Nature’s solar panel

The fine weather continued on Saturday although the sunshine was far more hazy than the last few days.

Whilst we were at Fairburn Ings on Friday we noticed that numerous black swans had one leg over their back, swimming with just one leg. Turns out they use their foot a bit like a solar panel to warm up their body temperature, the really clever bit is they can reverse the process and cool down rather than warm up. Brilliant!
