1921.] Birds of Alcudia, Majorca. 
12. Spinus spinus. Siskin. 
Common during the winter in considerable flocks, but 
apparently none remain to breed. 
Von Jordans quotes Barcelo in his list. 
13. Spinus citrinella. Citril Finch. 
Von Jordans includes this species 011 the authority of 
Barcelo. 
14. Serinus serinus. Serin. 
A common species throughout the year, assembling in 
flocks in the winter. They resort to the pine-woods and 
orchards for nesting early in April, and I found a nest con¬ 
taining tiny young ones on 26 April, 1920, and on the same 
day another nest which the birds were building. The nest 
is usually placed in the first fork of a small pine, and is a 
most beautiful little structure of twigs and moss, thickly 
lined with feathers. 
Obtained by v. Jordans. 
15. Passer domesticus. House-Sparrow. 
A common resident, but at present not very abundant, 
though, owing to increased cultivation, it is annually becom¬ 
ing more plentiful. A good many nest in the rocky sides of 
a ruined subterranean chapel out in the open country near 
Alcudia, at some distance from dwellings. 
Obtained by v. Jordans. Witherby found many breeding 
in a cliff near Lluch. 
16. Passer italise. Italian Sparrow. 
Included in v. Jordans’ list on the authority of Homeyer, 
but its occurrence is very doubtful. 
17. Passer montanus. Tree-Sparrow. 
Von Jordans includes this species on the authority of 
Barcelo and others, but I have never yet observed it. 
1<S. Fringilla ccelebs. Chaffinch. 
Extremely plentiful all the year. Numbers nest in the 
pine-woods, in the orchards, and, less plentifully, among the 
hills. They commence building early in April. The song 
is harsh and feeble.
