breed within the Palzearctic region ascend the Himalayas until they reach 
an elevation where they can enjoy a Palearctic climate. The southern 
winter range of the genus extends in Africa to the Cape of Good Hope, 
and in Asia to Ceylon and the islands of the Malay archipelago ; but no 
species has as yet been found in Australia. Six species breed in Europe, 
and many more are accidental visitors on migration. Of these, three are 
regular summer visitors to our islands, and a fourth has accidentally 
visited our shores.
