Off The Visible Spectrum

[poliphilo]

Male and female blue tits look just the same to us but not to one another. That's because they can see colours we can't- and male blue tits carry brighter patches of ultra-violet.

(I got this info from Chris Packham's excellent TV show World's Weirdest Events.)

Ultra Violet is a real colour- or range of colours.  The same goes for Infra Red. But I can't see them. I can't even imagine them. I find that very hard to get my head around.

Insects also see way into both spectra and therefore see plants and flowers in an entirely different way to us!

This is how a bee sees dandelions, for example:

I think I prefer the yellow version.

It shows that our visual range is limited and that other creatures do see things differently to us.

It must be awfully chilly over there to make your tits blue.
