Réunion Kestrel

Falco duboisi

A few days ago we learned about an entire genus of Tortoises that went extinct from the Mascarene Islands in early 19th century. Today's animal didn't make it that long-- the Réunion Kestrel was gone before 1700.

It is a similar sad story, with the arrival of man prompting a fast decline... But the exact cause of the extinction is still a bit of a mystery. European colonization was in full swing by the mid 17th century, and the last time one of these birds was recorded as being alive was in 1672. A few may have hung in there for a while longer, but by 1700 they were considered extinct. Persecution probably played a part in their decline, but if there were other factors, they remain unknown.

Everything we know about the Réunion Kestrel comes from fossils and a few notes written by in the 1670s. They probably lived throughout the island, inhabiting open areas. They probably fed on smaller birds, as other Kestrels do, and may have taken domestic chickens (prompting some of that persecution). Unfortunately, little else is known about their behavior and lifestyle, as they were only known to science for a few short years before completely disappearing.

Réunion Kestrels are the only Kestrels to have gone extinct. Interestingly, the nearby island of Mauritius has its own extant Kestrel species, though it is listed as Vulnerable.

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!

Animal A Day!
