Two in One Nest. 97 



" In the chapter on the cuckoo in Our Summer 

 Migrants, it is remarked (p. 230) that two cuckoos' 

 eggs of a different colour have been found in the 

 same nest. If both were laid by one bird, then we 

 have proof that the same cuckoo does not always lay 

 eggs of the same colour ; if laid by different birds, 

 then the cuckoo is not so impressionable as has been 

 supposed. The full bearing of these remarks will be 

 better understood by referring to the context, which 

 is too long to be here quoted." '■'■'
