THE NIGHTJAR. 



Caprimulgus europceus (L.). 



This species was unrecorded at the lights, and owing to the 

 scanty nature of the inland reports it was almost impossible 

 to define the area o£ its entry and subsequent movements. 

 It seems not improbable, however, that it arrived singly 

 or, at most, in very small parties along the greater part 

 o£ the southern coast-line. 



The earliest arrival reported was in Yorkshire on the 18th 

 of April ; and an increase in numbers took place in that 

 county a week later, while solitary birds were observed in 

 Hampshire, Wiltshire, Surrey, Derby and Lincolnshire on 

 the 26th, 29th and 30th of the month. At the end of the 

 first week of May they commenced to arrive in greater 

 numbers, and in the course of the next fortnight had spread 

 over the country generally. Nightjars were nesting in 

 Berkshire on the 13th of May.
