"The Scent of the Rut"

By: Christopher Johnson (Park Hill, OK)

A mature bull moose lifts his head and curls his upper lip during the autumn breeding season in Grand Teton National Park. This behavior, known as the flehmen response, helps the bull detect chemical signals associated with reproductive readiness. Framed by autumn woodland and displaying an impressive set of antlers, the bull offers a fascinating glimpse into the natural behaviors of moose during the rut.
