Mountain Bluebird

Sialia currucoides (male)
Spring has arrived (for now), and the songbirds have returned to my neck of the woods. Now, to be fair, today's bird doesn't live anywhere near me, but I'm sure they are fluttering around by some of my western readers. Allow me to introduce you to the Mountain Bluebird, the state bird of both Idaho and Nevada.

Mountain Bluebirds come in different colors, depending on the sex of the bird. Females are a dull brownish-grey, with hints of light blue on the wings and tail. Males, on the other hand, are a very bright blue all around, with the underparts lighter than the top. They use their colors, their calls, and their carefully scouted nest locations, to attract mates.

When it comes to nesting habits, most of what we know comes from the birds that raise their young in man-made nest boxes. Females do almost all of the actual nest building, as the males for some reason tend to drop the materials en route to the site (and that's if they even help at all!). Thankfully, the males make up for their lack of building expertise by being great food providers. They deliver meals to the mother and their chicks. Mountain Bluebirds feed on insects, hovering in the air or waiting on a perch before swooping down for a catch.

The species has a very large range, and thanks to all the man-made nest boxes, the birds are doing quite well for themselves. Once upon a time their numbers were decreasing due to the nest site competition caused by habitat loss, but now the population is stable and the bird are listed as being of Least Concern.

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
