nbx / oaw[b&w] / gdn - bee's bum

During the spring of 2021, this box was inspected by several birds, but none took up long term residence. However, during May and June we noticed that a bee colony had taken over. Most of the day, two or three bees would fly around on "guard duty" - intercepting incoming flights - and my ears if I got too close ! This is one worker bee just entering the nest box.
Later, in winter, I'll have a look inside ...
