142 THE SCOTTISH NATURALIST 



This may be reckoned the end of the immigration ; for 

 on the 5th December, for the first time since the movement 

 began, no Waxwing was recorded, and thereafter the numbers 

 seen daily are insignificant, and show those slight fluctuations 

 which might be expected if we assume that the parties which 

 had arrived earlier were now scattering or scattered. 



Regions of Arrival and Incidejice of the Migration. — In 

 the majority of the great immigrations of Waxwings to 

 Britain the bulk of the migrants have landed on the east 

 coast of England, and, in comparison, the numbers recorded 

 from Scotland have been paltry. In the present case, 

 although the position can scarcely be said to be reversed, 

 the incidence of the migration fell much more heavily on 

 Scotland. As this difference is probably traceable to special 

 meteorological conditions, the incidence of arrivals may be 

 investigated a little more closely. If the country be divided 

 into broad regional areas, it will be found that the numbers 

 of birds, in round figures, recorded from each is as follows, 

 excluding casual records after the early days of December, 

 and clear cases of overlapping : from Scotland north of the 

 Caledonian Canal, including the northern and western Isles, 

 140; from the southern shore of the Moray Firth to the line 

 of the Forth and Clyde, 175 ; from the line of the Forth and 

 Clyde to the Border, 335. In England the distribution was 

 roughly: in the north-east, 95; north-west, 53; east, 43; 

 mid, 29 ; south, 26 ; and west, 8. 



It is apparent that in England the maximum arrival 

 occurred in the north, and that southwards the numbers 

 gradually dwindled. In Scotland, on the other hand, the 

 maximum occurred in the southern area, and the numbers 

 gradually declined northwards. Taking Britain as a whole, 

 therefore, we conclude that the main bulk of the immigration 

 landed in Southern Scotland ; and that, while flank move- 

 ments developed on both sides of the central area, the 

 greater number of the birds involved in these were carried 

 northwards of the main region of arrival. 



In the continuation of this article I hope to discuss the 

 causes of the immigration, and incidental observations 

 regarding the habits of the Waxwings in this country.
