This week, Malcolm stumbles across a science paper from the 1970s about a graduate student with a really extraordinary and really specific ability.
You can read the paper from this story (heads up, if you're on a university campus you should be able to access it for free, but if you're not, you'll probably have to pay to access it. If you're really curious, email us.) But for free you can see some of Dafila Scott's artwork on her website. And the Wildfowl and Wetlands Trust website has a list of nature reserves (including Welney) that you can visit, if you live in the UK.
And finally, this is a Bewick's swan.
Music in this episode was composed by Malcolm Rosenthal. Artwork was drawn by Jackie Sojico.
