Wild News: The Lonliest Whale


In 2004, The New York Times wrote an article about the loneliest whale in the world. Scientists have been tracking her since 1992 and they discovered the problem...


She isn’t like any other baleen whale. Unlike all other whales, she doesn’t have friends. She doesn’t have a family. She doesn’t belong to any tribe, pack or gang. She doesn’t have a lover. She never had one. Her songs come in groups of two to six calls, lasting for five to six seconds each. But her voice is unlike any other baleen whale. It is unique—while the rest of her kind communicate between 12 and 25hz, she sings at 51.7hz. You see, that’s precisely the problem. No other whales can hear her. Every one of her desperate calls to communicate remains unanswered. Each cry ignored. And, with every lonely song, she becomes sadder and more frustrated, her notes going deeper in despair as the years go by.

To add to the problem, she doesn't travel the same routes that other baleen whales do, so her chances of finding a mate are near impossible.

Just imagine that massive mammal, floating alone and singing—too big to connect with any of the beings it passes, feeling paradoxically small in the vast stretches of empty, open ocean.

Wild News: Strawberry Leopard


So, there seems to be a fantastic amount of animal news everyday, and for some reason I never feel the need to share these wonderful stories. Well today, I'm changing that. This is the very first post in my new series: Wild News. I hope you all enjoy!

African leopards normally have tawny coats with black spots. But a male leopard with a strawberry-colored coat has been spotted in South Africa's Madikwe Game Reserve (map), conservationists announced this week.

A normal leopard coloration

Tourists in the reserve had occasionally seen the unusual animal. But it wasn't until recently that photographer and safari guide Deon De Villiers sent a photograph to experts at Panthera, a U.S.-based wild cat-conservation group, to ask them about the leopard's odd coloration.

Panthera President Luke Hunter suspects the pale leopard has erythrism, a little-understood genetic condition that's thought to cause either an overproduction of red pigments or an underproduction of dark pigments.

"It's really rare—I don't know of another credible example in leopards," said Hunter, whose group collaborates with National Geographic's Big Cats Initiative.

Hunter added, "it's surprising that [a photo of the leopard] didn't come out sooner, because he's relatively used to vehicles."

The Strawberry Leopard

Erythrism is very unusual in carnivores, and the condition appears most often in raccoons, Eurasian badgers, and coyotes, Hunter noted.

"There are some spotted leopard skins and melanistic specimens—black panthers—in museums with red undertones, but fading probably contributes to that," he said.

Melanism is an unusual development of black or nearly black color in an animal's skin, fur, or plumage.

The strawberry leopard seems healthy and likely suffers no ill consequences from his pinkish hue, Hunter said: "He's obviously a successful animal."

For instance, the leopard's coat still offers him some camouflage—leopards rely on their spotted fur to sneak up on prey and ambush them from as close as 13 feet (4 meters) away.

More worrisome for the strawberry leopard are the game farms that surround the Madikwe reserve, Hunter said.

If the animal were to leave the reserve, he'd lose the strict protection offered by Madikwe and become fair game for legal trophy hunting, Hunter said.

"It's the fate of a lot of leopards."
