Re: Peter Kevans' obs on foraging distance.
    While doing some observations this past summer, with tagged bees in a small
 nuc amongst a field of blooming white clover, I found that bees do forager tho
se flowers close to the hive, I even noticed that some bees that cannot fly(due
 to experimental manipulation) even jumped flower from flower right near the en
trance (I recorded about 5 bees doing this)!   although I am not sure if given
a choice bees would choose the further one, which seems to be counterintuitive
(that is,to human's intuitive, of course).
