Do snails eat birdshit?

In one of my little wanders around the garden as an interlude I spotted a snail having a go ad some bird shit.

So, do they eat it? I’m not going to spoil speculation by trying to look it up, obviously. And given that it’s a snail I can’t quite insist that it found it to be fingerlickin’ good.

But I don’t know what snails do eat – something about their mouth being in their stomach or something – and thus whether bird poo would be on the menu. For all I know soon to be guano is sufficiently acerbic to melt them.
