Fowl

A while ago, ferrebeekeeper added the new category “fowl”. So far, entries in this category include a write-up of predatory ducks, geese the size of dinosaurs, and terrifying people in duck costumes (not to mention the yet-to-be incorporated category of turkeys)—a pretty auspicious start for the topic! But what exactly does “fowl” mean? Although in English, “fowl” can be used as a general term for all birds, the word has a more specific scientific meaning: fowl denotes a combined group of two extremely important biological orders of birds, the Galliformes (game fowl) and the Anseriformes (waterfowl). Cladists, taxonomists who classify biological organisms according to shared ancestors, have discovered that birds from these two orders share numerous physiological features and descend jointly from a common ancestor (which most likely lived in the Cretaceous or earlier).
The vast majority of economically/agriculturally important domesticated birds are either galliformes or waterfowl (I am omitting pet birds like canaries, parrots, emus, pigeons, and, um, gyrefalcons, and concentrating on farm birds). Galliformes include pheasants, quail, grouse, turkeys, junglefowl, partridges, and guineafowl (among other taxa, living and extinct). Waterfowl include geese, ducks, swans, and screamers. Cladists (with typical lack of euphony) call the combined group the “Galloanserae”.
Although golden pheasants, black swans, and green peacocks seem extremely different (except in terms of extravagant beauty), the birds of Galloanserae share surprising similarities. They produce prolific clutches of eggs–which is especially unusual for large birds–and the resultant chicks are unusually precocious. Baby ducks or turkeys can soon run after their mother and baby megapodes emerge from the incubation mound ready to fly (compare that with the passerines or raptors whose young are helpless and immobile for weeks or longer).
Additionally fowl are polygynous or polygamous. Many other birds form close monogamous relationships (some of which last for life) but fowl tend to be rather, er, promiscuous. Domestic chickens are notable for their harem-style sexual relations and dabbling ducks are infamous for the violent amoral chaos of their courtship. Likewise, fowl can hybridize easily and in strange ways. Birds which live in different genera can have courtships, produce eggs, and even conceive offspring. In fact common mallard ducks (Anas platyrhynchos) originated in Siberia but have interbred so frequently with American black duck (Anas rubripes), and with Northern Pintail (Anas acuta) that the species distinctions are breaking down. Stranger and more unlikely fowl pairings are not unknown (and the resultant offspring are sometimes not infertile) but I will leave those soap opera stories for another day….
The Red Panda

Today we present the lovable red panda (Ailurus fulgens), an endangered mammal which is the only species of the only genus of the family Ailuridae. Weighing up to 15 pounds red pandas are shaped like cats—indeed their scientific name means “shining cats”—however they are not at all closely related to cats and their nearest cousins are in the superfamily Musteloidea (which includes raccoons, coatis, skunks, as well as mustelids like otters, weasels, and badgers). These kinship bonds between the red panda and the other Musteloidea are not especially close: the red panda is a living fossil and taxonomists are still arguing about where to put it.
During the Miocene era (approximately 20 million years ago to 5 million years ago), close relatives of the red panda spread around the temperate forests of earth. Remains of a very similar creature, Pristinailurus bristoli, were found in the magnificent Gray fossil site of Tennessee and fossils of other red panda like creatures have been found throughout Europe, Asia, and North America. However, today the family consists of one last surviving species which is indigenous only to the high temperate forests of the Himalayan. The animal can be found in India (in Sikkim & Assam), Tibet, Bhutan, in the northern tip of Myanmar, and in southwestern China in the high forests of Yunnan, Sichuan, and Shaanxi. Unfortunately, throughout its range the red panda is endangered from hunting and habitat loss. They are hunted for their glorious red striped coats and bushy tails which help the creatures survive the cold and blend in with lichen-covered trees (but unfortunately attract our primate eyes).
Red pandas predominantly dine on bamboo, but they are omnivores who also consume small mammals, birds, eggs, blossoms, and berries. In captivity they have been observed to eat the leaves, blossoms, and fruit of maples, beeches, and especially mulberries (perhaps this is what their extinct relatives in Europe and the New World ate). They are solitary arboreal animals who carefully guard their forest territories and seek each others’ company only during mating season.
The red panda was not well known during the twentieth century, but because it flourishes in zoos it is becoming ever more famous among new generations of zoo-goers. To reiterate, the animal flourishes in zoos even as it vanishes in the wild, so some day the red panda might be like that other magnificent orange Asian mammal, the tiger (which are now far more numerous in captivity than in the wild). Thanks to their success in wildlife centers, red pandas are growing more popular in the media world: in the 2008 film “Kung Fu Panda” an animated red panda was featured as the venerable dojo master Shifu, voiced by Dustin Hoffman (who has admitted to knowing very little about the red panda before taking on the role). Sikkim has adopted the animal as its official state animal and red pandas are also the mascots for the Darjeeling tea festival. All of this matters in a ever more human-dominated planet where a species’ charisma to people is what is likely to keep it from going extinct.
Speaking of charismatic red pandas, the world’s most famous (real) red panda is a male red panda named Babu who lives at Birmingham Nature Centre, in England. In 2005 Babu escaped into the suburban woods and, like Mia the cobra, attained media stardom before being recaptured. He was subsequently voted Brummie of the year (A Brummie apparently being a resident of Birmingham). I have often watched Red Pandas at the Bronx, Central Park, and Prospect Park Zoos and I am surprised they do not have a similar designation in New York City. No animal could be more designed to tickle human tastes or appeal more directly to the “cuteness” short circuit of our brain—at least until the red pandas smile and reveal that their jaws are filled with needle sharp teeth.
