CUCKOG, COMMON. 
CucuLus canorvs, Lin. 
The Cuckoo arrives in this country about the 
month of April, and the adult bird leaves about 
the beginning of July, but the young birds of the 
year do not leave till about September. The 
Cuckoo is generally distributed over Great Britain 
and the Orkneys during summer. ‘The great pecu- 
larity of this bird appears to be that of depositing 
its solitary ege, for itseldom lays more than one, 
in the nest of some small bird, such as the Hedge 
Sparrow, Pied Wagtail, Linnet, Whitethroat, 
Redstart, Yellow Hammer, and others, but more 
particularly the Hedge Sparrow. When the young 
Cuckoo is hatched it makes an attack upon the 
remaining eges, if any, and offspring of its foster 
parents, destroying the former and generally suc- 
ceeding in turning out the latter. Its back, when 
young, is very broad, with a depression in the 
middle, which disappears in about a fortnight. 
The egg is about the size of Skylark’s, of a light 
mottled reddish grey. 
CUCKOO, GREAT SPOTTED. 
CucuLUs GLANDARIUS, Lin. 
This species inhabits North Africa, and has been 
found also in Germany, Italy, and Spain, but of its 
habits very little is known.
