142 How to Sex Cage Birds. 



Southern Fruit-Pigeon (Crocopus chlorogaster). 



The female is slightly the smaller bird ; the differences in the 

 bill are unreliable. " The purple tinge near the bend of the wing 

 very slightly marked, and the under tail-coverts of a grey colour in 

 the middle, more or less mixed with chestnut" (Salvadori, Catalogue 

 of Birds, vol. xxi. p. 30). 



Double-banded Fruit-Pigeon (Osmotreron bicincta). 



The female is perhaps slightly smaller than the male. " Has the 

 blue of the hind neck of less extent, but darker than the male ; the 

 upper surface is more overcast with brownish ; the chest wants the 

 lilac and orange bands ; under tail-coverts whitish, the inner webs 

 mostly cinnamon, and the bases of the feathers dappled with ashy " 

 (Salvadori, Catalogue of Birds, vol. xxi. p. 58). 



Parrot Fruit-Pigeon (Osmotreron vernans). 



" Female differs from the male in having the head, neck, and 

 breast green, with a dull yellowish tinge on the forehead, sides of 

 the head, throat, and breast ; besides, the under tail-coverts are 

 huffish-white, more or less suffused, generally on the inner web, but 

 sometimes on both, with pale dull cinnamon, which, again, is often 

 freckled or powdered in patches with dark grey or greenish-grey ; 

 no grey on the head, no vinous colour round the neck, and no orange 

 patch on the breast" (Salvadori. Catalogue of Birds, vol. xxi. p. 62). 



The species of Ptilopus, on account of their small size, would, I 

 think, be more correct^ spoken of as Doves than as pigeons ; still, 

 they have always been spoken of as pigeons. 



Jambu Fruit-Pigeon (Ptilopus jambu). 



The female is smaller than the male, and the crown of the head 

 is green, suffused with bluish-lavender instead of petunia-crimson; 

 the stripe on the throat dark cinnamon. Breast, greyish-green, its 

 lower portion greyish-white; abdomen white; under tail-coverts of 

 a paler cinnamon than in the male. 



Banded Fruit-Pigeon (Ptilopus fasciatus). 



The female is smaller than the male ; the magenta on the crown 

 without yellow edging at the back ; the back of neck and mantle 

 greyish-green, paler than the back ; under parts also altogether 

 greener than in the male. 



Purple-crowned Fruit Pigeon {Ptilopus j>orphyraceus). 



There seems to be little difference in size between the sexes, but 

 the plumage of the female is altogether much greener than that of 

 the male; apparently the dark green abdominal spot is destitute of 

 a purple tinge, but it is possible that this may prove to be a variable 

 character.
