P.e. fleurieuensis: both adults different from elegans by having deep orange/red plumage; grey/black mantle and back, spotted with dull orange/red; outer median and outer secondary wing coverts pale blue. P.e. subadelaidae: both adults orange/red forehead, crown and face, turning to brighter red on frontal band; dull yellow underparts, often washed dull orange/red; grey/black mantle and back spotted dull yellow; olive/yellow lower back to upper tail coverts. P.e. flaveolus: both adults bright pale yellow in colour; orange/red lores and frontal band; black mantle and back spotted yellow; olive/yellow rump and upper tail coverts.

Colourization Juvenile:
P.e. elegans: bright olive/green in colour; red forehead, crown and borders to cheek patches, throat, upper breast, thighs and undertail coverts; dark olive/green tail; white underwing stripe. P.e. nigrescens: as in adults but duller, darker red on head, rump and underparts; faint scalloping with black on feathers of breast; black mantle and back with red spotting and suffused with dull olive/green. P.e. melanopterus: as in elegans. P.e. fleurieuensis: as in elegans, but in general duller green and less olive; orange/red markings replacing red marks. P.e. subadelaidae: as in fleurieuensis but paler green with more yellow in plumage; frontal band bright orange/red; purple/blue cheek patches bordered with dull orange/red; orange/red crown; dull orange/yellow throat, upper breast, thighs and undertail coverts washed with dull orange/red. P.e. flaveolus: frontal band narrow and pale orange/red; olive/green upperparts with minimal spotting on back and mantle, becoming dull yellow/olive on rump and upper tail coverts; dull olive/yellow underparts; white underwing stripe. P.e. fleurieuensis X e. subadelaidae X e. flaveolus: in general dull olive/green; forehead, crown, throat, upper breast, thighs and under tail coverts in varying hues from orange/yellow to dull orange/red; yellow/olive rump and upper tail coverts; olive/green tail.
