Yeah, he looks a bit like a musician. ;-) David Attenborough has done a retrospective, and he is obviously getting close an age when he can't do all the travel etc.
This was a cool report - bumble bees can "see" the positive charge of flowers!

Remember - plants generate electricity at the cellular level - this is how they do photosynthesis. So, this is probably how the flowers become positively charged; and the bees themselves are negatively charged (caused by their flying), and the pollen is attracted to them. Cool stuff.
