typical of these coasting migrants, and those that may be readily distinguished, are such species as Whimbrels, Ringed Plovers, Sanderlings, Stints, Skuas, and Curlew Sandpipers. Whimbrels are very regular in their appearance, arriving at the end of April, and the migration continuing through May. Early in March, on our southern coasts, the purely summer visitors begin to be seen, Woodcocks and Pied Wagtails, amongst others, making their appearance. Towards the end of March, or very early in April, the first of the purely southern species reach us. Two of the most familiar are the Wheatear and the Chiffchaff; Ring Ouzels, Willow Wrens, and Yellow Wagtails follow them closely. As April passes on, the numbers of our summer migrants increase; Whinchats, Redstarts, Wrynecks, Cuckoos, Whitethroats, Blackcaps, Swallows, Martins, and so on, appearing in force. Towards the end of the month, and in May, Terns, various Sandpipers, Turtle Doves, and Quails, may all be found upon the coasts on their spring migration. Among the last to appear are such species as Lesser Whitethroats, Spotted Fly Catchers, Garden Warblers, and Red-backed Shrikes. This spring migration of birds along the British coasts lasts for a period of quite four months—from February to the end of May, or the first week in June. Some birds may be observed on passage almost throughout this period; others not more than half this time—especially the Warblers, Wagtails, and Pipits—others, yet again, complete their migration in a month or less, amongst these being the Red-backed Shrike and the Greenshank. For the spring migration of such species that visit the British Islands to breed, the southern coasts, of course, are the best points of observation—none of these birds breed south of their point of entrance to our area, as they all reach us from winter quarters in more southerly latitudes than ours.
