A rare morning of calm weather and the sky was full of Swifts again. Our unusually marked partial albino Swift found a potential mate and succeeded in attracting it back to nest box 3. They spent an hour there this morning, calling softly to one another. I now think that the partial albino bird is a female based on the calls I have heard it make. This is interesting because in this case at least the female has selected the nest site. In fact she did this back in June 2010, quietly prospecting alone. She arrived on 11th May this year and has roosted in the box alone every night, but will she be alone tonight? Watch this space.
