Ornithology of Corsica. 
visitor to Sartene and Bonifacio, though not resident there. 
It has apparently extended its breeding-range northwards of 
late years, and has now established itself at any rate as a 
summer visitor in the low-lying country to the south-east 
of the island, where a good many scattered pairs breed in 
holes of cork-oaks. First eggs found on May 9. 
12. Oriolus oriolus (L.). Golden Oriole. 
Visits the island on passage only. Wharton saw large 
numbers, chiefly males, at Biguglia on April 17, but few 
afterwards. Whitehead records its first occurrence on 
April 24; but he saw few pass, and the last on May 29. 
13. Coccothraustes coccothraustes (L.). Hawfinch. 
Local names: Capi grossi (north), Schia korino (south); 
Pizzigone (Giglioli). Resident and not uncommon, but 
owing to its retiring habits not often seen. It breeds not 
only in the low ground, but also in the mountain forests to 
over 3000 ft. at least. Jesse records it from the Bastia 
market, while Backhouse, Trevelyan, and Parrot obtained 
specimens from the Ajaccio market in winter. Whitehead 
describes it as fairly common, but very local. He only saw 
one bird on the west coast, but took two nests with fresh 
eggs on May 16 and an incubated clutch on June 6. I 
found nests in 1908 and 1909 in lichen-covered cork-oaks 
with full clutches on May 27 and 28, and also observed the 
birds in the alder groves among the high pine-forests in 
the middle of May. (For notes on Corsican specimens of 
this species, see Hartert, Vog. pal. Fauna, i. p. 56, and 
Parrot, Ornith. Jahrbuch, xxi. p. 127.) Average size of 
9 eggs, 23*22 X 17*31 mm. 
14. Ligurinus chloris chloris (L.). Greenfinch. 
Local name : Verdone. A tolerably common resident in 
the hills as well as on the low ground. Parrot records this 
species under the name of Chloris chloris aurantiiventris 
(Cab.) with a query (?), but all the breeding birds seen by 
me were obviously duller in the colouring of the under 
surface than Spanish birds. From the wing-measurements
