84 THE SCOTTISH NATURALIST 



May. 



A westerly type of weather prevailed throughout the 

 month, the influence of which is reflected in the migration, 

 which was normal and steady. There was a considerable 

 arrival of summer visitors in the first fortnight, but this 

 dwindled as the month progressed. A certain amount of 

 passage migration took place but nothing in the nature 

 of a rush ; winter visitors passed north in lessening numbers 

 during the month and some uncommon visitors are recorded. 



June. 



One or two late arrivals are recorded in June ; the weather 

 was dry and hot and the winds variable ; a little passage 

 migration is still recorded and late winter visitors still 

 lingered. Birds began to flock after nesting, and the first 

 indications of returns to the shores are seen. 



July. 



Up to the last week of the month the weather was hot 

 and dry, in the last week heavy rains fell ; the wind was light 

 and variable throughout the month. The movements in 

 July were such as one would expect to find at the season ; 

 there were returns of Waders and Gulls to the shore after 

 nesting, flocking of our own breeding birds and departure 

 of Swifts and Cuckoos. Very few arrivals of Waders from 

 overseas are noted. 



A ugust. 



After the loth of August the prevailing wind was from 

 an easterly quarter. There was a good deal of movement, 

 the usual autumn arrival of overseas Waders continued 

 throughout the month. A considerable departure of our 

 own birds is recorded and a certain amount of passage 

 migration is noted.
