The Goosander nest in a Tawny Owl chimney which we have been monitoring now for 4 weeks (and the owner of the house for some weeks longer) was empty today. There was one dead duckling that obviously couldn't get out of the tall box, but the remains of an estimated 10 eggs. It was some distance from any stream, but hopefully she and her brood made the trek across a field and through a wood to a tributary of the Irwell.
