Snow geese have spectacular nesting season in Arctic; experts predict huge fall migration

Think North America already has enough snow geese?
Experts describe this summer’s nesting season in the subarctic region of La Perouse Bay in northern Manitoba as “spectacular.”
Because of a warm spring season and extremely wet conditions, nesting success was very high for snow geese, which are already at record high levels, frustrating biologists concerned about their impacts on the fragile arctic tundra.
“This is a huge production year,” says Dr. Robert “Rocky” Rockwell, a biology professor at City University of New York and one of North America’s leading authorities on snow geese. He said the number of juvenile birds migrating south would be usually high this fall.
Delta Waterfowl, a conservation group, said that should mean better hunting success for snow and Ross’ geese, a similar-looking white goose.
Overall populations of snow and Ross’ geese remain very high. One population, near Karrak Lake in Canada, has grown from 400,000 to more than a million in less than 10 years.
Snow goose survival rates have not declined since 1989, even with liberalized hunting regulations and a special spring conservation hunt.
