The eggs vary somewhat, some clutches being more heavily 
marked than others, but, as a rule, they are handsomely 
spotted and blotched with rich red-brown at the big end. 
Average size of forty-two eggs (14 collected by Whitehead 
and 28 by the writer), 17T8 x 12 96 mm.; max. 18*5 x 13*3 
and 18x13*5, min. 16x12*5 and 16*5 x 12*1. Average 
weight of 17 eggs, 82*2 mg. 
Tiie text-figures (pp. 444, 445) will give some idea of the 
usual breeding-places of this species. Text-fig. 11 (drawn 
from a photograph taken by Mr. R. II. Read) represents 
the ascent of a dead pine which contained a nest in an old 
Woodpecker’s hole, about 40 ft. from the ground. Text- 
fig. 12 illustrates a nest-hole picked out in a pine by the 
Nuthatchs, which was only about 18 ft. up; the pine was 
badly cracked a foot or two above the nest. 
45. Parus major corsus Kleinschm. Corsican Great Tit. 
Parus corsus Ivleinschmidt, Ornith. Monatsber. xi. p. 6 
(1903—Corsica). 
Local name : Capinera. Differs from the ordinary con¬ 
tinental form in its slightly smaller size and shorter wing- 
measurement, while the white spot on the inner web of the 
outer tail-feathers is much smaller and sometimes almost 
absent. An extremely common and widely distributed 
resident, breeding in the holes of the cork-oaks on the low 
ground and also in fair numbers in the mountain forests. 
The eggs, seven to nine in number, may be found in the latter 
half of May. Average size of 48 eggs, 17*98 x 13*72 mm. ; 
max. 19*3x13*2 and 17*3x14*5, min. 17x13*3 and 17*2x 
13*2. Some clutches are very boldly marked. 
46. Parus mERULEus ogltastras Hart. Corsican Blue Tit. 
Parus cceruleus ogliastrce Hartert, Vogel pal. Fauna, i. 
p. 349 (1905—Sardinia and Corsica). 
Local name : Sturzapridi (Giglioli). A darker race than 
the ordinary continental form, in this respect closely re¬ 
sembling the British Blue Tit, and shorter winged than 
P. cceruleus cceruleus. Though a common resident, it is 
not nearly so plentiful as P. major corsus, but is equally
