Endemic to Mongolia, northeast China, and eastern Russia; migratory, and wintering in central and eastern China, Swan Goose<\/strong> is the common domestic goose of farms, zoos, and private collections now widely established from introductions in many areas of the USA (Carboneras and Kirwan 2020). The eBird occurrence map shows their distribution concentrated in numerous, mostly urban, areas where they are found generally associated with wetlands such as detention ponds and lakes (eBird 2022).<\/p>\n Swan Goose is classified as \u201cpresent, not established\u201d (FWC 2023), and all Florida records are classified as \u201cEscapees\u201d (eBird 2022), despite the large number of observations at sites ranging from urban parks to remote wetlands in much of central and coastal peninsular Florida (eBird 2022). During BBA II, atlasers recorded 8 breeding occurrences of geese of unknown origins ranging from the western panhandle (Okaloosa County), Duval County, south to Broward and Miami-Dade counties (Table 1, Figure 1). In comparison, during the first Florida Breeding Bird Atlas, Swan Goose occurrences were attributed to escapees from private collections or tourist sites and breeding birds were found in 2 quadrangles in central peninsular Florida:\u00a0 a confirmed and probable record in Pasco County, and a probable record in eastern Lake County (FWC 2003) (Figure 2).<\/p>\n Given the few records in Florida, Breeding Bird Survey (BBS) estimated trends are not included for Swan Goose (Figure 3 is not included in this account). The feral Swan Goose population in Florida is likely to continue to increase, with additional range expansion, where wetland habitat is available.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.18.0″ background_color=”RGBA(255,255,255,0)” background_enable_image=”off” background_blend=”lighten” background_pattern_repeat_origin=”center” custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_image src=”http:\/\/lib.usf.edu\/breeding-bird-atlas\/wp-content\/uploads\/sites\/66\/2023\/12\/SWGO_CaroleDevillers_SwanGeeseC_Thumb.jpg” alt=”Line Drawing of Smooth-billed Ani by Diane Pierce.” title_text=”SWGO_CaroleDevillers_SwanGeeseC_Thumb” _builder_version=”4.18.0″ _module_preset=”default” box_shadow_style=”preset1″ global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”|300|||||||” text_font_size=”14px” text_line_height=”1.5em” min_height=”38.2px” custom_margin=”||0px||false|false” custom_padding=”5px|8px|0px|8px|false|false” border_width_all=”1px” border_color_all=”#7E96A0″ global_colors_info=”{}”]<\/p>\n Citation:<\/strong> Hodgson, A.
