135 THE BIRDS OF THE STOUR VALLEY (ESSEX ONLY) IN 1924 AND 1925. By WILLIAM E. GLEGG, F.Z.S., M.P.O.U. THE completion of my observations on the birds of the Stour Valley carries me a step nearer the realisation of my intention to make a survey of the birds of the Essex rivers, or, to be strictly correct, the Essex estuarial rivers. Notes on the birds of the Crouch and Blackwater have already been printed, so that this constitutes the third of the series. Some consideration of the physical features of the river is necessary. From the scenic point of view the Stour is very much ahead of the other Essex estuaries, in fact, if a coined word may be permitted, it may be described as "UnEssex." The fact that the reaches towards Dedham comprise what has been made famous as the "Constable country," would alone, in this respect, place this river in a prominent position ; leaving the Constable country out of the question, however, the scenery of the Stour would still take first place, although to the writer, the remoteness and seclusion of the bare marshes of the Crouch and Blackwater are preferable and never without beauty. It would be out of place to attempt a description of the river above Manningtree, but the pleasure of a tramp from there to Dedham by the field-paths through the meadows on an April morning, is very real. The river from Manningtree to Parkeston is picturesque. One associates with the Essex rivers miles of sea-wall and wide stretches of marshy meadows and saltings, broken up by a labyrinth of dykes or fleets, but within the confines of the river these features are absent from the Stour and it is with this in my mind that I coin the word "UnEssex." The waters of the Stour are mainly bounded by its own contours, which rise and fall in a series of undulations. At different points the erosive action of the water on the higher ground has produced sharp cliffs, especially at Wrabness, where they may rise as high as 80 to 100 feet. At several points the woods overhang the river, as at Mistley, Stour Wood, and the Admiralty ground, and long stretches of the shore are covered with bright shingle. With the water reaching to the edge of the cultivated ground the river does not offer much oppor- tunity for nesting. It is only when we leave the river behind
