Rankin Migration - 06 Nov. 2009

Here's a synopsis of the entire migratory route for both birds, and below is one of their respective routes in Central America and northern South America.
Over the last week, Blue covered another 450 miles bringing his total to over 5550 miles. As most of the Rankin band returns have been from Brazil, I expected his route to continue south easterly. He has done the opposite and has headed west toward Bogotá and the eastern foothills of the Andes. The image below shows a GE version of a location on an escarpment over looking a river valley near Villanueva, Columbia where he spent 16 hours – it’s pretty easy to imagine the relative ease with which he could likely fly down and capture prey from that vantage point
… and this Panoramio image was embedded in GE 2.5 miles from his roost location – pretty nice habitat.
Red hugged the Costa Rican and Panamanian coastline on the Caribbean Sea fro an additional 425 miles for a total of nearly 5000 miles. His most recent data point shows that he has changed direction abruptly and has headed south bringing him a location near Picacho Mountain and within 10 miles of the Gulf of Panama.
The Panoramio image (below) was embedded in GE 0.5 miles from his roost location – pretty nice habitat too!
