GREAT SPOTTED CUCKOO. 
Cuculus glandarius, Lznn. 
Le Coucou Geai ou, Tacheté. 
Tue crested head, lengthened and powerful tarsi, together with the more elegant form exhibited in the bird 
before us, indicate very clearly that a further subdivision of the family is requisite: the reason why we have 
figured it under the generic name of Cuculus, and not under that of Coccyzus, applied to it by some authors, is 
that the bird to which the latter title was first applied possesses characters different from either the present 
bird or the true Cuckoos. 
We do not in this place feel disposed to enter largely into a consideration of the divisions of this family, 
and therefore defer adding a new generic name to the Great Spotted Cuckoo until we have had an opportu- 
nity, which we hope will occur at no distant period, of revising the whole group, when not only this, but 
several other species will be brought under investigation. 
So little is known of the habits and manners of this bird that it is still uncertain whether, like the species 
common to England, its eggs and offspring are confided to the care of other birds, or whether it constructs 
its own nest and performs the process of incubation in the ordinary way ; which paucity of information is 
occasioned by its being so sparingly dispersed over the continent of Europe that no opportunities have 
occurred of observing the most interesting portion of its economy,—its nidification. 
Its true habitat is the wooded districts skirting the sultry plains of North Africa ; but the few that pass the 
Mediterranean find a congenial climate in Spain and Italy, further north than which they are rarely seen. 
That valuable work the ‘‘ Planches Coloriées” of M. Temminck contains an accurate description of this 
bird in all its various changes of plumage, a portion of which we venture to extract. This Cuckoo, which is 
larger than the common species, is characterized by a crest comprised of filamentous feathers, by a very long 
graduated tail, by the linear and tubular form of the nostrils, and by the comparatively strong bill and feet. 
In the old male the crest, all the head, and the cheeks are ash colour, more or less deep according to age ; 
the stems of the feathers of these parts are brown, and the base of the webs whitish; a band of blackish ash 
commences at the regions of the ears, passes under the occiput, and extends to the nape of the neck ; the 
back, the rump, the scapularies, and the coverts of the wings are of a greyish brown tint, slightly clouded 
with a greenish lustre, the tips of all these feathers having a white spot, which varies in size and purity ac- 
cording to age; the young and birds of the middle age have these spots more extended and better defined 
than the adults and old birds; the primaries are of a dark brown, edged with grey, and terminated with 
white ; the feathers of the tail are ash brown ending in pure white; throat and chest reddish white; the 
abdomen and under tail-coverts pure white; the feet are dark brown inclining to yellow on the under 
surface ; the bill is brownish black at the point; the base of the under mandible reddish yellow. 
The plumage of the middle age differs from that of the adult in having the head and crest of a much 
darker colour and the whole of the upper surface more inclining to reddish brown with slight reflexions of 
green; the primaries are rufous, tinged with greenish brown towards the points, which are pure white; the 
throat and chest are clear reddish brown; the under surface as in the adult male. 
The young of the year is still darker in its plumage; the crest is short; the feathers of the back and 
secondaries are of a reddish brown; the two middle tail-feathers are slightly tipped with white; the front 
of the neck and the chest are deep rufous; all the other inferior parts are reddish white; feet and beak 
lead colour ; irides grey. 
The Plate represents a male of the natural size, nearly adult.
