Amazons, Etc. 119 



Guilding's Amazon (Chrysotis guildingi). 



The beak of the male is much narrower than that of the female, 

 the culmen more arched. 



August Amazon {Chrysotis augusta). 



According to Count Salvadori, the female is "perhaps a little 

 duller " than the male ; in the Museum series I only found the 

 female sexed ; the beak, however, probably differs as in the pre- 

 ceding species. 



Yinacbous Amazon (Chrysotis vinacea). 



The male is larger than the female ; her beak is broader, but 

 more compressed from the nostrils outwards on each side of the 

 culmen ; the latter is also more arched.* 



Blue-faced Amazon (Chrysotis versicolor). 



I only found females sexed, but in wild examples the differences 

 would probably be characteristic of the genus, the male with longer 

 beak. Oddly enough, the two sexed examples in the Museum, 

 though both labelled as females, look much like opposite sexes. 

 Can captivity have modified the normal character of the beak, or is 

 the cage-bird wrongly sexed 1 



Guatemalan Amazon (Chrysotis guatemalce). 



In this species the male has a narrower beak, especially at the 

 base, than the female, and the terminal hook is more slender. 



Mealy Amazon (Chrysotis farinosa). 



The beak of the male is slightly narrower at the base, shorter, 

 and with broader terminal hook than that of the female ; the sexed 

 males in the Museum have a large patch of yellow and red on the 

 crown, the sexed females barely a trace of yellow and no red, yet 

 Count Salvadori seems to think that the few yellow feathers on the 

 crown indicate younger birds. I can only say that, if this is the 

 case, the female specimens show no other indications of youth. 



Mercenary Amazon (Chrysotis mercenaria). 

 I only found sexed females, but the males probably differ as in 

 the preceding species. 



Orange-winged Amazon (Chrysotis amazonica). 



The beak of the male is longer, more tapering, and less arched 

 than that of the female. 



Blue-fronted Amazon (Chrysotis cestiva). 



The beak of the male is longer and narrower at the base than 

 that of the female. 



* Female a little duller, bill less bright red. — Wicd.
