A few to confirm ID - Plant, Skull, Track & Sign.

This one threw me, can you get white violets?

I'm thinking this is Pig because the bit (whatever it's called) below the eye socket looks too thick for sheep. Edit* 'Zygomatic arch' - just looked it up.

Found beside a stream, not sure what this track is. I'm thinking moggie because there are a few ferals about, but not seen any this far out.

I'm always walking past this stone
and doing a double-take. Is that rodent marks, if so, why?

Yes you can get white violets.

Yep, we have them in the garden. They may be scented, you can get quite a strong sweet violety smell off them when they're warm.
