THE NIGHTJAE. 



Caprimulgus europceus L. 



The records for this species are so few as to throw but 

 little light on the way in which the Nightjar arrives in 

 this country. During the last week in April and the 

 beginning of May a few scattered birds were seen in 

 Somerset, Lancashire and Wales, but it was not until the 

 16th of May that the immigration of this species may be 

 said really to have begun. 



On May 16th and 17th there was a sudden increase 

 in the records, at first chiefly in the west, but after 

 the latter date on the eastern half of the south coast, 

 evidently indicating an arrival along the southern sea- 

 board. (Dorset to Sussex.) 



The western birds gradually spread through Wales and 

 along the Welsh border to Cheshire, Lancashire and York- 

 shire, while those that arrived more to the east populated 

 the south-eastern corner of England. 



The immigration was evidently soon completed, and no 

 subsequent movements appear to have taken place.
