Big Heron (L 75 cm), this elusive bird is heard much more often than it is seen. The Bittern is most often found in marshes dominated by reeds and bulrush. The diet consists mainly of fish, amphibians and invertebrates. Birds and small mammals are also eaten occasionally. Migrant.
Reasons for the need for protection/inclusion in annex I
Breeding numbers have declined recently in most European countries, attributed to decrease in habitat quality and availability. Much of the marshes has been lost to drainage, but the abandonnement of traditional management and uses of reed areas has also caused degradation of suitable sites. Local extinctions of the species is probably due to hunting pressure.
