|Migratory paths of seven Swallow-tailed Kites GPS tracked from breeding locations in the U.S to wintering locations in Brazil and Bolivia.
Bullfrog is near two big rivers in eastern Mato Grosso do Sul, the Rio Correntes and Rio Ápore.
Panther is 170 miles to the south-southeast of Bullfrog, near the town of Água Clara.
|Winter locations for seven GPS-tracked Swallow-tailed Kites in South America, November 2016.
It is amazing to see that birds from scattered breeding areas - in this case Louisiana, South Carolina and Florida - end up wintering together on the exact same farms over 5,000 miles from their nest sites!
Sawgrass migrated along a more westerly path through Bolivia. Her last location was on the Argentinian border in a location where we have not seen our GPS-tracked birds go before. Sawgrass is one of three Swallow-tailed Kites that we tagged with cell-phone (GSM)/GPS tracking devices, which we had not previously used. The other four tracked kites are carrying satellite/GPS units.
Carlton (another of the three kites with GSM/GPS devices) is a bit of a mystery. We last received data from him in early September while he was near the Panama/Colombia border. We hope that his transmitter will soon be detected by the cell-phone system and reveal where he has been. Migration is the most demanding and dangerous part of the Swallow-tailed Kite’s annual cycle. We hope that this bird has successfully completed its southbound journey and has found a safe place to spend the northern winter.
