The Reddish Egret (Egretta rufescens), the rarest wading bird in the U.S., is a highly specialized feeder ecologically restricted to a very narrow coastal habitat that is vulnerable to human disturbance, storm effects, and climate change. The Florida population is estimated at 350-400 pairs, with 100-125 in Florida Bay and Keys. The latter sub-population appears to be steadily declining. In 2009, we began research based on satellite telemetry in the Florida Keys and are now expanding this study to include the Gulf and Atlantic coasts of Florida. Our results will address important management topics, including habitat and area needs, seasonal movements, site fidelity, breeding effort, survivorship, and sources of mortality. Telemetry data combined with direct observations suggest strong site fidelity with limited seasonal movements; highly competitive and aggressive foraging interactions; lower-than expected adult; and narrow habitat selection, which may further constrain this small resident population.
ARCI has collaborated with Tom Wilmers (U.S. Fish and Wildlife Service) and Stefani Melvin (formerly U.S. Fish and Wildlife Service). Our conservation partners include members of the Reddish Egret Working Group, with whom we are drafting a range-wide conservation strategy and management plan in cooperation with the U.S. Fish and Wildlife Service.
