Bees building a nest

Bombus Hortorum building a nest under decking in my garden. This is the second nest as the original and larger colony was inside an abandoned Blackbird nest in a diseased bush and was disturbed when the bush was removed. Seems to be the most common bumblebee with no particular problems but even so I will make them a new house and re-site it somewhere appropriate close by. This variety is partial to Lavender of which I've got plenty in my garden.

Built a bee house to move the somewhere more appropriate. Following instructions I moved them late evening when they are all in the nest with plenty of nest material
