Jackal Buzzards feed on small mammals, carrion, insects and reptiles (Oberprieler and CIllie, 2009). They ther fulfil an important role in managing rodents and other species affecting farming practices.

This incident happened about ten years ago when my mother, Judene Botha, went for her daily walk with our dogs. She came across a Jackal Buzzard struggling on the grass as if something was keeping it from flying off. The dogs were already very excited and posed as a hazard hurting the bird. Judene decided to take them home and went to fetch Philip and a visiting friend. They came to inspect the situation and realized the Jackal Buzzard was being held down by a Mole Snake Pseudaspis cana, having its body

around the buzzard’s foot (Fig 1) and already halfway down its hole.

Both parties were in trouble, as the buzzard could not escape, and clearly the Mole Snake was also not giving up the fight.

Some would say one should never interfere with nature’s course and there may be different opinions about the situation, but Philip decided

Fig 2 – The ongoing struggle between the bird and the snake Incidents where predators face dangerous risks from getting

by their prey are very rarely documented. This can however be detrimental concerning foraging costs and taking risks. In raptors, several injuries have been documented caused by small carnivores and included dislocated joints, broken toes and flight feathers as well as injured eyes (Mukherje and Heithaus, 2013).

One would not expect that, knowing small mammals and reptiles being regular prey for Jackal Buzzards, that a Mole S
