Luckily there are other sorts of quarry about. For a start, a quarry can be more or less anything you're trying to find. For a hedgehog that'll include slugs, and for a robin it'll include worms.

Mm. Nice slippery slurpy worms. Yum!
Even easier, a quarry is a square or diamond shape. This is why quarry tiles are so called, and not because the clay of which they are made has come from a quarry, though it probably will have done.
Lastly, a quarry can be a small diamond-shaped pane of glass:

or a square-sectioned cross-bow bolt.
Right. So I'm going out to see if I can find a worm, then.
Spot the frippet: quarry. The big hole word comes from the Latin quadrāre, to make square; the catching prey word comes from the Old French cuireé, what is placed on the hide [of an animal] ie entrails, from the Latin corium leather, probably with a bit of the French coree, entrails, mixed into the word; and the square shape comes from the Old French quarré, from the Latin quadrus, square.
