The bull elk performing the flehmen response. By curling his lip, he can detect whether a cow is in estrus. With each female only in estrus for a brief time, it’s important for the bull to seize his opportunity to mate! #rut #elkrut #elk #bullelk #foryoupagereels #fyp #wildlifephotographer #wildlife #wildlifephotography #colorado #estespark #rmnp #reelsfbシ #animallover | Colorado Wild Photography

The estrus buzz is heard when cows are fired up in a herd on a fence moving from fields or generally on the move. It adds a lot of realism! I personally love it! The call I am using it the @huntriven RS1 ! #huntriven #elkcalling #elk #wapitiwednesday | Beau Brooks | Facebook
