RED-CAPPED PARROT PURPUREICEPHALUS-SPURIUS - MOLT, AGE AND SEX DETERMINATION

Descriptions of the plumage and soft parts, the timing and duration of moult and some morphometrics of wild-caught and captive Red-capped Pa rrots Purpureicephalus spurius were recorded so that age and sex could be determined. Plumage characteristics of adults and immatures were v ery different while those of males and females within age classes were very similar. Presence or absence of a wing-stripe allowed some, but not all, birds within age classes to be sexed. The sequence of flight feather moult was clearly defined and the period of body moult continu ed throughout the year in all age classes.
