American Dipper

Cinclus mexicanus
I confess, when I hear the term "Songbird," I usually think of a bird that lives up in the trees, flitting around eating seeds or insects. But today I learned that there are Songbirds that actually submerge into water for their food! Meet the American Dipper, the only truly aquatic Songbird in North America!

You'll find these birds around fast moving, rocky rivers. Their range runs down the western side of North America, from Alaska all the way down to Mexico. American Dippers are residents, and when it gets cold they move to larger rivers that do not freeze. The also adapt to the cold by having a thick coat of feathers and a low metabolism.

Did you know that American Dippers molt all their wing and tail feathers at once (a simultaneous molt) and cannot fly for a short period of time? Though many waterfowl species do this, most songbirds do not, making the Dippers even more unique (Songbirds molt, but it is a more gradual process).

American Dippers feed on underwater insects and larvae. They have membranes over their eyes that let them see well underwater, and have oily feathers that keep them insulated in the cold streams. When searching for food they will dip their entire body underwater over and over. That dipping motion is what gives them their name. They will also search for prey by walking on the river bottom!

    All birds molt.

      Yes, they do. I had that paragraph worded really badly. Thanks for the catch!

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...

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills. IUCN Status :  Not Listed ...

Four!

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!
