The Himalayan pied kingfisher (_Ceryle lugubris_) is a bird as large as a crow. Its plumage is speckled black and white, like that of a Hamburg fowl. It feeds entirely on fish, and frequents the larger hill streams. Its habit is to squat on a branch, or if the day be cloudy, on a boulder in mid-stream, whence it dives into the water after its quarry. Sometimes, kestrel-like, it hovers in the air on rapidly-vibrating pinions until it espies a fish in the water below, when it closes its wings and drops with a splash in the water, to emerge with a silvery object in its bill. THE UPUPIDAE OR HOOPOE FAMILY The unique hoopoe (_Upupa epops_) next demands our attention. This is a bird about the size of a myna. The wings and tail are boldly marked with alternate bands of black and white. The remainder of the plumage is of a fawn colour. The bill is long and slender, like that of a snipe, but slightly curved. The crest is the feature that distinguishes the hoopoe from all other birds. This opens and closes like a lady's fan. Normally it remains closed, but when the bird is startled, and at the moment when the hoopoe alights on the ground, the crest opens to form a magnificent corona. Hoopoes seek their food on grass-covered land, digging insects out of the earth with their long, pick-like bills. They are very partial to a dust-bath. During the breeding season--that is to say, in April and May in the Himalayas--hoopoes continually utter in low tones _uk-uk-uk_. The call is not unlike that of the coppersmith, but less metallic and much more subdued. The flight of the hoopoe is undulating or jerky, like that of a butterfly. Young hoopoes are reared up in a hole in a building, or in a bank. The nest is incredibly malodoriferous. THE CYPSELIDAE OR SWIFT FAMILY The flight and general appearance of the swifts have already been described. The common Indian swift (_Cypselus affinis_) is perhaps the bird most frequently seen in the Himalayas. A small dark sooty brown bird with a broad white bar across the back, a living monoplane that dashes through the air at the rate of 100 miles an hour, continually giving vent to what Jerdon has so well described as a "shivering scream," can be none other than this species. It nests under the eaves of houses or in verandahs. Hundreds of these swifts nest in the Landour bazar, and there is scarcely a _dak_ bungalow or a deserted building in the whole of Kumaun which does not afford nesting sites for at least a dozen pairs of swifts. About sunset these birds indulge in riotous exercise, dashing with loud screams in and out among the pillars that support the roof of the verandah in which their nests are placed. The nest is composed of mud and feathers and straw. The saliva of the swift is sticky and makes excellent cement.
