Just been washing up and caught the end of a prog on radio4 about bees, very interesting it was. There was a bit about bees having 'sussed' global warming and warmer winters and so they keep looking for flowers during winter. I think the podcast is the whole prog, the bee bit was at the end - starts at about 14 minutes in.
"Warm flowers make for happy bees - Flowers use colour, shape and even a special way of harnessing heat from the Sun to make the perfect environment to compete for the pollinating power of bees.
Quentin Cooper talks to Heather Whitney and Lars Chittka to find out more about how flowers advertise themselves to bees.
Also why bees are cognitive giants who can navigate an area the size of the 'congestion charge' and memorise landmarks on the way with a brain the size of a pin head."
