Ellen Zimmerman reported the return of the first Osprey - April 6th on a nest just south of Golden along the highway. Osprey in the Columbia Valley can travel over 6,000 km on their return flight from their wintering grounds. 
Telemetry studies using satellite transmitters tracked Osprey from southern BC to their wintering sites in  Mexico, Costa Rica, Panama and Venezuela.

Satellite telemetry of ospreys tagged in BC showing migration routes to wintering sites on the Pacific Coast of Mexico and in Central and South America.
