Cobb's Wren

Troglodytes cobbi
The Cobb's Wren is a small, mousy brown bird endemic to the Falkland Islands. They tend to live near shorelines and feed on the invertebrates that live among the beach grasses and kelp. Their coloration and ground-dwelling nature makes them hard to spot, but they love to sing. You will most likely hear them before you see them.

Cobb's Wrens are one of the many, many species of island bird that is suffering from the introduction of non-native species. These little Wrens adapted to lives nesting in long, dense tussac grasses and ground crevasses. This allowed them, and their eggs, to remain safe from the avian predators that they share their home with.

...But then the people showed up on the Falkland Islands and they brought rats and cats with them on the ships. These new predators were easily able to hunt down the docile birds and their ground-laid eggs.

Cobb's Wrens are now completely extinct on the two largest islands in the Falkland chain, and are restricted to a couple of small, rat and cat free islands. Rat eradication has been ongoing for the past decade, with success on several of the islands. Population surveys are also ongoing, and their are hopes that the rat removal will encourage the Wrens to recolonize.

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!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
