Many of the blacktail deer around Mitchell cabin appear to have large sores on the inside of a back leg. If they were indeed sores, that would be worrisome. What is going on? Do their knees bump against each other when they run? As it turns out, all’s well. It’s just a matter of deer being able to do things we humans would never try.
In this photo of deer-turkey Siamese twins I posted a few weeks back, the spot on the deer’s left hind leg looks downright bloody. But as I have now read on a whitetail hunting website, what we’re seeing is not a sore but a tuft of hair whose purpose is to catch urine for the deer’s “tarsal gland”:
“Each hair is associated with an enlarged sebaceous or ‘fat’ gland that secretes an oily material that coats the hair. When a [squatting] deer ‘rub-urinates,’ allowing urine to soak the tarsal gland, the oily secretions absorb certain compounds in the urine. Studies have shown a diverse population of different species of bacteria living in the tuft of hair that makes up the tarsal gland. These bacteria interact with the compounds from urine in a way that creates the characteristic color and odor.
“Does, bucks and even fawns rub-urinate year-round, but bucks do it more often in the breeding season, which is why the stain and odor of a buck’s tarsal gland is more prominent during the rut. Changes in the composition of a buck’s urine also likely contribute. Older, more dominant bucks tend to rub-urinate more frequently, so the stained area is larger. In some cases, the stain extends down the inside of each leg.
“The exact mix of bacteria is unique from deer to deer, which may give each deer a unique scent that other deer can recognize. This scent is likely deposited in scrapes when a deer rub-urinates and urine flows over the tarsal gland onto the ground. It is likely tarsal-gland scent carries information about the dominance status, sex, health condition and possibly other characteristics of the deer it came from.”

Turning to other oddities, I’ve had two recently at the Safeway in San Anselmo’s Red Hill Shopping Center. The first occurred around the beginning of the year on a day I was driving my backup car, a 28-year-old Nissan, to give it some exercise. I parked in Safeway’s lot, but when I later tried to drive away, the battery was dead. A neighboring driver let me attach jumper cables to his battery, but it did no good. I thanked the man and went looking for a phone to call AAA.
I don’t own a cellphone, and there was no payphone to be found. Luckily a friendly woman in a real estate office let me use their phone, and I called AAA but got a dispatcher in God knows what part of the world. After I explained I needed a tow operator to get my car started, I told her it was a white, 1992 Nissan with its hood open, parked in front of the Red Hill Safeway in San Anselmo.
“Is Safeway a store?” the dispatcher wanted to know. “Yes,” I told her. “It’s a supermarket.”
“What state is San Anselmo in?” I told her “California.”
“What’s the street address….?” The dispatcher went on and on like this as the woman in the real estate office rolled her eyes. Finally the dispatcher told me a tow truck would come by in 45 minutes to an hour and a half. I groaned, thanked the woman in the real estate office, and the tow truck was there in 10 minutes. The call took almost that long.
More bizarre yet, while in the same store one day last week, I went into the men’s room and entered a stall only to have a metal panel that formed the main wall of the cubicle fall over on me. I was startled but not hurt, and I subsequently informed a store clerk that the men’s room needed attention.
The deer, at least, never have to worry about such mishaps.
