Dr. von Heuglin states that this species is “a bird of passage in 
North-eastern Africa and Arabia, in February and March, and again 
from August to the beginning of October, partly singly, partly in 
great flocks, in company with other species.’ Mr. Blanford shot a 
female at Koomayli on the 2nd of February, 1868. 
Dr. Bolle (/. c.) refers to its appearance in the Cape Verde 
Islands in great swarms in April 1852 at Fuertaventura. They dis- 
appeared as suddenly as they came. The most extraordinary fact 
in relation to the migration of the present bird is its occurrence in 
Prince’s Island, on the West Coast of Africa. Here Mr. Keulemans 
shot it under the circumstances mentioned in the accompanying note 
with which he has favoured me :— 
** During the month of January I was living at a plantation about 
1500 feet above the sea-level, and I was one evening very much 
surprised to see a Swallow flying round my house. I had before 
often seen Swifts (Cypselus abyssinicus), but uever a Swallow 
before in that neighbourhood. As it was rather late in the evening, 
and I had no small shot in my gun, I was obliged to let it go, hoping 
to see it again afterwards. Fearing lest I might lose the chance of
