          IN FLIGHT

                      MALE
                      (WINTER)
          his is a common diving duck, swimming
        Tand feeding in flocks, with individuals disappearing
        under in search of food. Males are strongly contrasted except   FLIGHT: fast but not manouevrable; flocks make
        in mid-summer, while females are dark and dull. Flocks are   tight, irregular packs.
        often mixed with Pochards and are worth scanning
        through for individuals of rarer species that are
        naturally attracted to their company.Tufted Ducks are
        sometimes semi-tame and come for food on ponds in
        town parks. Even flocks on lakes and reservoirs often
        tolerate a quite close approach, or simply swim away
        from disturbance.
        VOICE Deep, grating growl; male calls with nasal
        whistles during courtship.
        NESTING Down-lined hollow in long vegetation
        close to water; 8–11 eggs; 1 brood; May–June.  WINTER FLOCK
        FEEDING Dives underwater from surface to find  Tufted Ducks, with Pochards, form quiet, sleepy flocks on inland waters;
        molluscs and insects.            these flocks are sometimes quite large.
