IMPLICATIONS OF CUTTHROAT TROUT DECLINES FOR BREEDING OSPREYS AND BALD EAGLES AT YELLOWSTONE LAKE.

The article focuses on a study which examines the relationship between an index of cutthroat trout abundance and spring weather on Osprey or Pandion haliaetus and bald eagle reproduction at the Yellowstone National Park (YNP). The steep declines in an index of cutthroat abundance, Osprey productivity and nesting success were documented. Results suggested the importance of cutthroat trout recovery for maintaining a breeding population of Ospreys but less important for Bald Eagle population.
