The Denali Highway is an important birding destination. It offers road access to alpine terrain - not that common in Alaska - and, in the brief birding season there, good viewing of a number of alpine breeders, including Arctic Warbler, Smith's Longspur, Long-tailed Jaeger, Whimbrel, Surfbird, Lapland Longspur, Horned Lark, Short-eared Owl, Wandering Tattler, Gyrfalcon and much more. A walk north along The Bureau of Land Management's (BLM) Maclaren Summit Trail (MP 39) can be very productive. There are also trumpeter swans and various other waterfowl in the lakes and ponds along the route.
