CERTHIID#—MOTACILLID th 
Family CERTHIIDA., 
50. CERTHIA FAMILIARIS, Linn. T'ree-creeper. 
Resident in the best wooded districts, but not common. Has been 
obtained at the Spurn, Easington, and in the Farne Islands in the 
autumn. 
Family MOTACILLIDA. 
51. Moracinia Lucusris, Temm. Pied Wagtail. 
Resident and nesting. The bulk go south in the autumn, but a few 
always remain during the winter. The spring immigrants arrive in 
March, and the great body of birds leave in September. 
52. Moracinia ata, Linn. White Wagtail. 
Occasionally in the spring, but later than the pied wagtail; has 
nested in the district ; March, April, and May are the months in which it 
has chiefly been observed as a migrant. 
53. MoractnLa MELANOPE, Pall. Grey Wagtail. 
A common winter visitor to our streams and becks, arriving in Sep- 
tember and October; leave again in March. In 1897 a pair nested in an 
ivy-covered wall of the house at Great Cotes within four feet of my 
library window, and brought off four young [‘Nat.,’ 1897, p. 287; 
‘Zool.,’ 1897, p. 274]. 
54. Moracinna FuAva, Linn. Blue-headed Yellow Wagtail. 
A pair were seen in June, 1895, on several occasions by Mr. Hewetson 
near Kilnsea Beacon during the time he was excavating a tumulus, and he 
had no doubt they were nesting. April 17th, 1898, an adult male at 
Easington following a plough. In 1894 Mr. Haigh shot the immature 
bird on North Cotes fitties. Probably occurs frequently on migration 
in the autumn at the time the yellow wagtails are moving, from the 
fact that many of the supposed young yellow wagtails have a very 
conspicuous eyestreak varying from pure white to buff. 
55. Moracinua rat (Bonaparte). Yellow Wagtail. 
Seldom before and seldom later than the third week in April; 
generally distributed and nesting in dry situations. Leaves in Sep- 
tember, when there is an immense migration along the coast to the 
south of home birds and foreign arrivals from the continent. 
56. ANTHUS TRIVIALIS (Linn). Tvee-Pupit. 
In April, from 1864 to this date, arriving from the 5th to the 22nd, 
plentifully distributed in the best wooded districts. Depart in Sep- 
tember, when they are often very numerous on the coast. 
57. ANTHUS PRATENSIS (Linn.). Meadow-Pipit. 
A few resident throughout the year, their numbers being greatly aug- 
mented in the spring in early March; these latter leave about the end of 
August and September, at which season there is for days a continuous 
movement along the coast to the south.
