This headline sounds like click-bait. I can’t help that. Sometimes the world is click-bait, and the headlines have to follow its lead. What this bird does is unbelievable... in that researchers had to do a serious study to actually believe it.
I recently wrote a piece about a bird called the greater honeyguide, whose chicks brutally murder those of other birds. But honeyguides are better known for a more helpful behaviour – leading humans to bee hives. The people break open the hives and leave behind an otherwise inaccessible piece of honey for the bird.
