In 2011 and 2012, Great Tits nested in my specially constructed nestbox fixed to the outhouse next to my old studio. Last year, a small colony of Tree Bumblebees took over the premises. This year, the nestbox is crammed full of the little flying, furry humbugs, as you can see from the photos above. The Tree Bumblebee only arrived in Britain in 2001, but has since spread very well, and have made a great home in our garden. This year we have planted a wild meadow, so the Red Clover flowers are providing a rich sauce of nectar for these charming little insects.
