By the third week of July, as we have over the last 26 years, we will begin ARCI’s annual synchronized aerial surveys of the largest pre-migration roosts of Swallow-tailed Kites, all in Florida. This protocol is designed to track trends in the U.S. population of Swallow-tailed Kites by systematically counting them when and where most of this population is concentrated at the start of their southbound journey. These photographic counts tallied 6,741 individual kites at the peak of last year’s roost season. This year, for the first time, ARCI has secured enough funding to do the job more thoroughly than ever, thanks to contributions from a consortium of Florida zoos that feel strongly about supporting conservation: The Florida Aquarium, Jacksonville Zoo and Gardens, and the Brevard Zoo.

In addition, our kite telemetry project now has a new tagged bird, which Gina Kent captured in short order near a nest with recently-fledged young on Hillsborough County’s Bullfrog Creek Scrub Nature Preserve. This effort was made possible by the generous support of friends and volunteers of The Florida Aquarium and beyond, all due to the enthusiastic efforts of Glory Moore. Furthermore, Jenn Coulson successfully tagged two additional kites, one along the Strong River in Mississippi and another near Lacombe, Louisiana. Thanks to all for bringing our current sample of tracked kites up to nine with the addition of “Bullfrog”, “Strong River” and “Lacombe”!

We will begin posting updates soon on 2015’s southbound Swallow-tailed Kite migration. You also will be seeing reports on other exciting work ARCI is doing in Florida and the Caribbean:
- Adding another nine satellite-tracked White-crowned Pigeons, in Puerto Rico and southern Florida, to our collaborative range-wide project examining seasonal movements, threats, habitat use, and survival (these new tagging efforts thanks to Puerto Rico’s Department of Natural and Environmental Resources and Florida Fish and Wildlife Conservation Commission).
- Expanding our satellite-telemetry study of Reddish Egrets northward beyond the Keys by deploying three more GPS-equipped transmitters on birds in Ding Darling National Wildlife Refuge, as well as the first study of prey selection and abundance for this species (with generous funding and in-kind support from the Ding Darling Wildlife Society, Sanibel-Captiva Audubon Society, an anonymous donor, and the Refuge).
- Beginning new research on the potential occurrence of an insidious disease in Snail Kites, which may be affecting this Endangered species on the central-Florida lakes where most of its nesting effort now occurs (we thank The Bailey Wildlife Foundation for funding this project).
- Joining with Microwave Telemetry, Inc. (MTI), the Jost van Dykes Preservation Society, and the University of Roehampton (UK) to deploy solar-powered satellite transmitters on Roseate Terns in the British Virgin Islands (with major support from MTI and the Darwin Initiative). This species is endangered and declining throughout its western North Atlantic range, yet migration, stopover, and wintering areas are poorly known. The two terns we recently tagged represent the first use of MTI’s ground-breaking 2.2-gram transmitters, which are the smallest satellite-tracking devices ever produced, only half the weight of the next-largest satellite transmitter and 2% of a Roseate Tern’s body mass (the safe limit is considered 3%). If all goes as planned, we will expand this important study over a larger portion of the species’ breeding distribution in the coming year.
Correction: An earlier version stated we are tracking ten kites. The correct number is nine.
