I'm teaching ecological restoration at the University of Pennsylvania this term as an Adjunct Professor. It's a class for graduate students, and I have taught it every other fall term since 1992 - that's 22 years now, about as long as some of my youngest students have been alive.
I'd like to take the students on a lot of field trips. The more that they can get out in the field to see actual restoration work, the better. But UPenn is very near the heart of Philadelphia and it's hard to get to a site, take a tour, and get back to campus in the allotted 3-hour class period. So, I always offer a weekend field trip to my preserve. We did the trip this last weekend.
Many of the students are foreign nationals, and most don't own cars, so they use the regional rail network to get near my preserve, and then Kali and I pick them up at the train station. Yesterday's trip started off badly - a 60-year-old man walking on the railroad tracks was struck and killed by a train (it happens more often than you might imagine; most victims are suicides), which delayed the start of the trip by one hour. But the students all finally arrived and we enjoyed two hours of nearly perfect early autumn weather.

Two years ago, a birder found a Sora on another of our grassland trails, but that bird was dead.
I have no idea why a fairly uncommon bird almost always associated with marshes would be found high and dry in the prairie-like grasslands we have established on parts of our preserve. Nor do I have any idea why these birds are in bad shape. It's great that they're here, but not if our preserve is acting as a "sink" in which the birds fall victim to predators or disease.

|The Gimp Twins, Kali (left) and Doppler. Doppler's left forepaw is bandaged.|
On Thursday, we had to euthanize our 17(?)-year-old cat, Doppler. I added the (?) because we don't know exactly how old she was because we brought her indoors 17 years ago; she may have been older. Doppler got her name because she looked exactly like her mother (or her sibling?) - another stray cat that used to hang around outside the house with Doppler but who disappeared one day; Doppler stuck around, and "Doppelganger" got shortened to Doppler.
Doppler entered our lives with a bandaged leg, and she exited the same way. We originally had to bring her indoors because she'd gotten into a fight with an animal outside, which left her with a badly injured leg. Because the animal with which Doppler had had a tussle could have been rabid, our vet gave us two choices: (1) euthanize the cat or (2) bring her inside and isolate her for four months to make sure she wasn't rabid. Obviously, we chose the second option, so the vet bandaged Doppler's leg and we took her home. She lived in the basement for those four months; it must have felt like a prison to a cat that had been used to living outdoors. We gradually became acquainted and she was fully domesticated at the end of her confinement.
Doppler generally was a good cat, but she definitely was "queen" of the household. We've had two other cats during the time Doppler lived with us, and she just barely tolerated them. The other cats quickly learned their places in the pecking order.
Doppler loved Kali more than she did me, even though I fed her, cleaned her litter box, and groomed her. She looked forward to "lap time" with Kali every evening, and she let us know if we were late going into the living room to watch television for an hour before bed.
Doppler began to decline about two years ago. She developed thyroid problems and had to be medicated twice a day. She also developed gingivitis and some tooth loss, but she was getting too old to sedate for a tooth cleaning. Then, three weeks ago, she started hobbling around the house, clearly in pain if she put her left forepaw on the floor. One of the vets in the practice we patronize couldn't definitively diagnose the problem and gave Doppler pain medication, but the problem worsened. A second vet diagnosed the problem as either a tumor or an infection in a toe. He bandaged the leg because her foot was bleeding profusely and put her on a course of antibiotics. After a week, it was clear that the antibiotics didn't help, so the vet recommended amputating the toe; he said there were really no other options. So, we scheduled the (risky) surgery for Thursday morning. However, when I went to get Doppler to take her for the operation, I found her crying pitifully, back legs splayed out and useless. When I tried to move her, she cried out in anguish.
I called the veterinary practice, cancelled the surgery, and begged for an immediate appointment. They saw us an hour later and said that most likely a blood clot had lodged in the arteries serving Doppler's hind legs. There was nothing they could do for her, and we decided to euthanize her. I'll admit I blubbered uncontrollably. I buried her that evening alongside the other cats with whom we've had the privilege of sharing our lives.
Oh...about the image of the Gimp Twins. Three weeks ago, Kali slipped and fell down three steps. She twisted her ankle and broke a bone in her right foot. She's been in a "boot" and on crutches ever since, and has limited mobility. She goes back to the doctor on September 16 - not a day too soon for either of us!
