At Chudop, shaking a Ring-necked Dove to death. Our local guides all said that this was the first time that they had ever observed, or heard of, a Kori Bustard hunting and killing a dove. Keith Kennedy's photo.

At Chudop, hunting and killing Ring-necked Doves. We watched a Kori Bustard not once but twice grab a Ring-necked Dove at the edge of the water hole, shake it to death, and start eating it before a Black-backed Jackal moved in and snatched the dove away. Both our Namibian guide Usko and our South African guide Stu Porter said that they had never seen such a thing. Later in our trip at Tswalu Kalahari Reserve, two of the guides there, Cameron, who is a birder, and Kosie, said they had never heard of a Kori killing a dove. Matt Prophet, our birding guide in the Western Cape, concurred. So how unusual is it for a Kori to hunt doves? Did this Kori learn to hunt by watching the Black-backed Jackal hunt doves? This observation does raise questions.
