Our female swallow has a buzzing visitor...

Tree bumblebees, Bombus hypnorum are known for their love of using old bird nests and bird boxes for their own nests. We had a tree bumblebee nest in the garden of our last house - it was great fun watching them coming and going with such purpose.

Our swallow was interrupted during her brooding at the weekend by a tree bumblebee! Clearly the eaves of our shed are prime real estate - for swallows AND bumblebees!
