Twenty minutes or so after sunset the clamour becomes suddenly less. It is now possible to discern individual voices. The noise grows rapidly feebler. It almost ceases, but again becomes louder. It then nearly stops a second time. Perhaps not more than twenty voices are heard. There is yet another outburst, but the twitterers are by now very sleepy. Suddenly there is perfect silence for a few seconds, then more feeble twittering, then another silence longer than the last.
It is not yet dark, there is still a bright glow in the western sky. The periods of silence grow more prolonged and the outbursts of twittering become more faint and of shorter duration.
It is now thirty-nine minutes after the sun has set and perfect stillness reigns. The birds must have all fallen asleep. But no! one wakeful fellow commences again. He soon subsides. It has grown so dark that you can no longer see the sparrow-hawk perched on a tree hard by. He took up his position there early in the evening, and will probably breakfast first thing to-morrow morning off sparrow!
You now softly approach the bushes until your face touches the branches. There are twenty or thirty sparrows roosting within fifteen inches of you. You cannot see any of them, but if you were to stretch forth your hand you could as likely as not catch hold of one. You disturb a branch and there is a rustling of a dozen pairs of wings, so close to you that your face is fanned by the wind they cause. You have disturbed some birds, but they are so sleepy that they move without uttering a twitter. You leave the bush and return an hour later. Perfect silence reigns. You may now go right up to the roosting hedge and talk without disturbing any of the three thousand birds. You may even strike a match without arousing one, so soundly do they sleep.
Those who wish to rid a locality of a superabundance of sparrows might well profit by the fact that the birds sleep so soundly in companies. Could anything be easier than to throw a large net over such a hedge and thus secure, at one fell blow, the whole colony?
THE GAY DECEIVER
The drongo cuckoo (Surniculus lugubris) is a bird of which I know practically nothing. I doubt whether I have ever seen it in the flesh. It is, of course, quite unnecessary to apologise for discoursing upon a subject of which one’s knowledge is admittedly nil. In this superficial age the most successful writers are those most ignorant of their subject. When you know only one or two facts it is quite easy to parade them properly, to set them forth to best advantage. They are so few and far between that there is no danger of their jostling one another or bewildering the reader. Then, if you are conversant only with one side of a question, you are able to lay down the law so forcibly, and the public likes having the law laid down for it, it does not mind how crude, how absurd, how impossible one’s sentiments are so long as one is cocksure of them and is not afraid to say so.
My lack of knowledge of the habits of the drongo cuckoo is, however, not my chief reason for desiring to write about it. I wish to discuss the bird because natural selectionists frequently cite it as bearing striking testimony to the truth of their theory, whereas it seems to me that it does just the opposite. Surniculus lugubris is, so far as I am able to judge, an uncompromising opponent of those zoologists who pin their faith to the all-sufficiency of natural selection to account for evolution in the organic world.
The drongo cuckoo is as like the king-crow as one pea is to another. This bird, says Blanford, “is remarkable for its extraordinary resemblance in structure and colourisation to a drongo or king-crow (Dicrurus). The plumage is almost entirely black, and the tail forked owing to the lateral rectrices being turned outwards.” Blanford further declares that the bird, owing to its remarkable likeness to the king-crow, is apt to be overlooked.
This being so, it is quite unnecessary for me to describe the drongo cuckoo; it is the image of a king-crow. But stay, perhaps there are some who do not know this last bird by sight. Such should make its acquaintance. They will find it sitting on the next telegraph wire they pass—a sprightly black bird, much smaller than the crow (with which it has no connection), possessing a long, forked tail. Every now and again it makes little sallies into the air after the “circling gnat,” or anything else insectivorous that presents itself. When you see such a bird you may safely bet on its being a king-crow; the off-chance of its proving a drongo cuckoo may be neglected by all but the ultra-cautious.
