Coastal grey wolves in Glacier Bay National Park and Preserve in Alaska seem to be feasting well these days on an unlikely food source - sea otters. In fact, the shorelines of Glacier Bay offer wolves a cornucopia of otters and other marine menu items, providing this carnivorous predator safe and dependable locations for food and raising offspring. This week the Traveler’s Lynn Riddick speaks with park wildlife biologist Tania Lewis, whose research team is evaluation coastal wolf diets. Their goals are to identify different wolf packs and the shoreline areas important to them for feeding and reproduction. With annual visitation to Glacier Bay approaching 550,000, the team’s work will be instrumental in determining whether those areas should be protected from unnecessary human disturbance.
