Yesterday, the ABA Checklist Committee (CLC) unanimously (8–0) accepted the Egyptian Goose (Alopochen aegyptiaca) as an established exotic in southeastern Florida (Martin, Palm Beach, Broward, and Miami-Dade counties). The CLC vote was in response to a 6–1 vote by members of the Florida Ornithological Society Records Committee (FOSRC) to add Egyptian Goose to the official Florida bird list as an established exotic. Evidence to support establishment was provided by a paper by Bill Pranty and Valeri Ponzo to be published later this year in Florida Field Naturalist; the final draft of the manuscript was shared with members of the FOSRC and CLC.
Using observations from January 2012 to December 2013, Pranty and Ponzo tallied 1,204 geese at 181 separate locations in the southernmost four counties along Florida’s Atlantic coast. The size of the occupied range is about 1,900 square miles, consisting primarily of residential developments, city parks, and golf courses. Egyptian Geese have been resident in Martin County, Florida since 1994 (Braun 2004), and 77 breeding observations were compiled throughout Florida, with most of these recent (Pranty and Ponzo 2014).
Egyptian Geese are native to sub-Saharan Africa and the Nile River drainage. Exotic populations, originating from birds released as ornamental waterfowl, are widespread in Europe, with a recent estimate of 26,000 pairs, including more than 11,000 pairs in the Netherlands (Gyimesi and Lensink 2012). Egyptian Geese are found elsewhere in the ABA Area, such as Arkansas, California, central Florida, Texas, and other places, but those populations are not established (Pranty and Garrett 2011, Smith and James 2012, Pranty and Ponzo 2014). Nonetheless, birders should document the occurrence of Egyptian Geese outside of southeastern Florida as part of an effort to monitor populations of exotic birds—whether or not “countable”—throughout the continent.
The Egyptian Goose is species #986 on the ABA Checklist, an increase of five species since the CLC’s most recent published annual report (Pranty et al. 2013). Zino’s Petrel was added in November 2013, and three species were added in July 2014 based on taxonomic “splits” accepted by the American Ornithologists’ Union Committee on Classification and Nomenclature—North and Middle America (Chesser et al. 2014): Salvin’s Albatrosses (split with Shy [now White-capped] Albatross), Ridgway’s Rail (split with Clapper Rail), and Kamchatka Leaf Warbler (split with Arctic Warbler).
