Beavers Especially Vulnerable
Little did I know when I wrote yesterday’s post about the silver lining of our low water levels that I would so quickly encounter another predator benefiting from the current drought. I have spent a considerable amount of time this summer watching three generations of beavers do their best to survive as their pond proceeded to diminish to the point of exposing one of their lodge entrances and confining them to an increasingly small body of water. The underwater entrances to a beaver lodge are vital to their protection, and predators are well aware of this.
Yesterday the importance of water as a protective barrier was made very clear to me when a coyote appeared on the opposite shore of the beaver pond from where I sat. It stood for several seconds exactly where the beavers leave the pond on their way to nearby woods to cut poplars and birches which they haul back to their pond to eat. A well-worn trail marks the spot. You could imagine the coyote, upon surveying the shallowness of the pond, telling itself to be patient, as better days were just around the corner.
Moments after the coyote left, the mother beaver got out of the pond precisely where the coyote had been standing and took a few steps before sniffing the ground and then the air (see insert). Being nocturnal, beavers have an acute sense of smell which they use for detecting danger, food and for communication with each other. It took mere seconds for the beaver to detect the scent of the coyote, at which point she turned and sought refuge in the dwindling amount of water remaining around her lodge. May the heavens open up soon.
