Ornithology of Corsica. 
smaller than that of the Sardinian Warbler and may be 
found in cistus or in thick bushes, such as myrtle, but not 
at any height from the ground. The eggs are three or, more 
generally, four in number. Whitehead took his first nest on 
May 6, but most eggs are laid during the latter half of May. 
Not a single egg out of thirty-nine examined shewed any 
tendency to erythristic colouring, though this type is quite 
common in some parts of Spain and is also found in eggs of 
the eastern race from Greece. The average size of thirty- 
nine Corsican eggs is 16*79 x 13*03 mm.; max. 19*1 x 13*7, 
min. 15 X 12*1. A nest found on May 21 contained one egg 
and also one of a Cuckoo. 
71. Sylvia conspicillata conspicillata Temm, Spec¬ 
tacled Warbler. 
Another summer visitor to the fr macchia ” on the hillsides. 
Whitehead found a nest with three eggs and snared the bird on 
May 13. He also saw several others in the vicinity. Giglioli 
describes this species as tolerably common and sedentary, 
but this is probably an error. 
72. Sylvia undata (Bodd.). Furze-Warbler. 
As already pointed out by Hartert and Parrot, Corsican 
birds, on account of their smaller dimensions and dark 
colouring, seem to approach very closely to the North African 
form, S. undata torn Hart., but the examination of further 
material is desirable. Whitehead met with this species in 
two localities in February; Backhouse and Giglioli record 
it from Ajaccio in winter, and the latter also met with it 
in the Golfe de Porto early in October. I found young 
already on the wing and old nests on the east coast on May 11. 
Parrot records specimens from the Ajaccio market ; he 
also obtained one from Solanio, and observed others on 
Finosa at about 1500 ft., in March. It is evidently a local 
resident. 
73. Sylvia sarda Temm. La Marmora's Warbler. 
Sylvia sarda affinis Parrot, Orn. Monatsber. xviii. p. 156

Parrot states that on the average Corsican birds are
