THIS is one of the birds commonly selected as an illustration of “protective coloration.” It lives in the sandy deserts, and its plumage displays a curiously harmonious blending of the various colours to be found on the dry, stony, sandy soil. The very markedly contrasting colours of the head are just the very same that you see in the pebbles or stones, and the smoother passages of delicate buff and greyish-yellow are the counterpart of the curving slopes of pure sand; whilst even the startling enamel-like white of the legs resembles the bleached, hard, dry stalks of the desert vegetation. When the bird crouches down it is practically invisible, though, as the phrase is, it may be “right under your nose,” but as a matter of fact it seems most often to perversely upset the whole value of what we men deem its valuable
protective asset by running about, and drawing attention to itself by continually uttering its peculiar cry. And when it rises and flies off, as it frequently does, in little bands or parties, all utter the same note with incessant, noisy reiteration. I first saw this bird when riding across the desert towards Kosseir on the Red Sea, and I well remember my surprise at seeing how completely different was the position assumed by the birds to that which all the pictures with which I was familiar had led me to expect. It runs about very high on the legs, and every other moment lifts its body up nearly perpendicularly, looking sharply round right and left before again making another quick little run in search of some speck of food. It struck me as being a peculiarly cheery little bird, and seemed to be of a sociable nature, always being in little parties, and often when they all rose together they would be quickly joined by some others, who had been before out of sight, and together they would go wheeling about in mid-air, mounting high up into the sky, till the eye unaided lost sight of them, but all the time their whereabouts was certain, because of their most musical, reiterated cry, which somewhat resembles that of the Sand Grouse.
It loves the deserts, and as far as I know never leaves them save to come down, as the Sand-grouse do, to some water-hole. Round the Pyramids, and even within sight of the babel of guides and donkey boys, this child of the desert may be seen, but it always keeps, as it were, in touch with the boundless open sandy tracts to which it can beat a safe retreat. In one of the large show-cases in the great Central Hall of the British Museum of Natural History, they are shown in a group with other desert birds and beasts, but it is sad to see how the colours of their plumage get—even with all the care of dust-proof cases—dull, faded and dingy, giving little idea of the brilliantly clear, delicately coloured plumage of the living bird, as seen under the clear blue of an Egyptian sky.
