Remark: The collection site on the label, underside and in Schlegel 1867 differ. The label, tag, underside, and Schlegel 1867 all identify the specimen as female, but only the latter identifies it as an adult. Its origin could be traced from one of the acquisition books in MNHN, that clearly shows the exchange of this bird to Temminck in April 1825.
