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.

Moose Rut Season

The Active Moose Rut Season Time and Duration

The active peak of rutting season for moose is the first two weeks of October. Farther North in the hemisphere is earlier as South is a bit later.

Early in September, however, even though no mating occurs, moose cows behavior changes towards bulls that begins to allow courtship. Bull moose come down from altitudes into the valleys and cows will socialize with bulls for the purpose of reproduction. Moose may be witnessed in small groups at this stage. Fights among bulls at this time may be possible as they begin to compete for the right to court cows.

During this early rutting phase, bulls and cows can be heard vocalizing sounds that are not usually heard at other times of the year. Moose Bulls are normally quiet, but as the rutting season starts, bull moose will announce their presence with a low-frequency grunting or gulping sounds that many call a croak.

Beginning of the Moose Rut

In the first two weeks of October, bulls will court cows for mating purposes. The largest and heaviest of the Deer family may still be seen in groups during this time, with both Bulls and Cows potentially competing for mates. Moose Bulls will chase off or even fight rivals for mating rights, while cows that occupy the same area may also chase each other away from a favourite bull moose.

While cow moose are in estrous the bulls will stay in the area, mating several times to ensure successful breeding happens.
