98. RiPARiA RUPESTRis (Scop.). Ciag-Mai'tin. 



Local name : Rondlna (Giglioli). 



Not an uncommon resident, but subject to local movements 

 according to the seasons. During tlie summer months, 

 and up to December, according to Wharton, it haunts the 

 mountains, and is generally to be met with in flocks, hawking 

 near some sheltered and sunny clump of rocks. On raw and 

 misty days it will descend almost to the plain even in summer, 

 and from December to April small parties and pairs may often 

 be met with near the coast. It breeds in colonies among 

 the mountains, and is very common in the great gorge 

 between Ghisoni and Ghisonaccia. Here Playne noticed 

 buikling going on in April, and Whitehead found fresh eggs 

 on jMay 13. Of two si)ecimens obtained by Parrot in winter, 

 one was much darker than the other, and he suggests that 

 the lighter-coloured birds may eventually prove to be winter 

 visitors from the Continent. Arrigoni's Coti/e obsoletasarda 

 (' Avicula,' 1902, p. 103), which was described from a winter 

 bird, is evidently a very light-coloured Crag-Martin. 



99. Apus melba (L.). Alpine Swift. 



A summer resident in small numbers in the mountains, 

 occasionally descending to the plains ; Whitehead first 

 noted it on April 25, 1883, and April 10, 1884, while Playne 

 met with it on April 10. Early in June Whitehead found 

 it nesting in inacessible rocks in the mountains. On two 

 occasions I met with this species on the east coast : on 

 May 10 a single bird was flying with the Common Swifts, and 

 on May 29 Read and I noticed five hawking over the coast- 

 road from Ghisonaccia to Bonifacio.

Swifts are exceedingly common summer residents in 

 Corsica, and are as much a feature of the landscape
