THE WHITE WAGTAIL. 



Motacilla alba L. 



This species could be clearly traced along the western route 

 in three main immigrations. 



The first of these occurred in Devon on the 4th of April : 

 whether this was the arrival of a main body, which stayed in 

 the south for some days or of merely a few stragglers, was 

 not clear, for it was not until the 13th of the month that we 

 again heard of them, in Wales, from whence they reached 

 the Isle of Man on the 14th and Lancashire on the 16th. 



The second immigration arrived in Somerset on the 

 16th of April, Merioneth on the 19th and 20th, Denbigh on 

 the latter date, and the Isle of Man on the 20th and 22nd. 



The third immigration was noted in Somerset on the 

 27th of April, but the birds did not reach Merioneth until the 

 9th of May, Lancashire on the 11th, Westmoreland on the 

 12th, and the Isle of Man on the 13th. 



A few birds were seen in the eastern counties, but the 

 records were so disjointed that it was impossible to trace 

 any definite movement. A few were also observed near 

 Nottingham by a very competent observer between the 

 19th and 26th of April, though thei^e was no means of 

 finding out by what route they had arrived there, but there 

 can be little doubt that stragglers occurred in the south-east 

 and in the midland counties, and may have represented birds 

 crossing the country in a north-easterly direction.
