Migration Notes Month by Month. 



January. 



January was unusually mild and consequently no weather 

 movements are recorded. The principal items of interest 

 are the unusual number of Pied Wagtails reported and the 

 continued occurrence of Gannets on the Bass Rock. One 

 or two Waxwings were observed during the month. 



February. 



The weather throughout February continued mild and 

 migration seems to have been perfectly normal, consisting 

 largely of the return of partial migrants to their breeding 

 grounds. 



March. 



In March the movements continued on normal lines; 

 there are more notes of the return of partial migrants ; 

 the earliest summer visitors are reported, and winter visitors 

 were making their way north. The month was breezy, the 

 prevailing winds being between west and south. 



April. 



The wind continued from the west and south up till 

 the 1 2th, after which the weather tended to be more of a 

 northerly type. There were some early arrivals of summer 

 visitors ; these became numerous as the month advanced 

 and the arrivals were considerable and widespread. A 

 good many winter 'visitors were on the move but little 

 passage migration is recorded.
