Rudolph Versus Bambi: A Conservation Story

Big Fish: Rodent-Eating Trout

As an avid fly fisher, I had heard the stories.

By day, the trout of Silver Creek—a clear, spring-fed stream in southern Idaho—fed on tiny mayflies and caddis flies. The water dimpled as trout sipped the profuse insect life from the surface. People like me used equally tiny artificial flies to try to  mimic said insects, often an exercise in extreme frustration.

By night, though, river monsters ruled: giant brown trout cruised the depths, occasionally surfacing to gulp down any hapless rodents that fell into the stream.

There’s something appealing, at least to an angler, about a trout that attacks mammals. Maybe it’s the thought of our favorite water transforming into a scene from Jaws.

Maybe it’s an antidote to the frustrations of tying delicate flies that practically require a microscope:  If I came back at night, I could just chuck a giant hairball!

But these mice-gulping trout always carried a strong whiff of, well, the classic fishing story. High on drama. Short on fact.

Silver Creek, after all, is one of the most-studied trout streams in the world. And there were no confirmed reports of trout dining on rodents.

Silver Creek also has one of the highest densities of aquatic invertebrates anywhere. The trout surely had easier prey than the occasional mouse.

Then biologists examined some brown trout stomachs.

What they found wasn’t pretty.

But it sure did validate some heretofore questionable fishing stories.

Notes from Silver Creek: Natural Born Scientists

It was a normal Sunday for us.  Mid-morning, we walked down to the creek to throw some rocks in the water and look for critters.

My boys were standing on the bridge, throwing stones, and I walked down the road to get them a few more rocks.  My five year old, Ben, said to me, “Mom, don’t go over there.”

I asked why and he said, “Because there is a bird asleep in that tree.”

I looked up and sure enough, a nighthawk was sound asleep on one of the horizontal branches.  I asked Ben how he knew it was there and he looked at me like I was not the smartest person in the world and said, “Because there’s a bunch of bird poop on the ground there.”

Watching my boys grow up on The Nature Conservancy’s Silver Creek Preserve in south-central Idaho–where I work as manager–I am amazed on a daily basis how much they notice. 

They know exactly where to find big spiders (“where there are lots of bugs, Mom”), the big black beetles (walking across the dry spots along the road, of course), the ladybugs (on that pokey green plant) and the frogs (where the banks hang over the water).

They have learned habitats simply by looking for the bugs and critters that live there.  Long before formal training, they have keen observational skills and know what questions to ask.

They are, in essence, highly effective little scientists.
