I at once recognised that it was one of the feeding-platforms referred to by Mr. Christy in the paper he read before the Club on the 25th January last.1 As it was not convenient to remove the platform at the time, I left it and forgot all about it, so that it remained in the hedge until last August, when I cut it out. The seeds and droppings had by then been washed away by rain, but I exhibit it to-night for what it is worth. [Mr. Nicholson has presented the specimen to the Club's Museum.

THE following notes on Essex ornithology are based on observations made during the past ten years in that part of the county lying south of a line drawn from Harlow to the Blackwater. At one time or another, from 1909 to 1919, all parts of this area have been visited; but, on some occasions, the object of such excursions has been other than ornithological work. In going through my notebook I find that many of my records, interesting enough to myself, are too trivial for pub- lication here—they contain nothing new, of county interest at any rate; some have already been published elsewhere, with little or no mention of the actual locality where the observations were made; and not a few of my minor discoveries have cancelled themselves after my recent careful reading of Mr. Miller Christy's two chief publications on the ornithology of the County1, which, I need hardly add, have been freely used during my residence in and near Essex. Best acquainted with a northern avifauna, I find Essex to be extremely rich in terrestrial birds; but, on the contrary, my success with aquatic species has been remarkably poor. More than once I have spent a whole day on some desolate marshland of the southern or eastern coast of the county without meeting 1 Birds of Essex, 1890, and "Birds" in the Victoria Hist.
