Allow me to quote from
that article about crows because I'm pretty sure you didn't click on it and I don't think you're worried enough about the secret plans of the crows: "they whittle branches into hooks and tear leaves into barbed probes to extract food from hard-to-reach nooks... New Caledonian crows are also innovative problem solvers, often rivaling
primates. Experiments have shown that the birds can craft new tools out of unfamiliar materials, as well as use a number of tools in succession." Unfamiliar materials! Rivaling primates! Hooks! Barbed probes!
