             IN FLIGHT

                                                                     ADULT
        FLIGHT: prolonged, expert soaring and gliding
        with very occasional deep, ponderous wingbeat;
        flaps heavily in cold, still air.
           ne of the world’s largest
        Oflying birds, the Black Vulture’s
        massive bulk and majestic soaring and
        gliding flight give it terrific impact
        whenever it is aloft. It exhibits great skill at
        utilizing every updraught or breath of wind to soar
        effortlessly without wingbeats. Its flat-winged flight
        gives the Black Vulture a very broad, rectangular shape,
        which is less elegant and shapely than a Griffon
        Vulture’s. Unlike the Griffon Vulture, it nests and often
        perches in trees (rather than on cliffs), and also spends
        much time on the ground, especially near food such as
        a sheep or goat carcass.
        VOICE Mostly silent.
        NESTING Huge stick nest in flat-topped trees; 1 egg,
        1 brood;April–June.               GIANTS OF THE AIR
        FEEDING Rarely catches live prey; mostly eats  A very impressive bird, the Black Vulture has great presence in the sky, even
        carrion; also feeds at special feeding stations.  among equally large Griffon Vultures; its pale head and feet may be obvious.
