Shadow & Rainbow Head South

I am continually impressed with the information gathered from tracking devices on birds- remember the study that documented GPS-equipped Bar-tailed Godwits flying nonstop from Alaska to New Zealand?  Or how about the more recent discovery of Black Swift wintering territory in NW Brazil using light-level geolocators?

Currently, Rocky Mountain Bird Observatory is tracking two Osprey on their travels from the mountains of Colorado to warmer climes this fall.  From Jason Beason, RMBO’s Special Monitoring Projects Coordinator:

Greetings,

On June 19th, 2013 biologists from the National Park Service and Rocky Mountain Bird Observatory placed satellite transmitters on two female Osprey near Grand Lake, Colorado. We have been receiving data ever since from Argos (the company that owns the satellites) showing their locations. We named the Osprey “Rainbow” and “Shadow” because they nested at Rainbow Bay on Lake Granby and at Shadow Mountain Reservoir. Shadow began to migrate on September 15th and Rainbow on September 21st. If you are interested in seeing the migration of these two Colorado Osprey please click on the links below:
