A bit more PSS and some Lizards

Group photo - all the PSS entrants on Tamatieberg VolksrustTrophy winners Piet, Herman and MikeAbove and left my best group photographs. Shooting was extremely difficult in our midday sun, bright blue sky and dull brown ground conditions. Hopefully we will have our summer clouds back soon here on the highveld.

It was great to see so many beautifully finished models out for the event. Lots of effort went in to each and every one of them and such a pity we couldn't see them fly. However, I'm sure plans are already being made to get out to Volksrust and get them airborne in December.

Impressive realism - Airliner on flypastAll foam airliner performed well in the light windNot really PSS: Norbert's flying wing and the moon (focus on the moon) late Saturday afternoon - well worth the dash to the east slope when the wind picked up




















As our premier Slope Scale event is named after these reptiles, here is some interesting information on the Sungazer Lizards:

On Sunday morning we all went to Oom Louis' farm for breakfast and on the road out from the farm to the main road we were priviledged to see the Sungazers in their natural habitat. If Mike hadn't brought them to our attention, we probably wouldn't have even noticed them. These large lizards stay near their burrows and from a distance look just like sticks sticking up from the ground. On foot we managed to get about fifteen meters from them before they dashed into their burrows. I managed to get one good photo:

Sungazers are a CITES species, listed in the South African Red Data Book - Reptiles and Amphibians. Sungazers are endemic to South Africa and occur mainly in the Free State Province, with smaller populations occurring in south-west Mpumalanga and a small population in north-eastern Natal. This is the largest of the Cordylus species and can grow to a total length of 376 mm.

The Sungazer burrow
The Sungazer derives its name from its habit of anterior body-up posturing, and thus raised on its forelimbs, gives the impression that it is gazing at the sun when outside of its burrow. The Afrikaans name "Ouvolk" means old person, and has most probably been used because this lizard spends considerable sitting outside its burrow in an inactive state, either thermoregulating, or waiting for passing prey. Sungazers inhabit loamy grassland and live in, often winding, self-made burrows, which may be up to nearly 4 m in length. The orientation of most burrow openings is east through to north-west. One to two young are usually born every second year and are much brighter than the adults with bright yellow and orange markings. Agriculture and development are major threats to this species.

An environmentally conscious company such as Eskom can be commended in their efforts to protect and save this species. Around 1983, the development of Majuba Power Station in Mpumalanga, threatened the survival of a large number of Sungazer colonies. Eskom then put aside land for a Sungazer reserve and, with the help of the then Transvaal Directorate of Nature Conservation and the contractors, managed to remove over 1500 Sungazers from the power station site and very successfully relocate them to the new reserve.
