Scorpions

Scorpions

There are quite a lot of scorpions about as they are perfectly adapted for the dry (semi) desert conditions. There are two main types of scorpion out here: the thick-tailed Paraboothids and the Cape Burrowing Scorpions. The Paraboothids are the more dangerous type.

There are four main species of Paraboothids found here and two main species of burrowing scorpion. They can all deliver a painful sting however a sting from a paraboothid is much more serious and would need immediate medical attention whereas a burrowing scorpion would merely hurt for a bit. Thankfully the two types are easy to tell apart with the paraboothids having long thick tails and small thin claws and the burrowing scorpions having small tails and large powerful claws.

All scorpions will glow under UV light and it is still unknown exactly why this happens however it does make them very easy to find at night. There are far more scorpions in the summertime as they prefer the warmer weather. Most scorpions at the moment are hiding in their oval shaped burrows or under rocks but in the summer they roam about especially on windy nights and can even be found sitting on top of bushes waiting for flying insect prey.

Scorpions appear to be the Meerkat’s favourite food item and they will dig for a good ten minutes to unearth a nice juicy one. They like them so much that injecting the scorpions and feeding them to the Meerkats is being trialed as a reliable way to give them oral doses of hormones for an experiment on the effects of anxiety on social behavior and also to administer antibiotics if necessary.

The Meerkats seem to have very high resistance to toxins from scorpions and also from snakes as quite a few have large snake bite scars from bites that would have killed a human if left untreated. However Meerkats learn at quite a young age how to handle scorpions and quickly bite off the stings before eating them.

Birds of the Kalahari – Part 2.

This is a follow up to my first bird post that had some of the birds that I see on a daily basis. This post has birds that are slightly rarer or a bit more seasonal.

See the first post here: Birds of the Kalahari – Part 1.

 

Swallow-Tailed Bee-Eater

There were a pair of these Bee-eaters that used to hang around the pool in the summer, picking off the dragonflies that were around. Hopefully they come back when it gets warmer.

Pygmy Falcon

These are the smallest birds of prey in Africa, they are probably a bit smaller than a blackbird. They use unoccupied chambers in the Sociable Weavers nests to roost in so waiting by one of the weaver’s nests will give you a good chance of seeing one.

Pearl-Spotted Owlet

Another very small bird of prey, they aren’t much bigger than the pygmy falcons. The bird books say’s that “they stare furiously at intruders” and that was definitely true of this one.

Martial Eagle

From two of the smallest birds of prey to one of the largest, these guys are huge. Martial eagles are one of the main predators of the Meerkats but can also take much larger prey. The meerkats will run and hide in a bolt hole if one flies over or stand and bark if they see one sitting in a tree. Last week someone spotted one flying over with the dominant male of one of our groups in its talons!

Acacia Pied Barbet

Very cool little bird, we had a pair nesting in a tree right next to the farmhouse. I sat with my camera and waited for them to return and was lucky to catch one poking it’s head out.

Shaft-Tailed Whydah

I have only seen one of these and luckilly it was from my hide that I have set up by one of the cattle watering holes. They are a brood parasite of the Violet-Earred Waxbill (another cool bird that I haven’t managed to get a good picture of).

Red-Headed Finch

Another bird only seen at my hide.

Bennett’s Woodpecker

There are loads of woodpeckers around as there is a lot of dead trees. I often here them pecking however getting pictures is a little more difficult. They all look very similar but this is one of the rarer ones that happens to forage more on the ground.
