I have a few habitat areas which creatures can use for homes which I try not to disturb too much.
In my garden the Bumble Bees have decided to ignore those and have chosen a spot under the path. Right next to a clump of Chives they have an entrance tunnel.
Some are foraging in my garden others are going further afield in two directions. They go way out of sight and return heavily laden with pollen.
I decided they had better have a house sign so that no casual hoeing goes on and causes aggro.
brilliant idea!
I used to have a couple of nest boxes set up with miniature cameras and one spring a newly emerged queen bumble bee ousted the pair of blue tits who had begun making their nest and i was able to show the local kids what happens in a bumble bee colony.
It really is quite fascinating!
