Otter On The Bow At Policemans


Recommended Posts

Guys,

 

Otters have extended their range dramatically over the past 10 years. From a boreal animal, their range now includes alpine and sub-alpine areas. . There are sightings from the Elk, Crow and north. East of Calgary is certainly possible.

Why this range expansion occurred is unknown. There has been very little research on otters. Mostly as they are tough to track. The only paper I'm aware of was produced w/o ever seeing an otter.

Like other predators, it moves with the groceries. There is some belief that trout stocking of lakes, ponds, dugouts and the like have pulled otters into new territory.

This human effect is also apparent in other birds and beasts. Ravens, whitetail deer, crows, raccoons, osprey are examples. They all have benefitted from the "human touch". Other animals have lost. This list is a lot larger.
