Tundra Swan

The Tundra Swan is the more widespread and northerly ranging of the two native swan species in North America. In Arctic Alaska, they nest in wet to dry tundra habitat types preferring islands in lakes or ponds, or naturally occurring frost heaves at the intersection of polygon pond rims. Nesting territories almost always include a large lake that the family will use as a safe haven from terrestrial predators (Limpert and Earnst 1994). During the breeding season, their diet is primarily vegetarian, eating emergent and submerged vegetation in lakes and ponds. They also graze on terrestrial vegetation near the water (Limpert and Earnst 1994). Most North Slope breeders winter on the east coast Mid-Atlantic States (Limpert and Earnst 1994). The current Arctic Coastal Plain population is estimated at approximately 10,000 (Larned et al. 2012).
