Two yearling moose relocated out of Twin Falls Park

Two yearling bull moose were captured out of Idaho Power's Twin Falls Park and relocated to more suitable moose habitat.

On Wednesday, May 21, Magic Valley Region wildlife staff successfully darted and relocated two yearling bull moose from Idaho Power's Twin Falls Park to suitable moose habitat in the southern portion of the region. The moose were first reported on the evening of May 20, but with park gates closed for the night, relocation efforts were postponed until daylight.

While seeing moose can be an exciting and memorable experience, the presence of large wildlife in areas with high public activity raises safety concerns—for both people and the animals. Each spring, Idaho Fish and Game receives reports of moose moving through neighborhoods, roadways, and nearby schools throughout the Magic Valley. 

These reports typically involve yearling moose that have been recently driven away from the cow moose as she prepares to give birth to this year's calf. 

"Our goal is to allow wildlife to move out of populated areas on their own," said Mike McDonald, Magic Valley Regional Wildlife Manager. "But when wildlife lingers in areas with high public activity, especially near homes or parks, we sometimes have to intervene for public safety and the well-being of the animal."

The decision to use anesthetic drugs and relocate wildlife is not made lightly. Immobilization involves the use of potent drugs and carries inherent risks for both the animals and Fish and Game staff involved. However, when moose do not leave on their own, relocation becomes necessary.

Moose are common species here in southern Idaho, and while they may appear slow and awkward, they are surprisingly fast and powerful animals. They can become aggressive if they feel threatened, particularly towards people and dogs. 

Idaho Fish and Game encourages residents and recreationists to keep the following safety tips in mind when living or spending time in moose habitat.

  • Make noise if a moose is nearby to avoid surprising it.
  • Keep dogs on leash. Moose can view dogs as a threat, never allow your dog to chase a moose.
  • If you encounter a moose, observe behavior for signs of stress and agitation, such as pinned-back ears, raised neck hair, snorting, grunting, or hoof stomping. If you notice these behaviors, put a barrier between yourself and the moose—such as a vehicle or tree. 

Moose may be more likely to charge during certain times, including:

  • When a person or dog comes between a cow and her calf.
  • During the mating season, when bull moose are more aggressive and unpredictable.
