Reunion Harrier

Circus maillardi
Like many of the birds found on Reunion Island in the Indian Ocean, the Reunion Harrier is a threatened species. Listed as engandered by the IUCN, this bird of prey is found only on that one island, and only around 500 birds remain. They are the only raptor that breeds on the island.

Reunion Harrier are members of the family Accipitridae, which contains the Hawks and Eagles of the world. Males are dark, almost black in coloration, with lighter underparts. Females are actually larger than the males, and are more brown in color.

During the breeding season, males perform aerial displays and make a series of calls in order to attract a mate. Once a partner has been found, a nest is built in tall, forested areas.

Reunion Harriers once lived off birds and insects, but the human introduction of rats and other rodents has caused those to be added to their diet as well.

Reunion Harriers are protected on their native island, but poaching and loss of breeding grounds have continued to pose threats.

Location : Reunion Island

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!

10 Years?!
