116 How to Sex Cage Birds. 



Slight-billed Parrakeet (Henicognathus Uptorhynckus). 

 The beak of the male is generally broader than that of the female, 

 though not at its base ; it is distinctly longer. 



Chilian Conure (Microsittace ferruginea). 

 The male is larger than the female ; its beak is slightly longer, 

 broader, and more curved. 



Red-eared Conure (Pyrrhura cruentata). 

 The male is the larger bird ; its beak is narrower, slightly longer, 

 more arched, not quite so deep at the base when viewed in profile. 



Red-bellied Conure (Pyrrhura vittata). 

 The male is slightly larger than the female; its beak is broader, 

 longer, with more slender terminal hook. 



White-eared Conure (Pyrrhura leucotis). 

 The male is distinctly larger than the female ; its beak is more 

 slender, longer, less arched. 



Blue-winged Conure (Pyrrhura jncta). 

 The male is noticeably larger than Ins mate; its beak is broader 

 at base, longer and more gradually tapered. 



Pearly Conure (Pyrrhura perlata). 

 I could discover no sexed specimens, but, judging by their size, T 

 believe the sexual differences are much the same as m P. leucotis. 



Quaker or Grey-breasted Parrakeet (Myopsittacus monachus). 

 A comparison of the sexed specimens in the Museum led me to the 

 conclusion that the female of this species was much larger than the 

 male and has a considerably longer and more powerful beak. ihese 

 differences do not strike one so much in the living specimens, but 

 the female has a heavier appearance, even in a cage, and it is 

 probable that, when my pair made their way from one aviary to 

 another by clipping out a large circle in the dividing £-ln. wire- 

 netting, most of the work was done by the female. 1 1 requires a 

 very powerful beak to cut netting of this size. It is probable that 

 the hen cuts most of the sticks to form the remarkable nest made by 

 this Parrakeet. 



Lineolated Parrakeet (Bolborhynchus lineolatus). 



The female is smaller than the male, the beak very slightly 



different ; but, judging by the sexed examples in the Museum, the 



pluma-v is not identical as stated, the rump being much less strongly 



spotted with black than the male, and the tail wholly green, the 



feathers not being broadly tipped with black as m the male.
