The nest was composed of twigs and uncompleted. Returning on April 25th, I found it lined with fur and feathers and containing five typical Jackdaw's eggs. The old birds circled overhead in alarm and returned to the nest when we left the tree. This nest was apparently a new structure and not a renovated Crow's nest.

There was a rookery on the side of the Downs about 600 yards away, but no hollow tree cr church tower within a mile. R. C. C. Clay.

During the nesting seasons of 1920 and 1921 I spent much time watching Wheatears {OEnanthe oe. cenanthe) on the South Downs near Seaford, Sussex, to find nests in order to ring the nestlings. The nests in these parts are in rabbit-holes and short scrapes. Each y^air of birds appears to have at least one warren in its territory ; the nest, however, is never actually in the warren, but is generally twenty to thirty yards away, though I have found one or two distant only five yards. On the average the nest is about a foot down, though in one case it was over two feet. I believe that, as a rule, the male gives the alarm as soon as anybody comes in sight, and the female then flies off the eggs ; so my usual practice was to walk about the ground until I saw the female, then retire to a convenient distance and watch her through glasses. After five to twenty minutes she would go back, invariably flying the last twenty or thirty yards and alighting inside th
