MOTACILLIDAE—WAGTAILS. 97 though I have never personally identified it with certainty, and the only actual record of its appearance here I have been able to meet with is the following : Mr. Joseph Clarke, writing at Saffron Walden about 1845, says (24) of the "Pale Wagtail, Mot. alba, Tem.," that it "breeds here occasionally. A whole brood of five, with the old one feeding them, seen at Wenden, 1836, by S. Salmon and self." It has also been known to breed in several other southern counties. Canon Babington says (46. 248) that two specimens, one in winter, the other in summer plumage, which " were in all probability obtained in the neighbour- hood of Sudbury," are in the King Collection, passing as Pied Wagtails. Pied Wagtail: Motacilla lugubris. Locally, " Nanny Wag- tail," and " Dish-washer." A common resident, though partially migratory, most of our birds going south dur- ing winter. Mr. Buxton says (47. 89) that in Epping Forest it is " a common resident." He adds : " The greater number go south, to return about the end of February, dressed in their summer plumage. Those that re- main with us, retain their winter garb until the spring is farther advanced." Many certainly do leave us in winter, but not all, as I saw one here on December 8th, 1879, the day after the very severe frost. Mr. E. Gottwaltz records (29. Feb. 5, 1876) that for three winters one amused itself almost daily by tapping on a window of a house at Great Baddow, a strange proceeding which has before been recorded of this and other species. Grey Wagtail: Motacilla melanope. An uncommon autumn and winter visitor. I have no knowledge of its having ever bred with us. Mr. Seebohm says (45. ii. p, 204) : " I first became acquainted with these charming birds in the neigh- bourhood of Saffron Walden. Be- tween this town and Audley End lies Lord Braybrooke's Park. A winding brook runs through it, by the margin of which you might stroll any winter's morning with the certainty of seeing one or two pairs of Grev Wagtails. They were regular winter migrants, ap- pearing about the beginning of October and disappearing as regu- larly towards the end of March."
