Mountain plover in Canada : surveys and records up to 2005 / Richard W. Knapton, Geoffrey L. Holyroyd and Helen E. Trefry. : CW69-5/448E-PDF
"The Mountain Plover (Charadrius montanus) was first classified as an endangered species in Canada in April 1987 (COSEWIC 2002a). It was so designated because of a perceived decline in range and abundance since the first mention of the species at or near the Canadian border along the 49th parallel by Coues in 1874 (fide Wershler and Wallis 1986). The classification of endangered was maintained most recently by COSEWIC following an updated status report of the Mountain Plover in 2000 (Wershler 2000). In this report we compile all known historical and modern records of Mountain Plovers in a comprehensive way allowing for a critical review of the species' historical and current status in Canada, we report on systematic searches conducted in 2005 and on surveys conducted in suitable habitat between 1998 and 2005, and make recommendations for future surveys"--Introd., p. 1.
