ARCI began tagging Swallow-tailed Kites in 1996 with the smallest satellite transmitters yet produced and soon discovered that the U. S. population’s migration pathway was much different and ended much farther away - over 8,000 kilometers - than had been imagined. By 2005, we had combined this dramatic new remote-sensing technology with direct VHF radio tracking in South America to confirm consistent annual movements over Gulf and Caribbean waters, Mexico’s Yucatan Peninsula, eastern Central America, and around South America’s Amazon Basin to wintering sites in the heterogeneous landscape of southern Brazil and nearby Bolivia. In 2011, to identify year-round habitat needs and range areas, determine critical breeding areas, estimate annual survival, and investigate migration and wintering threats, we began deploying the smallest ever GPS-equipped satellite transmitters. These devices provide up to eight locations each day, accurate to within 15 meters, for several years. This collaborative project with Dr. Jennifer Coulson was made possible by funding from the U. S. Fish and Wildlife Service and by Microwave Telemetry’s unscheduled development of a satellite/GPS unit small enough to be carried by a Swallow-tailed Kite. Such data will enable us to refine management recommendations and intensify conservation efforts where most needed throughout the Swallow-tailed Kites year-round range.
