|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.

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.
