182 GARDEN AND AVIARY BIRDS. 



on the other hand, there is no green on the forehead and 

 root of the tail, the head and tail being all grey. Where 

 the two kinds meet they appear to interbreed freely, as 

 any number of intermediate specimens occur ; and as the 

 extreme forms only differ in the points of colour I have 

 mentioned, they can perhaps better be called local varieties 

 than really distinct species. 



These Green Pigeons are sociable birds, being generally 

 seen in flocks ; they feed only on fruit which is small
