The Swift, although one of the latest birds of passage to arrive and one 
of the earliest to leave, is found in suitable districts in almost all parts of 
the British Islands, with the exception of the Outer Hebrides, where it 
has only once been seen. It is somewhat rare on the inner islands, and is 
only an accidental visitor to the Orkneys and Shetland. It is rather 
common in the Channel Islands; but is said by Thompson to be absent 
altogether from certain parts of the west of Ireland. 
The Common Swift has a very extensive range, reaching from the 
Atlantic to the Pacific. In Norway it has been found breeding as far 
north as lat. 69°, and has been seen up to lat. 70°. It occasionally strays 
as far as the Faroes, and is also an accidental visitor to Archangel ; but 
has not been found in the Ural Mountains beyond lat. 60°. It has occurred 
once at Omsk in lat. 55°, and breeds regularly in Dauria in lat. 50°. It 
also breeds in Mongolia and North China ; but has not been recorded from 
Japan. It is a summer visitor to the Canaries; but is a resident in 
Madeira. It breeds throughout South Europe and North Africa, being 
most abundant in rocky districts. It is a common summer visitor to
