Ornithology of Corsica . 
P. domesticus it nests in trees as well as in buildings and 
often several big, untidy nests may be seen high up in the 
olive-trees close to the towns. The holes left for scaffolding 
in houses are also frequently occupied. The breeding-season 
is rather late : the earliest date I have for a full clutch is 
May 9, but few eggs are laid before the middle of the month 
and most in the latter part of May and early in June, while 
the clutch generally consists of 5 or 6 eggs. 
[Passer hispaniolensis arrigonii Tsch. (Ornith. Jahrbuch, 
xiv. p. 8), described from Sardinia, may possibly occur in 
Corsica also, but at present there seems to be no evidence 
to that effect.] 
25. Passer montanus (L.). 
A series of five specimens was collected for Dr. Parrot 
from the neighbourhood of Ajaccio in mid-May, and 
Dr. Schiebel also recognised it. None of the other observers 
appears to have noticed it. Wings 66*5-69 mm. (4 males), 
63*5 (1 female).

Corn-Bunting.

Both Wharton and Whitehead describe the Corn-Bunting 
as a fairly common resident, but Parrot noticed none near 
Ajaccio till March 1, and regards it as a migrant. It is 
probably resident in the low-lying parts of the island, but is 
not found in the mountains, and is subject to local move¬ 
ments during the winter. It is apparently commonest on 
the Campo de L’Oro, but also breeds sparingly along the 
east side of the island. Parrot distinguishes it on account 
of the darker ground-colour of the mantle and more distinct 
markings, but I have not been able to examine specimens. 
The eggs are laid in the latter half of May, and are 5-6 
in number; 11 Corsican examples average only 23*57x 
16*61 mm. in size; max. 24*3x17*1, min. 23x16*5 and 
24x 16*1.
