Nesting by Canada Geese on Baffin Island, Nunavut
Outside of northern Quebec, there is little evidence to confirm reports of nesting by Canada Geese in Arctic habitats of North America, but they nest regularly in the Arctic tundra of West Greenland, from about 62˚ N to as far north as 76.96˚ N, 71.11˚ W. In 2013, we documented successful nesting by...
