Here's my digital rendition of the male Black-necked Agama.... It is a species of tree agama that measures about 20 cm in length. It is native to East, Central and southern Africa. Its largest continuous range is in southeastern Africa, and it occurs at high densities in the Kruger National Park. It is found in Eritrea, Somalia, Ethiopia, Sudan, South Sudan, Uganda, D.R.C., Kenya, Tanzania, Zambia, Malawi, Mozambique, Zimbabwe, Angola, Botswana, Namibia, South Africa and Swaziland. They form structured colonies with a dominant male, several females and juveniles. The males defend territories and engage in combat. Although mostly diurnal, they sometimes exhibit nocturnal activity. It adapts readily to the vicinity of human habitation. They are classic ambush foragers which spend only 4% of their time moving. This involves an average of less than one movement in two minutes. When stationary, the adults position themselves on lateral branches (42% of the time), on tree trunks (35%), or occasionally on the ground (23%). They subsist on an insect diet, consisting of orthopterans, beetles and ants. They also eat millipedes, which other lizards tend to avoid. The juvenile’s diet is dominated by ants.
