Ornithologij of Corsica. 205 



P. domesticus it nests in trees as well as in buildings and 

 often several big, imtidy nests may be seen liigli up in the 

 olive-trees close to tLe 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 Mspaniolensis 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*3xl7"], min. 23xl6'5 and 

 24x16-1.
