Feral February Episode 12 – The art of the aardwolf

Throughout the month of February, which I am calling “Feral February,” I am going to do something a little bit different – I’m going to create a series of theme posts every week day about my favourite things in the world: Animals.

Today’s animal is the aardwolf.

Unlike its name suggests, the African aardwolf is not related to the aardvark (although it does eat termites with its long and sticky tongue), but is actually closely related to the hyena.

Resembling a small hyena, the aardwolf has three vertical stripes running down each side of its body, with diagonal stripes along its neck and legs. Like other hyenas, its longer front legs than back, pointed ears and a distinctive mane that goes from its neck to shoulders than can stand up if the animal needs to appear larger.

Originally thought as solitary animals, aardwolves are socially monogamous, meaning they form mating pairs and help raise to young until they can fend for themselves and leave the territory. However, a dominant males may also mate with other females within neighboring territories. Unlike most termite-feeding mammals like the anteater and aardvark, the aardwolf does not dig into a termite nest, as it lacks claws. Therefore, the aardwolf licks them up from the ground and may eat over 200,000 termites in one night.

Daily dose of trivia:

Aardwolves have areas within their territories for urination and defecation called middens. Individuals dig a hole in the midden each time they visit, and once they do their business, they pile dirt on top and cover it up

Feral February Episode 7 – Keeping one jump ahead

Throughout the month of February, which I am calling “Feral February,” I am going to do something a little bit different – I’m going to create a series of theme posts every week day about my favourite things in the world: Animals.

Today’s animal is Merriam’s kangaroo rat!

Rats and other rodents get a bit of a bad rap, especially the ones found around the house. But those are only one or two species of rats, and there are many more rodents found around the world – including the beaver, hamster, and lemming.

Merriam’s kangaroo rat, named after famed American zoologist and naturalist Clinton Hart Merriam, is only a few inches in length, with a long tufted tail that can easily be as long, if not longer, than the length of the body. It also possesses large back legs and feet, like the kangaroo that it was partially named after, that propel it across the sand of the southwestern United States at great speed. But unlike other rodents, which run, Merriam kangaroo rats hop and jump, just like a kangaroo, and use their tail for balance.

Most kangaroo rats, and Merriam’s is no exception, are nocturnal. Because of their small size, they tend to avoid the heat of the day and hunt for seeds in darkness.

Within their cheeks, they have pouches used to store food while they are out gathering, returning to their burrow every so often to eat a little and save the rest for later.

These animals also maintain extremely complex burrows systems, with multiple entrances/exits, so that protection from predators is never too far away while out gathering food. These burrows are also well-organized, with separate chambers for babies, sleeping, and food storage.

Daily dose of trivia:

Merriam’s kangaroo rats can jump as far as six feet, and thanks to their tails, can even change direction in mid-air, as the tail acts as a rudder to help steer the animal.
