BIRDS FOUND IN BAYOUS AND MARSHES 91 



may be most frequently heard. They are solitary birds, 

 each pair nesting alone. Their food consists largely of 

 frogs and small fish, which they obtain by still fishing, 

 standing motionless for almost any length of time in 

 shallow water among rushes. 



The newly hatched Bitterns are particularly homely 

 nestlings, with their disproportionately long necks and 

 bills. They are fed by regurgitation for at least forty- 

 eight hours after hatching. The Bittern's attempts at 

 love-making and brooding are rendered pitifully grotesque 

 by the ungainly body of the bird and his queer contor- 

 tions. Even in flight he is slovenly and loose-jointed, as 

 if his legs were likely to be shaken off from the eSbrts 

 his wings are making. In fishing he sits motionless 

 for hours with head drawn back to the shoulders, the 

 very picture of discomfort. In fact, under no circum- 

 stances does he seem joyous or even moderately happy.
