Birds, as a broad rule, possess no "breeding-plumage." They only renew their dress once a year, in the autumn, and breed the following spring in the worn and ragged plumes. It's not poetic, but the fact.[11] This is not the place to enumerate all the characteristic forms of bird-life, and only one other shall be mentioned, chiefly because the incident occurred the day we drafted this chapter. One hears behind the rustle of strong wings, and there passes overhead in dipping, undulated flight a green woodpecker of the Spanish species, _Gecinus sharpei_. With a regular thud he alights on the rough bark of a cork-oak in front, clings in rigid aplomb while surveying the spot for any sign of danger, then projects upwards a snake-like neck and with vertical beak gives forth a series of maniacal shrieks that resound through the silences.[12] By all means watch and study every phase of wild-life around you--the habit will leave green memories when the keener zest for bigger game shall have dimmed--but never be caught napping, or let a silent stag pass by while your whole attention is concentrated on a tarantula! [Illustration: A TARANTULA] By way of illustrating the practice of "driving," we annex three or four typical instances:-- LAS ANGOSTURAS, _February 5, 1907_.--The writer's post was in a green glade surrounded by pine-forest. A heavy rush behind was succeeded (as anticipated) by the appearance of a big troop of hinds followed by two small staggies. A considerable distance behind these came a single good stag, and already the sights had covered his shoulder, when from the corner of an eye a second, with far finer head, flashed into the picture, going hard, and I decided to change beasts. It was, however, too late. Half automatically, while eyes wandered, fingers had closed on trigger. At the shot the better stag bounded off with great uneven strides through the timber, offering but an uncertain mark. Both animals, however, were recovered. The first, an eleven-pointer, lay dead at the exact spot; the second was brought to bay within 300 yards, a fine royal. LOS NOVARBOS, _January 9, 1903_.--My post was among a grove of pine-saplings in a lovely open plain surrounded by forest. Two good stags trotted past, full broadside, at 80 yards. The first dropped in a heap, as though pole-axed, the second receiving a ball that clearly indicated a kill. While reloading, noticed with surprise that No. 1 had regained his legs and was off at speed. A third bullet struck behind; but it was not till two hours later, after blood-spooring for half a league, that we recovered our game. The first shot had struck a horn (at junction of trez tine) cutting it clean in two. This had momentarily stunned the animal, but the effect had passed off within ten seconds. Both were ten-pointers, with strong black horns, ivory-tipped. During that afternoon I got & big boar at Maë-Corra; and B., who had set out at 4 A.M., twenty-three geese at the Cardo-Inchal.
