Jim Gray ACKNOWLEDGEMENTS This plan is dedicated to the memory of Rich Paul. Nancy Douglass Plan Dedication The Reddish Egret Conservation Plan is dedicated in memory of Rich Paul (1946 – 2005), an outstanding field ornithologist, who conducted extensive research on the Reddish Egret during his career with National Audubon Society. He was the manager of the Coastal Islands Sanctuaries and in his younger days worked at Audubon’s research station in the Florida Keys. He wrote the first status assessment for the Reddish Egret in 1991 and coauthored the Birds of North America species account in 2002. In 1994 he was named Wildlife Conservationist of the Year by the Florida Wildlife Federation; a year later he received the Golden Egret Award, Audubon’s highest career service award. In 2001, the National Fish and Wildlife Foundation honored him with the Chuck Yeager Award for action and achievement. Acknowledgements Thanks go to many individuals from universities, private conservation organizations, state conservation agencies, and U.S. Fish and Wildlife Service offices (USFWS) that provided information used in developing this plan. We especially thank those who attended the Reddish Egret Workshop held in Corpus Christi, TX in October 2012 (see Appendix B for a list of participants). Completion of the plan would not have been possible without their guidance, support, and input. Jennifer Wheeler (USFWS), Clay Green (Texas State Univeristy), and Eduardo Palacios (Pronatura Noreste) provided day to day guidance and consultation during the completion of this project. Special thanks go to Stefani Melvin who established the Reddish Egret Working Group in 2005 and did much of the preliminary work for this plan.

Tom Grey EXECUTIVE SUMMARY Despite its large range, the Reddish Egret occupies a restricted belt of coastal There is nothing in habitat, is patchily distributed and has a relatively small and declining global which the birds differ population. Accordingly there is broad agreement that the Reddish Egret is in need of our conservation effort. Using the “Open Standards Approach for more from man than Conservation Measures” the Reddish Egret Working Group presents a range- wide conceptual conservation model for this species that highlights and ranks the way in which they the greatest threats to maintaining population stability and expanding the can build and yet population, explores the underlying causes of those threats, and identifies key strategies to address them. This document serves as a guide for conserving the leave a landscape as it Reddish Egret as a species throughout its range, proposing processes to identify focal colony sites and foraging areas, defined as the locations that should be was before. priorities for collective conservation effort. This plan also provides the context to ~Robert Lynd support management action for locally important locations. We recommend four over arching strategies: 1. Actively manage factors directly affecting Reddish Egret populations 2. Ensure that long-term stewardship and management of habitat is effectively implemented in focal colony sites and foraging areas 3. Develop and implement long-term monitoring of populations to support better decision-making at the local, regional and global scale. 4. Identify mechanisms for conserving unprotected focal areas. This plan emphasizes consideration of the way interventions will influence indirect and direct threats, and promotes activities to ultimately achieve the stated goals. Central to this process was compilation of current species information to identify focal nesting sites (Note: a colony implies nesting; a site is the physical space that can be occupied or not; a colony is always occupied, i.e., site + birds nesting) and foraging areas. Although this plan lists activities to address threats and proposes a list to calculate necessary investments, it is not a business strategy—yet. Next steps include further articulating activities, formulating metrics to measure success, assessing capacity and risk, and making this plan operational. It should be viewed as a milestone in an ongoing and evolving campaign by the Reddish Egret Working Group to restore and maintain viable Reddish Egret populations throughout the species’ range.

The global population of Reddish Egrets is estimated to be 5,000 – 7,000 To advance the conservation of this species, the individuals, with 3,500 to 4,250 breeding pairs (see Reddish Egret Working Group, a multi-organization Table 6). partnership with scientists and managers from U.S., Bahamas and Mexico was formed.

Matt Jeffrey Reddish Egret pair. Emily Whittman 2 | REEG CONSERVATION ACTION PLAN Several projects to fill information gaps identified in the Status Assessment were undertaken in subsequent years (Bates et al. 2009, Palacios and Green. 2010, Green et al. 2011, Hill and Green 2011, Fidorra et al. 2011, Holderby et al. 2012, Hill et al. 2012). Additionally the many organizations represented in the Reddish Egret Working Group continued to undertake management activities to survey, protect, and foster local Reddish Egret populations and habitats. Conservation plans were developed to guide local and regional action [e.g., the Texas Gulf Coast (Vermillion and Wilson 2009)] yet a range-wide plan was needed. This Conservation Action Plan was conceived as a means to ensure that further investments in Reddish Egret conservation were guided by a shared set of range- wide goals and prioritized to most effectively reach those goals. Moreover, this comprehensive framework will allow each stakeholder to understand the contributions and intended outcomes of each local

The availability of different habitat types, which varies from salt to freshwater and from open to forested wetland, allows the herons to segregateinto two groups (1) Great Blue Heron (Ardea herodias)-Great Egret (Casmerodiusalbus)-Snowy Egret (Egretta thula), that use mainly freshwater habitats, and (2) Reddish Egret (E. rr&cens)-Tricolored Heron (E. tricolor), that use marine habitats. We have no data for Boat-billed Herons (Cochlearius cochlearius),because this speciesis strictly nocturnal, and censuseswere conductedat day- light. Prey type and prey size greatly differ among Great Blue Herons, Great Egrets, and Snowy Egretsbut overlap considerablybetween the Reddish Egretsand Boat-billed Herons. We found a positive correlation between size of heron and size of prey, but in our study area prey size is not important in niche segregation,since four of these specieseat prey of similar sizes.

We implemented a statewide survey of nesting Reddish Egrets during the 2016 breeding season to estimate population size as a baseline for monitoring and to identify the largest breeding colonies to help prioritize management activities in Florida. We first prioritized potential breeding sites based on historical data, then used a combination of direct counts (i.e., counts performed by walking into a colony or by slowly circling a site in a boat), flight-line surveys (i.e., counting adults flying to and from breeding sites), and nonstandardized surveys to estimate the number of breeding pairs at 305 wading-bird breeding sites throughout Florida. Fifty-eight of the 305 sites surveyed (19%) had at least one nesting pair of Red- dish Egrets. Birds were fairly evenly distributed across identified core nesting areas, with 78-86 pairs in southwest Florida, 54-88 pairs in Florida Bay, 95 pairs in the lower Florida Keys, and 34-43 pairs in or near Merritt Island National Wildlife Refuge.

  • Heron Behavior Terminology
    The Terminology of Courtship, Nesting, Feeding and Maintenance in Herons James A. Kushlan (Cite as: Kushlan, J. A. 2011. The terminology of courtship, nesting, feeding and maintenance in herons. [online] www.HeronConservation.org) Each species of heron has a species-specific repertoire of behavior it uses. However among species, there is much communality and similarity. Some of this similarity is due to the behaviors being evolutionarily homologous although some may just be duo to constraints that a bird of a certain morphology in a certain place can do. During courtship these behaviors are used to attract, pair, and maintain contact with a potential mate. During nesting, these behaviors are used to build and maintain the nest and eggs. During foraging, various behaviors are used to catch and handle prey. Similarly herons have behaviors they use for maintenance. The behaviors and the repertoire for most species are often not clearly described or understood; and much additional descriptive research is needed. Because there is a significant communality among species in the behaviors each shows, a common set of terminology can be used to facilitate comparison and contrasts among or within species. The unified terminology for heron behavior is described below. Specific behaviors are shown in bold in the descriptions below. Those studying and describing heron behavior are urged to use this standard terminology. Due to advances in knowledge, the terminology does evolve over time and this evolution will be captured in the present document as it occurs.
