north as the Arctic circle. They Avinter in the tropical regions of Africa 

 and Asia, and are especially common at that season in the islands of the 

 Malay archipelago. Two species apparently migrate south instead of 

 north to breed, and resort to the swamps of Australia for that purpose. 

 Seven other species appear to be non-migratory one having found a 

 permanent home* in South Africa, and the others in the islands of the 

 Pacific, from the Carolines in the west to the Marquesas in the east of that 

 ocean. Five species are regular summer visitors to Europe; and the range 

 of two others extends as far as the extreme south-east of Europe. Three 

 of these breed in the British Islands, and two are accidental visitors.
