TextPublication details: MB : 1978.Description: 62 p. : map ; 28 cmOnline resources: Abstract: The main objective of this study was to monitor the nesting effort and success of Greater Canda geese (Branta canadensis maxima) using natural and artificial nest sites at Oak Lake, Manitoba. A secondary objective was to obtain information as to mortality causes and locations, and the effect of hunting pressure on the Oak Lake flock through band recovery analysis. It was hoped that through analysis of these variables, factors limiting the population's increase could be established and recommendations made to allow the population to reach its estimated optimum density. Aerial and ground surveys were conducted during the months of May and June, 1978. Band recovery analysis and calculations leading to an estimate of the optimum breeding density at Oak Lake were conducted. Results of aerial and ground surveys showed that a minimum of 33 nests were initiated in the Oak-Plum Lakes district. A minimum of 98 goslings reaching four weeks of ages was estimated from nest re-checks and mortality
