"This well-known species," writes Jerdon, "is found throughout India, extending to Ceylon, the Burmese countries, and parts of Malayana, to the Philippines. It frequents groves, gardens, avenues, and open jungles; and feeds almost exclusively, I believe, on fruits of various kinds, especially on those of the banian, peepul, and other figs, also, says Blyth, much on that of the _Mimasops elengi_. Several of these birds may be often seen on one tree, but they are not gregarious. Mr. Blyth states that they eject from the mouth the large seeds of any fruit that they have eaten. The Koel is by no means a shy bird, but has the usual quick, unobtrusive habits of the ordinary Cuckoos, as it glides about the branches of trees; when it takes wing, however, it is remarkable for the loudness of its cries. About the breeding season the Koel is very noisy, and may then be heard at all times, even during the night, frequently uttering its well-known cry, of 'Ku-il, ku-il,' increasing in vigour and intensity of utterance as it goes on. The male bird has also another note, which Blyth syllables as 'Ho-whee-ho,' or 'Ho-y-o.' When it takes flight it has yet another somewhat melodious and rich liquid call, all thoroughly _Cuculine_. The female Koel deposits her eggs almost exclusively in the nest of the Common Crow (_Corvus culminatus_). She generally lays only one egg in each nest, and mostly, but not always, destroys the eggs of the proprietor at the time of depositing her own. It is a popular belief that the Crow discovers the imposture when the young Koel is nearly full grown, and ejects it from her abode; but this I do not think is usually if ever the case, for I have frequently seen Crows feeding the young Koels, even after they have left the nest in which she has placed her eggs, and when the birds are fully grown entices them away, or, if expelled, looks after them and feeds them for a few days, but I greatly doubt if this be the general practice." The egg of the Koel is pale olive-green, with numerous reddish, dusky spots, having a tendency to form a zone at the broad end. The Crows would appear to be desirous of avenging the wrongs they receive from these Cuckoos, for at times we see them pursuing the Koel with the utmost energy. Mr. Frith, as quoted by Blyth, states that one dashed itself against a window and was killed when thus hunted by a Crow. The flight of the Koel is not so quiet and gliding as that of the True Cuckoos, but is performed with more numerous strokes with the wing. * * * * *
