O'Hara et al. (Current Biology, 31, 4512-4520, 2021) show that wild Goffin's cockatoos (Cacatua goffiniana) exhibit tool-related abilities at levels previously demonstrated by nonhuman primates or, in birds, only by those raised in captivity. Their data provide information about the cognitive and ecological underpinnings of this behavior and provide the impetus to search for additional examples of convergent evolution in avian and mammalian lines.
