The spring migration of birds over the British Islands has scarcely ceased, before the first signs of the autumn flight begin to be apparent along the coast. Of course, this early autumn migration is first noticeable upon our northern and eastern coast-lines. Certainly, by the middle of July, a few of the Arctic wading birds may be noticed on the shore, or flying south along the coast. Towards the end of the month, and early in August, the number of these returning migrants increases. Young Knots and Gray Plovers, with odd adult birds, appear upon the sands and mudflats. Almost at the same time we may notice the Common Sandpiper back again upon the shore, followed by Lapwings, Ringed Plovers, Greenshanks, and Curlews. Then various small birds begin to drift along the coast, on their passage south—Swifts, Wheatears, Willow Wrens, and Whinchats. Throughout August the migration of birds gets stronger and stronger, and towards the end of the month, and early in September, our own summer migrants begin to leave the country. Warblers and Swallows, Wheatears, Flycatchers, Thrushes, Wagtails, and Pipits, may be met with from time to time, along the coast, all bent upon early departure. The wide reaches of mud and sand, often so dull and uninteresting, and devoid of bird-life, in summer, are rapidly filling with a new population, Plovers and Sandpipers appearing upon them from day to day in ever-increasing numbers, whilst the seas near by are becoming sprinkled with the earliest hosts of Ducks and Geese. The Terns, once more, are on the move, this time flying south to warmer seas. With the advent of October, most of our summer birds have gone, a few belated Swallows and Wheatears, a few venturesome Chiffchaffs and Wagtails, being all that remain. All the autumn through, however, coasting migrants of many species—the same that passed north in spring—continue flying south. Most of this migration is from the north and north-east.
