You're a bird, flying in looking for tasty morsels in the shrubbery. Ooh, what's that, something fluttered by and landed? You investigate...sheeeyit there's a sharp-eyed mammal staring back at you!

The details and the subtlety of the "eyes", formally known as ocelli, are quite astonishing when you think about it. They have "irises" and "catchlights" to make them look like real eyes and from this angle eyebrows and a nose below!!!
@sciencebase I remember reading about work that showed that without the catchlights, they were far less effective. Don't recall how they did it though.
@sciencebase Whilst you're there, do you know what pica means as in Na pica sulphate?
