 May the birds which but a week previously were 

 circling round the Moorish towers of Spain. Its

 journey in spring, and in this respect it differs in 

 habit from many other species. 2 



In India its place is to a certain extent taken 

 by a non-migratory species, Cypselus affinis, but 

 it has nevertheless been met with in that country. 

 An Indian specimen was received from Dr. 

 Jerdon, presumably from the north-west. 3 It 

 has also been forwarded from Afghanistan, 4 and
