<br />',; <br />.,"",:,~ <br /> <br /> <br />Distribution <br /> <br />Historically, Piping Plovers bred across three geographic <br />regions: 1) U.S~ and Canadian Northern Great Plains from Alberta <br /> <br />to Manitoba, and south to Nebraska; 2) Great Lakes beaches; and <br /> <br /> <br />3) Atlantic coastal beaches from Newfoundland to North Carolina. <br /> <br /> <br />Winter sites were not well described, although Piping Plovers <br /> <br /> <br />were generally seen along the!Gulf of Mexico, on southern U.S. <br /> <br /> <br />Atlantic coastal beaches from North Carolina to Florida, in <br /> <br />eastern Mexico, and on scattered Caribbean Islands (Haig and <br /> <br />Oring 1985). <br /> <br />t <br /> <br />Currently, the species' r~nge remains similar to historic <br /> <br />range accounts except that Pip~ng PloverS breeding in the Great <br /> <br />Lakes have almost disappeared (Figure 1, Table 1, Haig and Oring <br /> <br />1988b). In 1986, northern Michigan had the only viable breeding <br /> <br />population of Piping Plovers in the Great Lakes area. Data on <br /> <br /> <br />wintering birds are so sparse it is difficult to determine if <br /> <br />loss of nonbreeding sites has occurred. Migratory routes have <br />not been described. <br /> <br />Historic Distribution <br /> <br />Historic distribution and census data are sporadic in some <br />regions or altogether lacking for others. COmprehensive <br />censusing efforts began after 1980. The information presented <br /> <br />here represents a summary of museum records and historic accounts <br /> <br />for the distribution of the species prior to 1980 (documented in <br /> <br />Haig 1986a). <br /> <br />4 <br /> <br /> <br />~ <br />
