PIED WAGTAIL. GREY WAGTAIL. 103 



in Devonshire, in 1859, a most undoubted arrival of 

 migratory specimens appeared on the morning of the 

 20th of March. The grassy slopes in front of the sea 

 were covered with them till late in the day, and so 

 unusual was their appearance in such quantities that 

 they attracted general attention ; but on the next morn- 

 ing they had passed on, and only a pair or two as usual 

 frequented the " Denes," nor did I subsequently observe 

 any similar accession to the ordinary number of residents. 

 I may remark also that these were all pied wagtails, not 

 a single white wagtail (M. alba) appearing amongst 

 them. It has been more than once questioned in the 

 " Field" of late years, whether the pied wagtail ever 

 perches on trees : that it does do so, occasionally, I can 

 speak from my own observation, as well as on fences, 

 walls, and railings, but when observed on the branches 

 of trees or shrubs, it is generally at the close of the 

 breeding season, when the old birds are accompanied 

 by their young broods. I cannot ascertain that the 

 continental white wagtail, the true M. alba of Linnseus, 

 has ever occurred in Norfolk. 



MOTACILLA BOARULA, Latham. 

 GEEY WAGTAIL. 



A regular spring and autumn migrant, though not 

 in large numbers, appearing generally in March and 

 October; but at neither season remaining long in this 

 district, and but few specimens, at any time, are found in 

 the hands of our bird-stuffers. A male in my collection, 

 killed at Boyland on the 13th of March, 1863, has 

 nearly completed its summer dress, and Mr. Spalding, 

 of Westleton, has also a male, killed by himself at 

 Ditchingham, some years ago, in the month of May,
