AB (again)

I know I have done these hives before
here, but it was a sunny spring day today and I needed to get out of the office for a little air so I paid them a visit. I don't think they are the same ones as last time.
Big Bees


More bees
here
and here
more here
This is not a bee, it is a strange building I found in the field next to the bees. It has no doors or windows.... What is it I wonder?
Here it is from space..

Hopefully another sunny blip tomorrow ;)

Cheers
