So that empty nest we noticed when we moved in 6 months ago is now occupied. We think she is the mate of the little guy with the red plumage. Interestingly, we haven't seen much of him lately. Perhaps he's done a runner. Anyway, Mrs Bird is always there, looking out at us, or sitting on the edge of the nest with her arse in the air and her head down in the bottom of the nest arranging things. Perhaps she is turning her eggs.
