BIRDS 



263 



This is a common bird on most of the islands of the archipelago, 

 rare only on Charles and Albemarle. This may be due to the number 

 of dogs and cats on these two islands, since the species nests on the 

 ground. The birds seem to be more or less migratory, for during 

 January and March we saw^ only one or two doves about Tagus Cove 

 on Albemarle, while in June they were not infrequent here and at this 

 time we often saw small flocks at Turtle Point just north of Tagus 

 Cove. 



One nest was found in April on James Island. It consisted of a 

 few straws and leaves lining a cavity in the surface of a rough lava 

 bed. The nest contained one egg ; the female was collected and an- 

 other egg was found in the oviduct nearly ready to be laid. The first 

 one is dull white, oval, and measures 27.5 x 22.5. On Barrington the 

 doves were found nesting during the latter part of May. The nests 

 were all on the ground between blocks of lava, and contained each 

 two eggs like the one from James.

 a larger body, longer wings, and a longer and heavier bill. The wing
