Trachylepis striata (Peters, 1844)

I know that World Sparrow Day is supposed to be about Synanthropic (read - urbanisation-tolerant) birds, but I'm just trying to be a bit topical, which is why I'm going to throw in this:

Photographed in Chongwe, Lusaka, Zambia in August 2011, using Olympus E-420 with Zuiko 40-150mm lens and 2 KOOD magnifiers.

Over most of Lusaka, and a hefty portion of central and southern Africa, this is the outdoor lizard of urban habitats, which makes it a little surprising that my dictionary of Chewa and Nyanja has no word for 'Skink', beyond the generic lizard 'Buluzi'. Unlike the formerly successful bleuskops and goggomanikes (tree and ground agamas, respectively, but my spelling is probably wrong) these lizards are quick enough to flee, and to breed, that their populations can survive that nemesis of urban biodiversity, the domestic cat (please, people, keep them under control. Would you let a dog or a hamster wander into other people's gardens and across roads? No, no you would not. So why would you let your cat terrorise everything?).

And yes, that sentence is rather tangled. Parentheses have ruined my fluidity.

Anyhow, this little chappie is:

Trachylepis striata wahlbergi

(Peters, 1869)

And, despite being capable of delivering a sharp pinch with is blunt-toothed jaw, it is harmless. It's also fond of eating just about everything smaller than it, be they houseflies, crickets, ants, spiders, or even small frogs and lizards. This one is part of a population around a dried-out reservoir that co-habits with and occasionally snacks upon the much smaller Trachylepis varia (link is to post from Aug 13). They are generally seen vanishing into cracks in walls within areas where catapults are a common toy (I'll refrain from ranting, but just DON'T give small children projectile weapons. It shows a complete lack of foresight and environmental conscience, among other things), and watching lazily from walls where catapults are rare. They don't cope all that well with plastic buckets being left upright and unchecked close to walls, or smooth-sided cardboard, so be considerate, and check these regularly to avoid finding lizards dehydrated to death. 

To encourage them: ensure that there are raised surfaces, such as logs, rocks or walls, close to extensive hiding places. Most urban gardens provide this anyway. Discourage cats, and do not use pesticides. These little fellows - along with the aforementioned agamas - are actually very good at keeping most pest insects below damaging levels, provided they're not being poisoned. 

Here's a more complete (with the exception of the damaged tail) photograph of Lusaka's most abundant skink:
