In one severe blizzard, populations of these birds might be reduced by 50 percent or more. Mild weather in late fall tends to retard the migration and tends to concentrate ducks and geese, which makes them vulnerable to diseases, such as avian cholera. While a short migration might seem safer, Berg said migrating species are designed to disperse southward and probably are healthier because of it. Berg said that deer are having a party. Food is easily reached and natural enemies, such as coyotes and wolves, don't have the advantage that snow provides.
Nothing bothers a sleeping bear much.
And they don't come out any earlier either. Carrol Henderson, DNR non-game supervisor, said what's good for hawks and owls this winter has been bad for field mice. Ditto for songbirds. Minnesota's timberwolves might not be howling with joy. I suspect small mammals are playing a larger part in a wolf's diet right now.
