Feathered raptores, such as eagles, kites, and buzzards, can also be obtained by "calling," but, as above indicated, their loftier position enables them to see the guns, and it is necessary in their case to prepare a covered shelter in which one can stand, concealed from above. 4. WATCHING.--The fourth and last system brings one face to face with wild nature in her nocturnal aspects. Such aspects (to the majority of mankind) are unknown; but night-work, whether at home, in Africa, or in Spain, has always strongly appealed to the writers. Wild creatures do not go to bed at night like lazy men; on the contrary, night is the period of fullest activity for a large proportion of God's creation, whether of fur or feather. To form an intimate personal acquaintance (however imperfect) with these, the comfort of the blankets must be sacrificed. Where stretches of open country border or intersect jungle, or lie between the nocturnal hunting-grounds of carnivorae and the thickets where they lie-up by day, there one may enjoy hours of intense interest in watching what passes under the moon. In the Coto Doñana we have many such spots, some within an hour or two's ride of our shooting-lodges. Here, when the moon shines full, and the soft south wind blows towards the dark leagues of cistus and tree-heath behind us, we line-out three or four guns, each looking outwards across glittering sand-wastes on his front. There, on smooth expanse, one may detect every moving thing. Those shadowy forms that seem to skim the surface without touching it are stone-curlews, and beyond them is a less mobile object, whose identity none would guess by sight. That is a _tortuga_, or land-tortoise, tracing its singular double trail. Across the sand passes a bigger shadow--rabbits and the rest all vanish. What was that shadow? A strange growl overhead, and you see it is an eagle-owl that has scattered the ghost-like groups. Now there is something on the far skyline ahead--something that moves and puzzles--four mobile objects that were not there five seconds ago. These prove to be the ears of two hinds; presently the spiky horns of a stag appear behind them, and the trio move slowly across our front, stopping to nibble some tuft of bent.
