Swan Goose

Anser cygnoides
The Swan Goose is a very large Goose that breeds in China, Russia, and Mongolia, with some small populations also being found in surrounding countries. They breed in wetland areas of the steppe and taiga, and during the winter they migrate to more coastal areas. Though they are waterfowl, these Geese aren't often found in the water-- they graze on dry land. They feed on sedges and berries, typically at night, with their diet shifting each season to accommodate what is available.

Swan Geese are the ancestors of two different Domesticated species-- the Chinese Goose and the African Goose. Most other Geese trace their lines back to the Greylag Goose which is native to most of Europe and Asia. Swan Geese are the second largest Geese in their genus, just behind the Greylag.

Unfortunately, Swan Geese are listed as Vulnerable. Though their domestic descendants can be found around the world, they themselves are threatened by unsustainable hunting and habitat loss. It is estimated that there around around 90,000 left, though the population is on a fast decline.

Their wetland breeding areas are being  used for development and agriculture, so the birds are being forced into very small ranges. The major downside to these small breeding ranges is that a single localized natural disaster can completely wipe out a huge portion of the population. The birds are protected in several areas of Russia, Mongolia, and Korea, but there is much more to be done to keep these Geese from going extinct.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a


For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!


The Binturong ( Arctictis binturong ) also has an equally awesome alternate common name, the Bearcat! However, it really isn't much of a bear OR a cat. While it is true that it is part of the Feliforma suborder, it is not a member of family Felidae. Binturongs are a part of their own family, Viverridae, which is shared with Civets, Linsangs, and Genets. There are six subspecies of Binturong, all of which have slight differences based upon location and habitat. Binturongs range in body size from 60-100cm in length, (not including their tail which has roughly the same length) and weigh between 20 and 30lbs. Binturongs are nocturnal animals native to the rain forests of South East Asia. The species range spans through several countries including China, Malaysia, Indonesia and the Philippines. They are tree dwelling mammals, and have fully prehensile tails that basically double their body length and can be used to cling to the trees or to grasp food. Binturongs are phe
