Glossy Ibis
Plegadis falcinellus (Linnaeus, 1766)
Birds

Threats [-]
Degradation of breeding and foraging habitat is the greatest threat to Glossy Ibis (McCrimmon 2006). Other threats include flooding, development, disturbance of nesting areas by human activity such as boating, fishing, and dredge spoil deposition, and predation primarily by gulls, fox, and raccoons (New York Natural Heritage Program 2009).

Conservation Strategies and Management Practices [-]
Current and potential breeding, foraging, and wintering areas should be protected. Continue to develop and conduct management and habitat restoration plans along with state, local, and federal partners. Continue to monitor populations and discuss ways to improve survey methods. Compare state population trends against regional trends to determine population dynamics across various geographic areas and time periods. Consider developing and initiating a banding program to get a better handle on breeding populations and migratory patterns (McCrimmon 2006).

Research Needs [-]
In general, the Glossy Ibis is a poorly studied species. More information is needed regarding life history, breeding, and behavior (Davis and Kritcher 2000). Research is needed to identify key habitat characteristics necessary for breeding, foraging, and wintering areas. All potential threats should be identified including those created by human disturbance as well as predators, pathogens, and invasive species, and ways should be saught to diminish their impact (McCrimmon 2006).
