I found a reference to this work while reading Australian Birdlife magazine - a clear example of serendipity

It comes with the usual warning about making your head hurt

Interesting, was a long article to just say less uv passes through the leaves than green light. Thus the reflected UV light difference is used for contrast vision of the birds.

I'm only a chemist, but it often seems to me as if many papers in this area are answers searching for questions. :rolleyes:

That's how mathematics is sometimes done! The theory ("answers") progresse beyond the practical applications ("questions") of it. Yet eventually, it seems, the theory explains something somewhere in physics/engineering/etc.

This is an interesting paper, Dave. I read a lot of it, then got a bit bogged down. (But that's ok.)

Speaking of bird vision. This is just being discussed today here: https://www.ultravio...berry-question/
