Is New Guinea's "Mountain Robin" (Petroica bivittata) Dimorphic? (1 Viewer)

Hello there!,

Unfortunately I don't have easy access to, say, the BirdLife International Illustrated Checklist of the Birds of the World. Thus, posting here seems to be a logical avenue...

After scouring the internet for hours upon hours (and hours), it appears very little is known about this species (Petroica bivittata).

Anyway, my question is this:

Is Petroica bivittata sexually dimorphic, -and if so then to what degree? (That is, would it take a professional birder to spot the differences quickly, or is it more obvious like the female is brown rather than black/white, for example?)​


Perhaps someone here has resources on the bird that I don't, -and any sharing of knowledge would be greatly appreciated. (!!!)

Thank you kindly!
