We spotted the large but simple nest at about 100m from the road between Main Camp and Nyamandlovu pan in Hwange National Park, (Zimbabwe) when we visited this park last July. We looked for its owner for a while and, a couple of hundred metres ahead, we found a suspect: an adult Martial Eagle perched on a large acacia tree at about four metres from the ground.

We stopped to take pictures and, as usual, we took the first one from a prudent distance and with the engine on, before getting a bit closer for better ones.

A subsequent Internet search did not reveal a record of such behaviour. Although I believe it to be known to specialists in birds of prey, I reported it here just in case as it was an interesting, if anxious, observati
