ARDEIDA: HERONS AND BITTERNS 
Large birds, slow and stealthy in movement, they either stand mo- 
tionless with their head drawn in between their shoulders, or with 
long, careful steps move along the shore watching for their food of 
fish and reptiles. They feed in meadows and marshes and on the 
edges of ponds and rivers. In flight they are noticeable by their 
large size and dark plumage, their large, round wings, short tails 
and outstretched legs.
