A Wonderful Find in the Pelt Room

Snow leopardRecently I had to return several bird specimens to the Ornithology and Mammalogy department at the Academy. This project afforded me an opportunity to go into the pelt and bird room. The room, essentially a large refrigerator, was a brisk 58 degrees and packed with all sorts of wonderful specimens. Birds of all kinds stood picturesque on shelves while pelts of lions, tigers, bears among other mammals lined the walls several feet deep.

Specimens were sorted into taxonomical groups with relation to each other. Some specimens were a century old if not older, including an elephant skin shot in Africa by President Teddy Roosevelt in 1908. As mammals are my greatest love in natural history, I was in awe of the great variety of specimens. One specimen in particular took my breath away. Buried below the pelts of tigers with their massive paws was the smaller and more elusive Uncia uncia better known as the Snow Leopard. The first thing that struck me about the pelt was the length of the tail. For balance on the slippery climes of mountainous central and South Asia, snow leopards use incredibly long tails for balancing while stalking their prey of mountain goats, wild sheep, and small mammals. They will traverse up and down perilous cliffs in pursuit of prey and do so with an extraordinary balance. Watching Planet Earth recently, I was enthralled watching live footage of an actual hunt on a cliff. The speed and agility of these animals is incredible.

It was studying the Snow Leopard that made me fall in love with the big cat family and set me on a course to learn about conservation. I had to give a report in fifth grade about the cat and I still can remember drawing the body out on the board to show that the tail was usually the same length as the cat's body. I was so nervous during the talk that my lips trembled giving me a horrible stutter through out. Yet, that was the first time I became really passionate about an animal and ultimately conservation. I remember thinking "This leopard could become extinct in my lifetime…"

This is still a very likely scenario, although they are now on the "Red List" of endangered species. There are only about 7,500 Snow Leopards in the wild and fewer than 700 in zoos around the world. This animal is a perfect example of an animal's needs and habitat battling against the needs of a local people and economy. Protection of the Snow Leopard includes research and tracking. It also includes education and empowering the villagers that share a habitat with them to protect them as well. Poaching of Snow Leopards has been one of the main causes for their demise. Historically they have been hunted for their thick fur and killed as a pest because in lean years they kill the goats and sheep of local villages. Conservation groups like the Snow Leopard Trust understand that conservation is not only about research but creating economical and educational opportunities for local people who live with these animals. I am hoping conservation endeavors will continue to protect animals living in the wild. It would be a shame if in my lifetime Snow Leopards were only noted as pelts hanging in museums like the Academy.

Watching the Water

On July 16th, my Mom and I left San Francisco by boat to tour the Southeast coastal islands of Alaska. I have been hearing stories about the untamed Alaska since I was a small child. My mom lived in Kodiak as a girl. Her father and my grandfather had his last tour of Naval duty on Kodiak. His assignment was to survey the numbers of Kodiak bears for the sake of conservation. So I was more than eager to see the wildness and wildlife of Alaska.

While at sea, I've seen common Alaskan wildlife. Humpbacks have spouted and breached, raven and eagles have dived at the water for a dinner of spawning salmon. But I keep looking at the water, hoping to glimpse Orcas. The next opportunity to do so will be tomorrow coming out of the port of Victoria, British Columbia. Orcas, or killer whales as they are commonly known, are not whales at all. They are the largest species of the dolphin family and they are prominent along the Southeast islands of Alaska. They have captured the spirit of natives in these lands. They are alive in their legends and are carved into totem poles that are being preserved in the towns and museums along the coast. Both the native people here and Orcas form matriarchal societies and many native people believe that members of their tribe are reincarnated as killer whales.

Resident Orcas are just one type of Killer Whale. Three groups of Orcas have been found to be genetically separate on the nuclear and mitochondrial DNA level here. Resident Orcas stay close to the shore of the Alaskan islands in herds of up to 200. They have strongly bonded familial ties and are the fisherman of the Orcas, as their diet consists only of fish. Transient Orcas, on the other hand, live also in groups of up to 200 but will split off for the sake of the hunt. They hunt small marine mammals and migrate a great deal more, going where they can find food. While residents have a small and predictable migration route, transients are harder to research because of an unpredictable migration route. Researchers in Alaska have been able to collect more data on resident pods because of their predictability. They identify each individual by their Saddle-patch, or the white markings adjacent to the dorsal fin. It is like a fingerprint, identifying individual Orcas. The third group of Orcas is even more elusive than the transient pods. They are known as the Offshore Orcas. They are known as the rogue of the species and have been very difficult to research because of their unpredictability and often solo migration.

I am most interested in Orcas because of the question of Orca culture. They are seen as very intelligent animals by Native tribes as well as researchers. There is a controversy in the scientific field if Orcas have culture. Traits of fishing or hunting seem to be passed down to offspring denoting learning and hence culture. However, the science community is still split on learning behavior. One story I heard while here paints them as creatures of learning and remorse. One sick Orca was found in a pod. Fisherman noticed the other pod-mates line up and the sick Orca went through the line giving attention to each pod member and then left the pod after what looked like "saying his goodbyes". Was this a goodbye ritual for sending off a dying pod-mate? Whether is was or not, such unusual behavior is well worth more research. Hopefully, I will be able to see some of their behavior myself before returning to San Francisco.
