Bee hive yourself

Amazing what you can learn while ripping up privet. Yesterday, on my return from carrying a chunky stump to the discard pile, I found a bumble bee sitting quietly on the soil beside a bumble-bee-sized hole.

She looked pretty dopey. I thought how lucky she had been to avoid being squashed while I was yanking the privet stump back and forth to dislodge its roots, but until then I hadn't realised that bumble bees hibernate (a fact later confirmed by our resident Keeper of the Zoological Knowledge - aka Nat).

Their post-hibernation warm-up routine was fascinating to watch too. A few minutes of abdominal exercises (a slight pumping action visible) followed by a couple of tentative - and very short - hovers, only a few millimetres above the ground, to warm up the flying muscles. And then a lazy figure-of-eight flight, gradually increasing in both height and area as the long-unused wings remember their skill and strength, until eventually sufficient altitude was gained to make it over the low wall (see photo on previous blog entry) and cross the lane to the conifer hedge on the other side which at that time of day was in full sun.

The bee sat on that hedge for well over half an hour, soaking up the rays. Clearly a much easier way of warming up than all that tiring flying, especially when you're running on the food reserves that have brought you successfully through a few months hibernation.

Nature in the raw - in our front garden! Brilliant.
