Genus ARDBTTA Gray. 



17. Ardetta bryani,* spec. nov. Kakak. Bittern. 



This little bittern is found in abundance along the streams and 

 in the reed}' marshes ; taro patches and rice paddies are also its 

 favorite feeding grounds. The native name of Kakak is a very 

 good imitation of the cry it makes as it flys up when disturbed. 

 The coloring of this bird blends so well with its surroundings that 

 it takes ver}' careful observation to see them, of which fact the birds 

 seem well aware and remain perfedtlj^ still until they are almost 

 stepped upon, when they fl}- up, calling out a loud "kaka-kakak". 

 Their food is chiefly insects and their larv^ae. Some of the speci- 

 mens examined had their stomachs filled with black crickets. 

 Eight specimens were secured, two adult males, two adult females, 

 and four immature: —
