of a satellite-tagged osprey that nearly set a longevity record. An adult male osprey carrying a backpack satellite transmitter was found electrocuted at a utility pole in April 2016. The osprey was originally trapped and fitted at its nest on the Columbia River, ten miles downstream of Portland, Oregon in June 1996. He was electrocuted near the same nest when he was at least 22.83 years old—just 2.34 years short of the North American longevity record for osprey, and set the record for longest-lived osprey carrying a transmitter. This and other observations related to trapping adult osprey at their nests provide useful information to evaluate possible effects on ospreys trapped and fitted with backpack transmitters.
