Big Game Migrations Observed Over Southeast Colorado

The migration of big game, including elk and bighorn sheep, was observed across snow-covered parts of southeastern Colorado in mid-December.

Footage shared by Colorado Parks and Wildlife’s Southeast Region (CPW SE) on December 28 shows various traveling groups of animals.

“It’s impossible to count all deer, elk, moose, pronghorn etc in Colorado,” CPW SE tweeted. “So @COParksWildlife biologists fly to get random samples. They ID herds by sex and age and use data to generate male-to-female ratios, estimate populations and compare to CPW targets.” The data gathered is used to set hunting licenses, CPW SE said.

The biologists hoped to complete their herd assessment flights by early January, according to a November 19 press release from Colorado Parks and Wildlife. Credit: CPW SE Region via Storyful
