           IN FLIGHT
                                                          long legs

        FLIGHT: direct, on broad, strongly arched wings,
        head withdrawn, feet trailing; also higher, or diving
        down from height with aerobatic twists and turns.
           sually moving slowly or standing quite
        U still beside a pool or river, this large, pale
        grey heron is unmistakable. It may, however, look
        tall and slim with a long, erect neck, or round-shouldered and
        hunched with its head and neck withdrawn into the shoulders; it
        may also stand high in a treetop, or fly with surprising agility high
        overhead. It is typically shy, but in towns becomes remarkably bold
        and many now visit garden fish ponds on early-morning raids.
        VOICE Short, harsh fraink; rattling and croaking sounds
        at nest.
        NESTING Large nest of
        thick sticks in treetop (or
        bush where no tree is
        available); 4 or 5 eggs;
        1 brood; January–May.
        FEEDING Catches fish,
        frogs, rats, and other prey
        in its bill, usually after       PERCHING
        long, patient stalk before       The Grey Heron may sometimes be found perched on a treetop, usually
        sudden strike.                   in a hunched posture, with its head and neck drawn into the shoulders.
