CUCKOOS. 3 



16 inches. Its note is described by Canon Tristram as kee-ow, kee-ou, and it has 



an alarm-note resembling the word cark, as well as a third note, like wurree, 



wiirree. It is parasitic, like the members of the genus Cucuhis, but does not 



victimise small birds like the true cuckoos, selecting the nests of crows and 



magpies, whose eggs bear a considerable resemblance to its own. The great spotted 



cuckoo often places two, or even four, of its eggs in a nest ; where the young 



cuckoos often live in peace with the offspring of the foster-parents, and, so far as is 



known, not attempting to eject the rightful owners. The Indian pied crested 



cuckoo (C. jacobinus) lays blue eggs, resembling in colour those of the babbling 



thrushes (Craterojms and Argya), in whose nests it places them. Apparently the 



young cuckoo ejects the rightful owners, when the young are hatched, as the 



babblers are often seen in attendance on their parasitic dependents without any of 



their own young being of the party. Sometimes the cuckoo puts two of its eggs 



into a babbler's nest, and it is said to break some of the foster-parents' eggs to make 



room for its own. Colonel Butler says that when they discover a nest of a babbler, 



Avhich does not suit them to lay in, the cuckoos invariably destroy the eggs already 



there by driving a hole into them with their bills, and sucking the contents.

resemblance ni colour and flight to a sparrow-hawk, being gre}' birds 



with a good deal of rufous below, a large j-ellow eye, and a very broadly banded 



tail. They lay white or greenish - blue eggs, and one species {Hierococcyx 



sparveroides) is said to build its own nest and sit on the eggs. This fact has 



been recorded in the Nilgiri Hills of Southern India, but in the Himalaya the bird 



is stated to be parasitic on the babbling thrushes.

cuckoos by the absence of a crest, the true cuckoos differ from them 



by the shape of the tail, in which the outer feathers are nearly of the same length 

 as the others, instead of decidedly shorter. Moreover, the tail-feathers lack the 

 transverse dark bars of the hawk-cuckoos. The genus is represented by ten 

 species, all very similar to one another, and hawk-like in coloration and appear- 

 ance, the old birds being grey while the young are more or less rufous, the 

 Oriental Sonnerat's cuckoo (Cuculas sonnerati) having, however, the plumage for 

 the most part rufous barred with black. Of the ten species, four are African, one 

 Australian, and the rest Indian. Their notes vary greatly, only one other species 

 besides the European having the " cuckoo " note from which the bird takes its 

 name, this being the South African cuckoo (C. gularis), which has a note similar 

 to that of the common species, but more slowly uttered, and the first s^dlable not 

 in sucli a liigh key. The red-chested cuckoo of Africa (C. solitarius) has a 

 whistling note, on account of which it is known to the colonists at the Cape by the 

 name of Piet - mijn-vrouw, wliile the l)lack cuckoo (C. clamosus) is, as its Latin 

 name implies, a noisy bird, uttering a very loud, harsh note. The Indian cuckoo 

 (C. inicropterus), has a note, which Mr. Oates renders as hho-kusha-khu, while the 

 Asiatic cuckoo (C. inte'miediiis), on the other hand, lias only a single note, a 

 guttural and hollow-sounding hoo, resen»l)ling the cry of the hoopoe. One of the 

 most interesting of all birds is the connnon cuckoo (C. caiiorits), not the least 

 remarkable feature in its conformation l)t'iiig its great similarity to a hawk, as not
