5203 |a"We estimated minimum numbers of nesting birds in the known colonies of the Mid-continent Population of Lesser Snow Geese (Chen caerulescens caerulescens) and Ross’s Geese (Chenrossii), using aerial photography supplemented with ground surveys, in the Eastern Canadian Arctic in June 1997 and the Central Canadian Arctic in June 1998. We estimated 3,075,000 nesting Snow Geese in the Eastern Arctic (a 2.7-fold increase since the previous survey in 1979-80), and 740,600 nesting Snow Geese in the Central Arctic (a 7-fold increase since the survey in 1982). Thus, our minimum estimate for the Mid-continent Snow Goose Population in 1997-98 (Eastern + Central Arctic) was 3,815,600 nesting adults, which was an over 3-fold increase from the estimates for 1979-80 Eastern Arctic plus 1982 Central Arctic"--Abstract, p. i.
