Yesterday I noticed the female blackbird taking dry grass cuttings into a corner of the garden, where there's a dead leylandii covered in honeysuckle, which seems a very good place to nest. It's only a couple of metres high, so she's quite low down.
I want her to be happy there, but it's in one corner of the only border I can grow stuff in - landlady's leylandii all along the long wall at the back, one side of the garden is the house, and the other border is fully in shade. How far should I stay away so as not to upset her?
