During the elk’s mating season in late September and early October bull elks put on an animalistic symphony. This raucous courting ritual which can include sounds from deep guttural bellows to high-pitch grunts is called bugling and there is no better place to hear it than in the eastern parts of Rocky Mountain National Park (near Estes Park, Colorado). With thousands of elks in the park during the summer season catching the animals in the act of bugling is easily doable especially around dusk or dawn which are prime viewing-slash-listening times.
Watching the rut has become so popular in Rocky Mountain National Park that in 1990 the Elk Bugle Corps was enacted. This group of nearly 100 volunteers helps educate, guide and oversee the hordes of visitors that campout on the side of Trail Ridge Road near Horseshoe Park, Moraine Park and Upper Beaver Meadows every fall to hear nature’s call.
