Western Jackdaw

Corvus monedula
Meet the Western Jackdaw. These mostly-black birds are the second smallest members of their genus, and are one of the littlest species in the entire Corvid family. Western Jackdaws can be found across Europe, as well as in North Africa and Central Asia. Most of the populations are residents, though some in the north and east migrate. They are a very adaptable species, and can be found in habitats that range from sea cliffs, to meadows, to urban building ledges!

There are actually four different subspecies of Western Jackdaw. All of them differ by location and by their head and neck coloration. All four have dark grey/black bodies, but the size and lightness of the crown varies.

Western Jackdaws
Western Jackdaws are incredibly social, and can be found in large flocks that number into the hundreds. These flocks function with a strict hierarchy, and birds will fight and create threat displays to assert dominance. The birds are also very social when it comes to feeding. Not only do the flocks forage together, but they also share their food with one another. They are opportunistic with their feeding, taking grains, insects, eggs, and just about anything else they can find.

During the breeding season the birds pair up, and most of these couples will stay together throughout their lifetimes. Pairs will preen and groom each other to strengthen their bond. They build nests in crevasses, dropping sticks in order to make a platform (which can be problematic for chimneys). They lay 4-6 greenish-blue eggs at a time, and both parents incubate, defend, and care for their offspring.

Western Jackdaws are under no real conservation threat whatsoever. In fact, it is estimated that their global population is somewhere around 90,000,000 birds and rising. They are able to be hunted in several different countries throughout their range.

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

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!

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.
