Meerkats, Pups and a Puff Adder – a story from the Kalahari

Robin Hoskyns Nature Photography - Blog

 

Whilst sorting out my Kalahari photos (still an ongoing process!) I came across this sequence of images from one morning that I had half forgotten about. Looking back it was up there with the top wildlife experiences that year among the many that were had. I think it sums up a lot about Meerkats and would definitely have been worthy of a Meerkat Manor episode!

The morning started as every other morning had for 6 days a week for the last 10 months, i.e. waking up very early to arrive at the burrow of the group I was visiting before they got up and left for the day.

Luckily the burrow wasn’t too far from the farm house and I knew the Meerkats would be there because the dominant female had…

New Blog! New Website!

RHoskyns_120715_00006

I have finally completed my brand new website! There is also a brand new blog to go with it!

From now on I’ll be posting what I get up to on my new blog rather than the Kalahari blog as I’m not in the Kalahari any more. There will however be a few more posts on the kalahari blog which I haven’t got round to writing yet! If you want to receive updates from my new blog click the link below and then click “follow me” in the corner.

Hopefully I will have some lens reviews coming up and of course there will be lots of pictures!

Check out my new website here: www.robinhoskyns.co.uk

And my new blog: https://robinhoskyns.wordpress.com/

My new website has got a few new images that I’ve not shown before and a bunch of my favorites on for now but soon I’ll be uploading lots of new galleries to the archive section.

Thanks for looking!

Back from the Kalahari!

I’m finally back from the Kalahari and thanks to my parents, my return was via the kgalagadi, Namibia, Botswana and Zambia! I have actually been back for a few days but haven’t got around to getting a blog post up yet.

In the next few weeks I will be very busy trying to sort out all my images from this year, choosing some to submit to wildlife photographer of the year, working on a new, fully professional looking website, and a new blog!

My plan is to keep the Kalahari Blog going alongside my new blog for a little while as there are several posts that I have been intending to write but never got around to doing whilst in Africa.

Meanwhile here’s a picture of a Leopard from the Kgalagadi!

Meerkat Pups!

RHoskyns_130825_00047

In the past couple of months several of the groups have had pups. Meerkats can give birth at any time of the year however most mating usually occurs after the first rain of the season when males split off from their natal groups and go “roving” in search of unrelated females. Meerkat pregnancies are roughly two months long which coincides with peak invertebrate abundance after a bout of rain. The pups born in the last month were probably conceived after a couple of days light rain that we had here in July. July is in the middle of winter here in the Kalahari which is usually the dry season however as last summer was almost a complete drought the brief showers out of season have caused the first births to occur fairly early this year.

Dominant females often evict the older subordinate females in the early stages of pregnancy to reduce the risk of infanticide. The stress caused by eviction may cause any pregnant subordinates to abort which will stop any subordinate litters competing with the dominant’s.

Subordinate females do occasionally raise successful litters but usually only in good years where there is enough food to go around and the dominant already has a successful litter or when the dominant is not pregnant for some reason. In the later stages of pregnancy dominant females also become very aggressive towards subordinates and steal a lot of their food items so subordinate litters often consist of fewer pups that weigh less than a dominant’s litter.

Meerkats usually give birth overnight in a burrow and dominants usually will go foraging with the group the next day leaving behind a subordinate babysitter to look after the pups. Apart from lactating, dominant females usually contribute relatively little to pup care leaving most of the work to subordinates. Unusually for a cooperatively breeding species subordinates can also lactate for a dominants litter even if she hasn’t been pregnant

Meerkat litters are between one and five but as many as seven has been recorded. Meerkat pups will usually stay in the burrow for about two weeks before emerging above ground. They will then stay at the burrow for another week or two before going foraging with the group.

Once foraging with the group the pups will be fed prey items by members of the group, often with stings or mouth parts removed by an adult. They will then gradually learn to forage for themselves and should be fully independent by three months of age when they will be classed as a juvenile rather than a pup.

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.

RHoskyns_130322_00047

 

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.

RHoskyns_130414_00097-2

 

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.

RHoskyns_130405_00088

 

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.

RHoskyns_130716_00187 RHoskyns_130804_00001

 

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).

RHoskyns_130730_00038

 

Red-Headed Finch

Another bird only seen at my hide.

RHoskyns_130802_00049

 

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.

Game Capture

The Helicopter taking off!

The Helicopter taking off!

Back in June we had a Game capture with the aim of removing 70% of the animals on the reserve. As there was a drought this year the grass hasn’t had much time to grow so the livestock on the reserve has had to be supplemented with leucerne which is quite expensive. Capturing and selling some of the animals should bring the levels of game back to a more sustainable level.

The capture itself involves flying a helicopter around to manoeuvre the game into a large V-shaped enclosure called a boamer, with a livestock truck at one end and curtains which are pulled across to stop the game running back out of the enclosure.

All of us Meerkat volunteers got to help and it was our job to pull the curtains across. It was quite exciting staying hidden behind the curtain with a heard of Wildebeest or Gemsbok running by waiting for the siren from the helicopter to tell you to run across.

One of the guys out here with a gopro gave it to the helicopter pilot and got an awesome video which clearly shows the structure of the boamer, some of the landscape of the reserve, how the pilot herds a group of Gemsbok into the boamer with the siren and the curtains getting pulled across. You can also see that one of the Gemsbok gets separated from the group, runs back to the first set of curtains and also how close a couple of the people are to the Gemsbok. On this run I was on the last set of curtains and it was pretty hard to tell what was going on as the heard had already run past.

We got to  have a go for about 6 runs at least one of Gemsbok, a run of Red Hartebeest, one of Wildebeest, and a couple with Springbok. Most of the animals just run straight up the ramp and into the truck however the springbok try to jump the fence and get very stressed out in the truck so they have a big net which most of them get caught in and any stragglers have to be grabbed. We then had to hold them down whilst we waited for them to be injected with a sedative before carrying them into the truck. Some of the Springbok were quite lively and quite difficult to hold onto their legs whilst they were kicking!
