The green-backed tit is one of the most abundant birds in the Himalayas. It is about the size of a sparrow. The head is black with a small perky crest. The cheeks are spotless white. The back of the head is connected by a narrow black collar with an expansive shirtfront of this hue. The remainder of the plumage is bright yellow. The back is greenish yellow, the rest of the plumage is slaty with some dashes of black and white. Thus the green-backed tit is a smart little bird. It is as vivacious as it is smart. It constantly utters a sharp, not unpleasant, metallic dissyllabic call, which sounds like kiss me, kiss me, kiss me, kiss me. This is one of the most familiar of the tunes that enliven our northern hill stations.
So much for the bird: now for its nest. A nest in a hole possesses many advantages. Its preparation does not entail very much labour. It has not to be built; it merely needs furnishing, and this does not occupy long if the occupiers have Spartan tastes. The tits in question were luxuriously inclined, if we may judge by the amount of moss that they carried into that hole. By the time it was finished it must have been considerably softer than the bed that was provided for my accommodation!
Moss in plenty was to be had for the taking; the trunks and larger branches of the trees which surrounded the "hotel" were covered with soft green moss. The tits experienced no difficulty in ripping this off with the beak.
The entrance to the nest hole faced downwards and was guarded on one side by the wall of the house, and on the other by a beam, so that it was not altogether easy of access even to a bird. Consequently a good deal of the moss gathered by the tits did not reach its destination; they let it fall while they were negotiating the entrance.
When a piece of moss dropped from the bird's beak, no attempt was made to retrieve it, although it only fell some 10 feet on to the floor of the verandah. In this respect all birds behave alike. They never attempt to reclaim that which they have let fall. A bird will spend the greater part of half an hour in wrenching a twig from a tree: yet, if this is dropped while being carried to the nest, the bird seems to lose all further interest in it.
By the end of the first day's work at the nest, the pair of tits had left quite a respectable collection of moss on the floor. This was swept away next morning. On the second day much less was dropped; practice had taught the tits how best to enter the nest hole.
It will be noticed that I speak of "tits." I believe I am correct in so doing; I think that both cock and hen work at the nest. I cannot say for certain, for I am not able to distinguish a lady- from a gentleman-tit. I never saw them together at the nest, but I noticed that the bird bringing material to it sometimes flew direct from a tree and at others alighted on the projecting end of a roof beam which the carpenters had been too lazy to saw off. It is my belief that the bird that used to alight on the beam was not the same as the one that flew direct from the tree. Birds are creatures of habit. If you observe a mother bird feeding her young, you will notice that she, when not disturbed, almost invariably approaches the nest in a certain fixed manner. She will perch, time after time, on one particular branch near the nest, and thence fly to her open-mouthed brood. When both parents bring food to the nest, each approaches in a way peculiar to itself; the hen will perhaps always come in from the left and the cock from the right.
The tits in question worked spasmodically at the nest throughout the hours of daylight. For ten minutes or so they would bring in piece after piece of moss at a great pace and then indulge in a little relaxation. All work and no play makes a tit a dull bird.
I had to leave the hotel late on the second day, so was not able to follow up the fortunes of the two little birds. I have, however, to thank them for affording me some amusement and giving me pleasant recollections of the place. It was good to lounge in a long chair, drink in the cool air, and watch the little birds at work. I shall soon forget the tumble-down appearance of the house, its seedy furniture, its coarse durries, and its hard beds, but shall long remember the great snow-capped peaks in the distance, the green moss-clad trees near about, the birds that sang in these, the sunbeams that played among the leaves, and, above all, the two little tits that worked so industriously at their nest.
