In the course of a visit to family Stehn on Farm Smalhoek some 30 km south east of Dordabis for a few days after Christmas in 2010, HS mentioned to NT that he had observed a group of White-backed Vultures eating plant material. The incident had occurred probably in late 2005 or early 2006 when HS had seen a group of about twenty to thirty White-backed Vultures on the ground eating the leaves one of the "slangkop" species. These birds thereafter regurgitated what appeared to be largely hair. HS identified the plant as Pseudogaltonia clavata (previously Lindneria clavata). There was no carcass to be seen anywhere in the immediate vicinity. Some sources maintain that P clavata is a poisonous plant causing, inter alia, diarrhoea, dehydration, hind quarter lameness, bloat and heart attack in livestock while other sources report that especially the leaves are eaten by game and livestock without negative effects. HS advised that the latter was also his personal observation having observed cattle eating small quantities of the green leaves and also dry leaves after the first frost in some years.
