Leishra of the Hindoos.
E legant in contour as are the members of the Hirundinidce generally, I question if any Swallow yet
discovered can excel the Hirundo filifera in this respect, neither is there one among them whose aerial
movements are more graceful. None who have studied the various members of this family, and particularly
those of the section to which our own Chimney Swallow (Hirundo rustica) pertains, can have failed to
observe how greatly prolonged are the outer tail-feathers of the males, and that these deeply fork-tailed
birds are characterized also by the elegant proportion of their wings and by a general structure suited for
sustained flight and a variety of aerial evolutions. In some of the species the outer tail-feathers are more
or less broad, while in others they diminish to the thread-like form seen in the present bird.
“ This very beautiful Swallow,” says Mr. Jerdon, “ is found in small numbers throughout India, not in
general ascending mountains to any height, but, according to Adams, occurring rarely in the north-west
Himalayas and Cashmere. It is more rare in the extreme south of India than towards the north, and is
unknown on the Malabar coast, Lower Bengal, and the countries to the eastward. It breeds in old
buildings, on walls, in stone bowries or wells, very commonly under bridges, and in rocks overhanging water,
making a small mud nest open at the top, and laying two or three eggs, which are white, sparingly spotted
with rusty red. I always found the nests single, and we seldom see more than five or six couple in one place.
The Hindustani ñame is given to it from a supposed resemblance of its thin tail-feather to the rod used for
catching birds with bird-lime, which is called Leishra. It is said also to occur in the north-east of Africa.
“ In the northern parts of the country it is very generally spread, and frequents not only the neighbourhood
of water, but also fields, gardens, and open plains. Its long thread-like tail-feathers are only observable
at a few yards’ distance, and in consequence of this, nine-tenths of the Europeans in India are unaware
of its existence. It occasionally perches on trees.”
Colonel Sykes remarks that it is “ very abundant in the Dukhun and very beautiful, with its thread-like
tail-feathers floating behind when in flight.”
With regard to the reported occurrence of this bird in Africa, I may remark that I am inclined
to doubt the identity of the Indian and African birds; for fine examples of both now before me appear to
differ too much to admit of their being considered as examples of one and the same species. The Gambian
specimens are much smaller, have a lesser amount of rufous colouring on the head, and shorter tails.
As is the case with the Swallows in general, the sexes are alike in colour, but the female is of smaller
size and has the outer tail-feathers much shorter than those of the male.
Crown of the head rich rusty red; lores black; upper surface, wings, and tail glossy steel-blue; throat
and under surface generally pure white; all but the four central tail-feathers with a nearly square spot of
white on the inner web near the tip; irides, bill, and feet black.
The figures are of the natural size.
