Siberian Weasel

Mustela sibirica
Meet the Siberian Weasel, also known as the Kolonok! These Mustelids have a huge range that spans across not just Siberia, but China, Mongolia, India, and several other east and central Asian countries as well. They have also been introduced to parts of Japan.

These long, slender mammals have impressively long tails-- they can be half their entire body length! They have fur that ranges from blonde to red, and have black masks and a white snout.

Siberian Weasels live in burrows, but the term "burrow" is very non-specific. They will hang out in tree stumps, fallen logs, and in dens that were built by other mammals but were vacated. The Weasels tend to have multiple burrowing sites-- one primary location and a number of more temporary hiding places.

Theses burrows are also were the Weasels care for their young. They line the area with feathers and other soft materials. Mating takes place in April and May, with a gestation period of about a month. A female can give birth to 10 offspring at a time, and the young ones are born blind and helpless. They grow very quickly though! By August they are off on their own!

Siberian Weasels, like many of their breathern, have pelts that are used by humans. In this case they are very popular with paint brush manufacturers. They don't do well in captivity though  so the hairs are usually only taken from wild individuals, making the brushes more expensive. At this time the range of the Siberian Weasel is quite large, and they are numerous in number, so human hunting has not massively affected their population.

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

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS


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!
