Big Bull Moose pursuing Cow with Calf and an Extra Arrival during the Moose Rut

Here is our Third Big Bull Moose pursuing a cow with a calf during the Moose Rut. You can hear lots of vocalizations between the Cow and Bull in this video. Most cow moose during the rut have an estrous cycle that lasts 24-25 days, however, cows may only be receptive to bulls for a brief 15-27 hour period. Here, the Big Bull smells the urine of this cow and follows with his Flehmen Response.. which is how a Bull Moose investigates the cow's readiness to mate. This Big Bull continued to pursue the Cow, but another arrival caused them all to take a step back. The arrival of another young large Bull caused a bit of a gentle dance and lots more vocalizations, but no real conflicts as He moved off shortly after seeing the larger Bull. All of these gentle Giants looked very healthy and happy, which is wonderful to witness.
