Brotogeris chrysopterus (15-9-21 Naturhistorisches Museum Wien) - ID by Brennan Mulrooney

Description:

Taxidermy specimen at Vienna natural history museum. Signaged as Brotogeris jugularis (orange-chinned parakeet). But when I was about to write my species factsheet I realized that said species should not have a yellow patch in primary coverts: stefaanrommel.files.wordpress.com/2017/09/afbeelding-186.jpgThe specimen also lacks the orange throat typical of Brotogeris jugularis, as well as the bronze tinge on wings.Checked all other Brotogeris species and none matches. B. chiriri have yellow on wings, but in a band occuping the secondary coverts, not the primary.So what I have photographed? A race, a mutation, a non related species, a stained specimen????
