I have a not very secret fear of bears visiting me at night when I am camping. But as we crawled up the Sierra foothills behind a sluggish RV on the way to Berkeley Tuolumne Camp I could see a silver lining: we'd get to add black bear to the list of California mammals we've seen.
At camp I sat on the shady deck of our cabin, enjoying the rush of the South Fork of the Tuolumne, and browsed through Mammals of California and A nature guide to Berkeley Tuolumne Camp looking for mammals we might spot. The latter was UCSC alum Phil Coffin's senior project. We should be so lucky to find such a guide to all the places we go a-mammal-hunting.
With its help we saw the pallid bat and the California myotis. You see, the Mammals of California book has a handy dichotomous key with which it is simple and pleasant to identify a bat. Why, first you simply determine whether your bat has one or two pairs of upper incisors. And then you check whether it has a furred or nude interfemoral membrane. I don't know about you, but little old rabiesophobic me is not about to check out the number of incisors a bat has even if I could catch one, which actually was pretty likely as one night they were flying all around our heads in clouds.
Woman playing pingpong with cloud of bats around her head: "Did someone say bats? Are there bats around here?" Looks up, screams, clutches head.
Here is my best photo. Can you make out the incisors?
I'll need to fiddle with my camera or maybe even take a class to improve my night photography. I was trying to shoot on automatic settings and it wouldn't flash because nothing was in focus. Darned bats move too fast to focus on. However, you know what doesn't move fast? Bat guano!
Under the Hardin Road bridge, as promised in our guide. How exciting! There it is again, that way that a project changes your outlook. As part of a project bat guano=exciting! After finding the guano we settled down to wait for nightfall. Well, I settled down. The kids swung on the rope swing.
The Mammals of California book also suggested we attach cyalume capsules to sleeping bats we might find in caves which would allow us to track their movements after dark. I wish I could say I had done this. With gloves on. And a respirator. Because I do not want to get rabies just because I think it would be a real knee-slapper to watch a bat fly with a glowstick glued to its fur.
But the beloved and practical Nature Guide to Berkeley Tuolumne Camp told us that pallid bats roost under the Hardin street bridge and fly out in the evening to catch insects.
We waited, they flew out. Check. The California Myotis, it told us, scoops water from the river. Stroll out, it says, and watch them after dinner. Done.
The best tip was this: a ringtail lives in the dining hall and comes out in the evening. If you are like many people at camp you are saying a ringtail what? A ringtail lemur? No, no. They were once called Ring-tailed cats, but the same folks who took the fish out of starfish took away their cat. These raccoon cousins are now known simply as ringtails. Gold miners loved ringtails we are told, because they eat vermin.
Since ringtails are, according to Wikipedia, "nocturnal, solitary, timid, and rarely seen" we expected it to be a challenge to see one. But the Nature Guide told us, "Some nights in the D-Hall, you may see a shape dart across one of the rafters, and it may even stop and stare at you with huge, curious eyes." So we began, with great anticipation, to stake out the dining hall in the evenings.
Ok, so this is how we staked out the dining hall. We would pass through it several times in the evening and look up hopefully. No luck. One morning as I made my coffee with my Clever Coffee Dripper (thanks, Moira!) I overheard people talking about having seen the ringtail the night before. We realized that we weren't going to catch something that darts along the rafters by passing through from time to time. We'd have to have a real stakeout.
We entered the dining hall at 9pm. Here is Evelyn staring up at the rafters.
I cheered myself up a little bit with the memory of the bats and the bear scat and the ground squirrel. And then I looked up. To see a ringtail staring down with huge, curious eyes.
We all backed up. But to our surprise it struck out straight across the floor. It paused at Evelyn's foot and looked up at her. I thought it might run up her leg. Then it scampered beneath the tables and benches and squeezed into a bench seat at the far side.
Clem made the owl that perches in the pic below on the railing above our cabin number.
Greta was seldom without face paint.
I hoped the owl would scare away the squirrels.
It didn't. They must have heard me vowing to spend less time on the computer when we got back to civilization and decided to help. Because when I was packing up look what I found.
Coming soon: We have a trail camera. We plan to set it up in the backyard and see what's there when we are not.
