north as the Arctic circle. They winter 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.
