On the Ornithology of Corsica. 
April (cf. Dresser, ‘ Birds of Europe/ ii. p. 365). In the 
thickets near Ghisonaccia and Aleria this bird is extremely 
plentiful, and the chorus of melody about 4.30 a.m. towards 
the end of May is something never to be forgotten. Many of 
the nests are placed 3 ft. or more from the ground in bramble 
thickets, and full clutches may be found from May 14 on¬ 
wards. Average size of 26 Corsican eggs, 20*82 X 16*02 mm.; 
max. 22-9 x 17, min. 19*5 x 15*7 and 20*1 x 15*3. 
88. Luscinia suecica cyanecula (Wolf). W^hite-spotted 
Bluethroat. 
Only three records on spring migration : one shot by Jesse 
on April 12 at Biguglia, another killed by Whitehead on 
March 28, and an old male obtained by Parrot on March 28 
on the Isles Sanguinaires. 
89. Dandalus rubecula sardus (Kleinsclim.). Sardinian 
Redbreast. 
Erithacus dandalus sardus Kleinschmidt, Falco, ii. p. 71 
(1906—Sardinia). 
Local name : Pettirosso. Distinguished from the Conti¬ 
nental Redbreast by the darker and more olive tone of the 
upper surface and the deeper red-brown of the throat and 
upper breast, in this respect approaching our British insular 
form, D. rubecula melophilus. Parrot noticed considerable 
variation in winter-killed specimens, among which probably 
both D. r. sardus and D. r. rubecula were represented. 
During the winter Redbreasts are very abundant in the plain, 
and great numbers are killed for the market. Most of these 
disappear as spring advances, but even in the plage an occa¬ 
sional pair may be found breeding in the densest macchia. 
They are, however, decidedly rare, but in the mountain 
forests at 2000-3000 ft. and upwards they are quite common, 
especially among the pine-woods.
