The natives assert that the hen koel keeps an eye on her offspring all the while they are in the crow’s nest and takes charge of them after they leave it. I am almost certain that this is not so.
Early in April the paradise flycatchers (_Terpsiphone paradisi_) arrive. The hen is a chestnut bird with a black head and crest and a white breast; she looks something like a bulbul. The cock when quite young is similarly attired. At his first autumnal moult, that is to say when he is about fifteen months old, his two middle tail feathers outgrow the rest by twelve or thirteen inches. In his third year white feathers begin to appear among the chestnut ones, and after his third autumnal moult he emerges as a magnificent white bird with a metallic black head and crest. His elongated tail feathers now look like white satin streamers. He retains this livery for the remainder of his life, and looks so magnificent in it as to merit well his name. It is impossible to mistake the paradise flycatcher. There is no other bird like it. It is a denizen of orchards and shady groves and may always be seen during the hot weather in the beautiful wood on the bank of the Ravi between the bridge of boats and the railway. A cock paradise flycatcher, in the full glory of his white plumage, as he flits like a sprite through the leafy glade, is a sight never to be forgotten. The movements of his long tail feathers as he pursues his course are as graceful as those of the folds of the gossamer garments of a skilled serpentine dancer.
The nest is a deep cup, in shape like an inverted cone, plastered exteriorly with cobweb and white cocoons. It is almost invariably placed in a fork near the end of one of the lower branches of a tree. Both cock and hen take part in nest building and incubation. As the cock sits his long white tail feathers hang down over the side of the nest and render him very conspicuous. The most expeditious way of finding a paradise flycatcher’s nest is to look out for a sitting cock. The alarm note of this species is a sharp harsh _Tschit_, but the cock is also able to warble a very sweet song.
The Indian oriole (_Oriolus kundoo_) is another gorgeous summer visitor to the Punjab. The cock is arrayed in rich golden yellow. His bill is pink and he has a black patch on each side of his head, there is also some black in his wings and tail. The hen is clad in greenish yellow and is neither so showy nor so handsome. The oriole is commonly called the mango bird by Europeans in India. I have never been able to discover whether the bird is so named because the cock is not unlike a ripe mango in colour, or because orioles are to be found in almost every mango tope. _Oriolus kundoo_ is a bird of many notes. Of these the most pleasing is a mellow _lorio, lorio_. Another note very frequently heard is a loud but not unmusical _tew_. The alarm note of the species is a plaintive cry, not easy to describe. It is uttered whenever a human being approaches the nest. The hen alone incubates, but she is not often seen upon the nest, for she leaves it at the first sound of a human footfall.
