FC01 – Day 6

30/12/2011 – Day 6
11:00
High humidity.

No physical sighting but we are glad to report that FC01 is still on the property despite having moved further towards the edge of the property.

Approx 20m from last known position.

FC01 – Day 3

27/12/2011 – Day 3
11:00

No wonder we couldn’t find it yesterday! The forest Cobra has moved to the other side of the property (and in a different direction to the one it was heading on release day).

Using our telelmetry equipment we located Forest Cobra 01 – FC01 to a region of bush to the south of our property. Trekking into the bush we located FC01 to an area where we felled a non-indigenous cactus tree, walking around the tree to see if we could get a glimpse of FC01 we were ecstatic to see a little Forest Cobra face peeking out at us from the trees above us. FC01 had managed to find an area of lower humidity with a little breeze 400m from his release site.

We were looking for FC01, but it was already watching us!

Location unknown – we searched for it at various times throughout the day. But no, it appears to have gone AWOL.

FC01 – Release – Day 1

Weather: Hot with short, light rain showers.

On release forest cobra climbed into the trees to soak up the remaining sun rays from on top of the canopy.

We thought the fallen tree was an excellent site to release FC01

Did You Know – Skink

Check out this weeks factsheet on Typical Skinks – Trachylepis (Mabuya).

-Skink  -Genus: Trachylepis   -Description: Genus of 23 species of skink that are similar in appearance, i.e. body shape. All lizards within this genus have fairly shiny scales, large eyes with movable eyelids and well developed legs. -Size: The largest species are approximately 120mm and the smallest approximately 55m in length. -Tail length: Usually the same as body length however the grass-top skink has a tail that is over twice its body length. -Behaviour: Active by day. Tend to bask in very open positions and do not run away till you get quite close to them. -Food: active foragers of insects such as beetles, grasshoppers and flies. Skinks will also bask in strategic positions that allow their food to come close to them. Some, e.g. the rainbow skink will even eat the young of smaller lizard species. -Predators: Preyed upon by many, the skink uses a method called tail autotomy to help it escape. This means that their tails shed/fall off to distract the predator from its skink prey. Many skinks have a brightly coloured tail to maximise their chances of escape, e.g. the rainbow skink and Angolan blue-tailed skink have bright blue tails. -Social structure: Skinks tend to be found in high density. This causes interaction with fighting of posturing to intimidate eachother for the best basking sites. -Habitat: Can be arboreal, terrestrial or rock dwelling. Skinks are usually able to live in a variety of habitats, however the wedge-snouted skink is restricted to sand dunes and arid scrublands. -Reproduction: Varies even among the same species- their have been recorded cases of certain populations of variable skink (pictured) giving birth to live young, but another population of the same skink will instead lay eggs. -Distribution: Widespread and common, however most species occur in the northern parts of southern Africa. -Did You Know: After shedding its tail a skink will often return and eat it.

Did You Know – Kudu

Here it is, another factsheet in our South African Wildlife collection. This week is the Kudu – join in the fun next week with the Monday Wildlife quiz on our Umkhumbi Lodge Facebook page.

 

Kudu - scientific name: Tragelaphus Strepsiceros - Description : Extremly shy of humans this South African even-toed ungulate lives in herds of up to 12. Large, with long legs they have 6 to 10 vertical white stripes. Unlike Nyala their horns are not white tipped. - Food : Browsers= Fruit, seed pods, melons - ocassionally will raid crops and is considered a nuisance in some areas. Eats young grass shoots to that have a high water content. This makes them independent of water. - Male and female : Male Kudu are greyer than the cows and calves who have a copper shen to their coats. Only male Kudu have long spiral horns. - Life expectancy : 12-15 years - it is possible to age males based on the shape of their horns. - Behaviour: Usually occur in small herds of 3-10 but have been known to form larger heards. Outside of rutting season, adult bulls are either solitary or in bachelor herds.  Usually active in early morning or late afternoon they have taken to nocturnal activity in areas where thy have been disturbed or hunted. - Habitat : Occur only in Savannah woodland, do not occur in open grassland or forest. Have been known to occur along wooded watercourses.  Prefer Acacia woodland and rocky hill country. - Reproduction : Most births take place in the summer months however calves are born thoughout the year. The Kudu cow moves away from the rest of the herd to give birth to one calf weighing about 16kg. Gestation period is is around 210 days. The calves hide for a few days until they are able to keep up with the herd. - Distribution : Occur principally in North and Eastern parts of South Africa with isolated populations in the cape province. Widely occur through central Africa south of the equatorial forests. - Did You Know? : • Kudu can easily jump over fences up to 2 metres high! • The inside of a Kudus ear is pink • The longest recorded horn length is 181.6cm - the average size is 120cm

 

Just another day… part 3

We get back late from the vets as it took the Forest Cobra over 2 hours to react to the anaesthetic.

But no sooner did we get back and install the Forest Cobra in the garage near the heater to heal, than we were off catching Nyala again.

It is about 16:30 by now and we have only a few hours of sun left, but we need to get another one! We have already dropped our target of 10 down to the more believeable target of 5 – but this already is starting to look impossible!

As we round the corner of the fence line on the quadbike we see our friendly cross-horn nyala munching away at the grass, slowing down we see a pair of curly horns emerge from the bush and stand next to cross-horn. It is one of our full grown Nyala bulls with his horns just starting to curve out once telling us his age.

Anton raises the rifle slowly – it is already loaded with the sedative dart – and carefully takes aim.

*thduff* the dart flies straight and lands in the fleshy part of the bulls rear. He turns and darts into the bush once more, we hadn’t realised that the bush there was quite as thick as it was! We quickly lost sight of him in the bush and had no choice but to wait for Johan to get the transceiver to us. It is getting dark and we have no torches but push on. But we have to find him as he could die without the reversor drug.

We were not expecting him to be able to get quite so far into the bush after the quick reaction that it had on the other bull. But we now had the transceiver and pressed on trying to find him in the dark – all fingers crossed that the transmitter was still attached to the nyala.

Eventually we find him and call in all hands to help carry him. But how to direct people to where we were? Even we did not know! Not even the moonlight was penetrating the thick bush. All we could be sure of was that we were still in the bush somewhere at Umkhumbi Lodge.

It is now 9pm and we are all exhausted after leopard crawling through the rest of the bush, under branches and between vines, avoiding the caterpillars and the buffalo thorns which will inevitably end up in various unmentionable parts of your body – all of this whilst hoping there are no snakes!

We decided that as he had been drugged for too long already the safest option was to reverse the drugs rather than risk his safety. Not to mention the fact that it was too dark to even see the Nyala never mind the way out!

We all retreat from the bush blood running down faces, arms, legs, hands and feet at the end of day 1, but we have no Nyala in the boma despite our hard work – tomorrow can only get better!

Just another day… part 2

The first snake in the second phase of our telemetry project.

Time to relocate the transmitters lovingly made by Nyalas).

So, it is 12:00 and it is time to pick up the Forest Cobra and go to the vets.

1.4 kg – similar in size to one of our first Forest Cobras – Gizmo – and yet much bigger and with more muscle mass – how?! It doesn’t make sense to us either, how does more snake = lighter.

Everything is ready, lets begin!

South African Forest Cobra safe surgery equipment

The safety gear

After popping him in the clear tube we gave the Forest Cobra the right dosage of anaesthetic and popped it back in the box to wait for it to take effect.

Nope, not asleep yet...

And waited…

and waited…

and waited some more…

When an hour had passed and it still wasn’t asleep, we added a bit more, and once more waited (we even had time to collect some hibiscus flowers and leaves to give the iguanas at the lodge a treat!).

Another 30 minutes later we looked in the box, and to our surprise…

Anaesthetised forest cobra - hluhluwe

...the forest cobra was even more awake!

We then decided to try a little gas to push the Forest Cobra into sleep.

2 hours and still awake!

But no, so we then decided to tube the Forest Cobra and try some more concentrated gas – after two hours of waiting for the Forest Cobra to sleep this finally worked, so we got started before it woke back up again.

The surgery went without a hitch and we are expecting a speedy recovery.

NB:
Two days on and the Forest Cobra is awake and even managed to eat a medium sized rat – release date is 19th December.
