The vulgar sparrow and the immaculate canary are members of this large and flourishing family of birds. The distinguishing feature of the finches is a massive beak, admirably adapted to the husking of the grain on which the members of the family feed largely. In some species, as for example the grosbeaks, the bill is immensely thick. Only one species of grosbeak appears to be common in the Himalayas. This is Pycnorhamphus icteroides, the black-and-yellow grosbeak. The colouring of the cock is so like that of the black-headed oriole that it is doubtless frequently mistaken for the latter.
This bird forms the subject of a separate essay, where it is fully described.
The Himalayan greenfinch (Hypacanthis spinoides) is an unobtrusive little bird that loves to sit at the summit of a tree and utter a forlorn peee fifty times a minute. It is a dull green bird with some yellow on the head, neck, and back; the abdomen is of a brighter hue of yellow.
The house-sparrow, like the house-crow, is a bird of the plains rather than of the hills. The common sparrow of the Himalayas is the handsome cinnamon tree-sparrow (Passer cinamomeus). The cock is easily recognised by his bright cinnamon-coloured head and shoulders. Imagine a house-sparrow shorn of sixty per cent. of his impudence, and you will have arrived at a fair estimate of the character of the tree-sparrow.
The only other members of the Finch family that concern us are the buntings. A bunting is a rather superior kind of sparrow—a Lord Curzon among sparrows—a sparrow with a refined beak. The familiar English yellowhammer is a bunting. Two buntings are common in the Western Himalayas. The first of these, the eastern meadow-bunting (Emberiza stracheyi), looks like a large, well-groomed sparrow.
A broad slate-coloured band runs from the base of the beak over the top of the head to the nape of the neck. In addition to this, there are on each side of the head blackish bars, like those on the head of the quail. By these signs the bird may be recognised. The other species is the white-capped bunting (Emberiza stewarti). This is a chestnut-coloured bird with a pale grey cap. Buntings associate in small flocks and affect open rather than well-wooded country. They are not very interesting birds.
A small bird that spends hours together on the wing, dashing through the air at great speed, frequently changing its course, now flying high, now just skimming the ground, must be either a swallow or a swift. Many people are totally at a loss to distinguish between a swallow and a swift. The two birds differ anatomically. A swift is not a passerine bird. It cannot perch. When it wants to take a rest it has to repair to its nest. Swallows, on the other hand, are fond of settling on telegraph wires.
It is quite easy to distinguish between the birds when they are on the wing. A flying swift may be compared to an anchor with enormous flukes (the wings), or to an arrow (the body) attached to a bow (the wings). As the swift dashes through the air at a speed of fully 100 miles an hour, it never closes its wings to the sides of its body; it merely whips the air rapidly with the tips of them. On the other hand, the swallow, when it flies, closes its wings to its body at every stroke. Notwithstanding its greater effort, it does not move nearly so rapidly as the swift. The swifts will be considered in their proper place. Three species of swallow are likely to be seen in the Himalayas. A small ashy brown swallow with a short tail is the crag-martin (Ptyonoprogne rupestris).
The common swallow of England (Hirundo rustica) occurs in large numbers at all hill stations in the Himalayas. This bird should require no description. Its glossy purple-blue plumage, the patches of chestnut red on the forehead and throat, and the elegantly-forked tail must be familiar to every Englishman. As in England, this bird constructs under the eaves of roofs its nest of mud lined with feathers.
Not unlike the common swallow, but readily distinguishable from it in that the lower back is chestnut red, is Hirundo nepalensis—Hodgson’s striated swallow, or the red-rumped swallow, as Jerdon well called it. This bird also breeds under eaves. Numbers of red-rumped swallows are to be seen daily seeking their insect quarry over the lake at Naini Tal.
