Following the 2009 publication, “Filling a Void: Abundance Estimation of North American Populations of Arctic Geese Using Hunter Recoveries”, Lincoln estimates of total population size, which are derived from harvest and band-recovery data, start becoming more commonly used as a method to monitor and assess Arctic goose populations. For midcontinent snow geese and Ross’s geese, Lincoln estimates are substantially larger than counts from midwinter or photo-inventory surveys, sparking discussions among managers about the true size of these populations.
