Simply put, the Canada Goose<\/strong> is the most widely distributed goose species in North America. Its breeding range stretches from the arctic coastal plain of Alaska to the northern half of Florida, while its wintering range extends as far south as Baja California and northern Mexico (Mobray et al. 2020). Currently there are 12 known subspecies of Canada Goose, 2 of which occur in Florida: <\/span>Branta canadensis interior<\/span><\/i> and <\/span>B. c. maxima<\/span><\/i> (Mobray et al. 2020)<\/span>. <\/span><\/i>In the 1960s and 1970s, the FWC released several populations of <\/span>B. c. maxima <\/span><\/i>throughout the northern half of Florida for hunting purposes, and now these nonmigratory birds have established breeding populations in various counties including Leon, Alachua, Marion, Volusia, Santa Rosa, Manatee, Seminole, and Dade (Willcox and Giuliano 2006). Winter ranges of <\/span>B. c. interior <\/span><\/i>naturally<\/span> extend into northwestern Florida (Mobray et al. 2020)<\/span>. <\/span><\/i>There is also notable geographic variation within this species across its range, with body size decreasing from southeast to northwest (the opposite of Bergman\u2019s Rule), and plumage darkness generally increasing from east to west (Palmer 1976, Johnson et al. 1979).\u00a0<\/span>\u00a0<\/span><\/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\/2024\/11\/CANG_Pierce_1975.png” alt=”Line Drawing of Smooth-billed Ani by Diane Pierce.” title_text=”CANG_Pierce_1975″ _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=”75.2px” 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> Walters, M.

Because Canada Geese are primarily grazers, with bills designed to tear blades and strip seeds from grains, they also prefer areas with abundant grass (Willcox and Giuliano 2006). In addition to prairies, parklands, coastal plains, tundra, and high elevation meadows, Canada Geese are also quite common in suburban and urbanized areas, such as parks and golf courses, where they are often seen in Florida.\u00a0<\/span><\/p>\n Results from the BBA II show that confirmed Canada Geese detections are most heavily concentrated in Leon, Duval, Clay, and Manatee counties, with Seminole, Orange, and Marion counties showing several probable detections (Figure 1). Notable areas of population increase, compared to BBA I, include Jacksonville, St Petersburg, Clearwater, and Orlando, as well as the Florida Panhandle (Figure 2). Compared to a mere 20 confirmed breeding detections in BBA I, Canada Geese have now been confirmed in 39 quads for BBA II, bringing the total number of quad detections across all breeding code types from 26 to 79 (Table 1).<\/span>\u00a0<\/span><\/p>\n Despite the now common knowledge that 3 billion birds have been lost in North America since the 1970s, waterfowl, including the Canada Goose, are a notable exception to this troubling trend (Rosenberg et al. 2019). According to the BBS, the Canada Goose is experiencing a survey-wide estimated trend of 7.3 (95% CI = 4.1 \u2014 9.1; <\/span>n<\/span><\/i> = 3,174) and 7.8 (95% CI = 0.8 \u2014 15.3; <\/span>n<\/span><\/i> = 14) in Florida (Sauer et al. 2020; Figure 3).\u00a0<\/span>\u00a0<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ fullwidth=”on” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_fullwidth_image src=”http:\/\/lib.usf.edu\/breeding-bird-atlas\/wp-content\/uploads\/sites\/66\/2024\/11\/CANG_AlexLamoreaux_CanadaGoose_Banner.jpg” alt=”Two adult and four juvenile Canadian Geese swim in grey waters” title_text=”CANG_AlexLamoreaux_CanadaGoose_Banner” admin_label=”Courtesy Alexander Lamoreaux” _builder_version=”4.18.0″ _module_preset=”default” min_height=”474.6px” box_shadow_style=”preset1″ box_shadow_vertical=”-4px” box_shadow_blur=”9px” box_shadow_spread=”1px” box_shadow_color=”#CBD2D8″ global_colors_info=”{}”][\/et_pb_fullwidth_image][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.18.0″ _module_preset=”default” background_color=”#CBD2D8″ custom_margin=”0px|||||” custom_padding=”6px|||||” global_colors_info=”{}”][et_pb_row module_id=”#Data” _builder_version=”4.18.0″ _module_preset=”default” min_height=”93.4px” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_id=”data” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.18.0″ _module_preset=”default” custom_margin=”-29px|auto|-32px|auto||” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”http:\/\/lib.usf.edu\/breeding-bird-atlas\/wp-content\/uploads\/sites\/66\/2024\/11\/CANG_WendyMeehan_CanadaGooseA-scaled.jpg” alt=”Canada Goose on green grass” title_text=”CANG_WendyMeehan_CanadaGooseA” _builder_version=”4.18.0″ _module_preset=”default” min_height=”381.8px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” custom_margin=”-20px|||||” global_colors_info=”{}”]Quad level comparison of BBA I and BBA II based on the highest breeding code observed for a species within the 6 blocks of each quad.<\/span><\/span> [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ admin_label=”figure 1″ module_id=”fig1-expanded” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” header_2_text_color=”#005432″ header_3_text_color=”#005432″ global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_image src=”http:\/\/lib.usf.edu\/breeding-bird-atlas\/wp-content\/uploads\/sites\/66\/2024\/11\/BBA2MaxQuad_CANG.jpeg” title_text=”BBA2MaxQuad_CANG” _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n Figure <\/span>1<\/span>. <\/span>Canada Goose<\/span> quad-level distribution, Florida Breeding Bird Atlas II.
