There’s an entire literature discussing which animals – besides us, humans, are able to use tools.
Most authors also make a clear distinction between the animals which just pick an object and transform it into a tool by using it as such and the animals which actually transform the future tool according to the intended use.

The difference between using a twig ‘as it was found’ and sharpening it first with the teeth.

This morning, watching some birds while having my breakfast, I just realized that the vast majority of them are superb tool makers. Them birds, I mean. Not just the heavily publicized Caledonian Crows….

I repeat. Most of them.
Most of them are superb tool makers.

Most birds are nest builders.
In fact, they not only build houses, of sorts.
They are building uteri. Or uteruses, if you prefer this spelling. Places where eggs are laid and cared for.

What more elaborate tool is there?
