150 How to Sex Cage Birds. 



Vinaceous Turtle Dove (Turtv/r vinaceus). 



Only one male is sexed in the Museum, but in picking out a 

 female I should look for the same differences indicated for the 

 preceding three species. 



Ruddy Turtle Dove (Turtur humilis). 



"Female. — General colour pale brown, but the lower parts vinous- 

 grey where vinous-red in the male. There is a black collar as in 

 the male, but edged above with whitish-grey " (Salvadori, Catalogue 

 of Birds, vol. xxi. p. 435). 



Chinese Turtle Dove [Turtur chinensis). 



The sexes are much alike, but the female is slightly smaller and 

 less alert in appearance. 



Necklaced Dove (Turtur tigrinus). 

 The same note applies to this as to the preceding species. 



Spotted Turtle Dove (Turtur suratensis). 



The female is a trifle smaller than the male, and less alert in 

 appearance, as in the two preceding allied species. 



Senegal Turtle Dove (Turtur senegalensis). 



Also known as the Cambayan Turtle Dove. The female is 

 smaller and duller in colouring than the male. 



Aberrant Turtle Doves (Geopeliince). 

 Bar-shouldered Dove (Geopelia humeralis). 



The female is slightly smaller than the male (but, unfortunately, 

 the males also vary a good deal in size) ; her breast, however, is of a 

 darker and duller grey than in the male. 



Peaceful Dove (Geopelia tranquilla). 



The female is a smaller, less slender, and alert bird than the male, 

 but the sexes are extremely alike in the skin. 



Zebra Dove (Geopelia striata). 



The female is smaller than the male, and shows less reddish 

 tinting on the crown. 



Mauge's Dove (Geopelia maugcei). 

 The female is smaller and less slender in appearance than 

 the male. 



Diamond Dove (Geopelia cuneata). 



" Femah. — Smaller than the male ; back of the head, neck, 

 and upper surface browner, and the spots on the wings larger" 

 (Salvadori, Catalogue of Birds, vol. xxi. p. 463).
