JACKSON, Wyo. — Fall colors mean that bull moose are on the prowl in Grand Teton National Park (GTNP).
Buckrail’s photographer Nick Sulzer spotted this large bull taking respite underneath a grove of golden aspens in GTNP on Oct. 2.
Over the past few weeks, the entire valley has been aglow with yellow, red and orange hues. The fall colors mark the abundance of berries and other foliage essential for winter preparation. During this time of year, moose eat the leaves of aspen and cottonwood trees, as well as twigs, grasses and bark, according to the National Park Service.
The changing colors also coincide with animals being more active for migration and mating. From mid-September to early October, during the peak mating season, bull moose can be found looking for cow moose near the Snake and Gros Ventre Rivers.
With the fall rut underway, moose in the region could behave more aggressively than usual. As animals move across the landscape, visitors are reminded to remain at least 25 yards away from bison, elk, bighorn sheep, deer, moose and coyotes, and at least 100 yards from bears and wolves.
