2. CUCULUS ToLut 



Kradok, or Booboot. <^fj. o J \fi 



The colours of this bird vary considerably at different ages. 

 When young it is of a greenish- black, with rufous wings. As 

 it becomes older, the belly becomes whiter, the shafts of the 

 feathers on the head and back acquire a light colour, and the 

 upper feathers of the tail become barred with grey. It lives on 

 insects, is chiefly observed on the ground, and has a weak 

 flight.
