Bumblebee nests

Bumblebees are in decline across the country, but they seem to be having a good time here. We know of at least 3 nests this summer and the garden is literally buzzing. And one species (not the one in the picture I’m afraid) is a bit unusual. We’re pretty sure it’s Bombus hypnorum, the tree bumblebee (because it nests off the ground?). It has only been known in Britain since 2001 but seems to be doing well. Here’s a clip of bees returning to their nest in crates in the wood shed. Not hugely photogenic perhaps, but worth recording. And yes, we’ve submitted the record to BWARS, the bee wasp and ant recording society.
