Various raptors fly over Panama as part of their migration highway. Here each Fall we get to experience a small portion of this migration as part of or our day to day voyeurism.
In the Fall of 2004, the first intercontinental migration count of raptors was completed along the Panama Canal. They counted the birds ocean to ocean. Both professional and volunteer conservationists descended upon Panama to record the flight of over more than three million birds of prey. There are turkey vultures, broad-winged hawks and Swainson’s hawks in these migrations.
I cannot tell you how many of these same birds we had the opportunity to observe here in Bocas del Toro Panama but what I can tell you is that it is so cool to see. These large groups of big powerful birds fly together and then do acrobatics as they drift on a thermal.
“An ocean-to-ocean count of raptors traveling through central Panama has long been the ‘Holy Grail’ for raptor-migration scientists and conservationists,” explains Dr. Keith Bildstein, Hawk Mountain’s director of conservation science. “Until now, the lack of human willpower and financial resources has forestalled this ambitious and important project.” In the Fall of 2004 they made the dream a reality.
The initial record of raptor migration in Panama was made by a Spanish historian named Gonzalo Fernandez de Oviedo, who, writing in1526 noted in the Darien of eastern Panama in “Some years in the month of March, I have seen over the space of 15 or 20 days . . . the sky covered with birds almost morning to night. . . They . . . cover the whole sky from north to south and a wide section east to west. Apparently most of these birds are eagles and many large species of other birds of prey.”
Raptors fly only during the day and then only during good weather. So they require safe havens for nighttime and rainy day roosting. The Bastimentos National Marine Park includes protected forest which gives these birds a refuge and resting place during their migration.
