Southern Tree Agama, Blue Headed Lizard, Bloukop Koggelmander, Acanthocercus Atricollis
Head bobbing regular visitors in the garden is the Blue Headed Lizard, bigger than skinks running around in broad daylight enjoying the sun, the Bloukop is not poisonous and may become relaxed in a Durban garden when realizing no threat or danger is apparent.
Possessing extremely good sight they will run for the first tree to avoid dangerous encounters, they pick up good speed when on the run.... Should you ever catch one be warned, although they have no venom the could give you a nasty bite defending themselves.
Due to urban population increasing these lizards are not seen regularly, killed by vehicles, habitat destruction, domestic animals everywhere, along with some humans fearing them thus killing them for no good reason! Some humans keep them as pets making trade in lizards another concerning factor, our high population of monkeys stealing eggs laid is most definitely another problem.
What is interesting is this lizard does eat ants and millipedes making it unique in the lizard world, with sticky mucous glands on the tip of it's tongue, makes for excellent tool for collecting ants, they also tend to leap into the air occasionally for moths, beetles and flies.
Males (like males in most species) will fight for domination over females and territory, these lizards normal do more posturing and sizing each other up before conflict, however conflict does happen, as Carol managed to capture in her backgarden here in Durban. Battle of Rival Tree Agamas
Females blend more into nature, camouflaged similar to the males, without the flashing blue colour to attract females during mating season August to October, he may attract more than one female, older females will lay a greater number of eggs to younger counterpart of 11 on average.
Brightest fittest males win, not only in right colour but also defending territory or he might be out of luck. Earth's mating arena males have learned to use colour to attract love in nature! Females camouflaged for protection blend in quietly watching, choosing the right partner to ensure the species survive.
