Fork-tailed drongos
(Philippe Clement / NaturePL.com)

Fork-tailed drongos in the Kalahari Desert act as sentinels, scanning for predators and producing regular “all clear” calls so other birds can spend more time looking for food. It’s cooperative behavior, but it’s also a protection racket: drongos make false alarm calls and snatch the abandoned food.
