I have but two more species to add to this list, 

 namely, the Blackheaded Bunting and Wheatear. 

 In June, 1860, a friend of mine found a nest of the 

 latter bird containing three eggs of the Wheatear 

 and one of the Cuckoo. The nest was placed under 

 a clod, and in such a position as strongly to favour 

 the opinion of some naturalists that the Cuckoo 

 first lays her eggs and then deposits them with her 

 bill in the nest. 



Occasionally an adult Cuckoo is obtained in the 

 reddish-brown plumage peculiar to the young bird, 

 but this happens very rarely. I know of two in- 

 stances in which old birds have been shot in this 

 state of plumage, one having been previously ob- 

 served for three summers, and the other for five 

 or six : they were both females, and I believe an 

 adult male of this colour has never been obtained. 



The adult brown Cuckoo is thought by some to 

 be a distinct species, and has been figured and 

 described under the name of Cuculus hepaticus ;
