THE CUCKOO. 31 



devote themselves to its support, that they pay no further 

 attention to their own ejected brood, but, allowing them to 

 lie and starve on the ground where they have been thrown 

 by the intruder, they take the most assiduous care of their 

 strange charge, and will even follow it into confinement 

 and feed it. 



This is all the more remarkable because the Cuckoo, 

 probably owing to its resemblance to the hawk, is fre-

Why a bird so bold and fierce in its disposition should 

 be so shiftless and remiss in the discharge of parental

 white. The bill is slightly curved, red on the inside, and 

 in the case of young birds always open. 



The length of the male is about fourteen inches ; the 

 female is a little smaller, but with the exception of being

 this circumstance may possibly explain the fact that the 

 Cuckoo is silent in captivity. In addition to this cry the
