ESP 190 Spring 2013 Tuolumne River Trip Species List

Sarah Carroll

As a wild biologist, every time I travel to a new habitat, or go on a small adventure, I think about what interesting animals I might find living there.  At the end of every outing, I generally make a list of all the species I see or at least hear in my head. Eventually this list, (which I must admit is more often than not biased towards vertebrates) will make it into my journal for antiquity. During our time on the Tuolumne this June, we saw some rare and spectacular animals that I for one, am stoked to add to my lifetime list. I’m not sure that anything can top our sighting of the Bald Eagle, complete with a nest and rearing juvenile. This was my first time seeing a Bald Eagle and in the setting of the epic and gorgeous Tuolumne River, in awe of its beauty, I will never forget it.
