Rankin Migration - 14 Nov. 2009

Having travelled about 6300 miles in 53 days (700 additional miles this week) and 6000 miles (970 additional miles this week) in 52 days, Blue and Red (respectively) reached the Equator this week and appear to be headed for wintering locations somewhere in the western South American.

East to west the birds are separated by the Andes with Blue having remained on the eastern side, while Red has used a more-or-less coastal route on the western side of the Andes. North to south, however, Blue is only 30 miles further south than is Red despite significant passage of time and distance.

As of the last update Red flew south from the Caribbean Sea on the Panamanian coast stopping briefly on the coast of the Gulf of Panama. It’s not unusual for peregrines to cross large bodies of water like to the Gulf of Mexico or in this case the Gulf of Panama over to Colombia…what is a little usual is the route that he took – he flew 275 miles south through the Gulf of Panama into the Pacific Ocean, then made a “U turn” and flew 150 miles back towards where he’d come from ultimately turning southward once again coming ashore in Colombia 106 miles later.
While it is possible that he found a boat or buoy on which to rest, the data indicate that he was airborne for 26 hours and covered more than 530 miles.

More next week.
