Hi
From the NSW Bird Atlassers Atlas of the Birds of NSW.
There was no reference to the "reported interbreeding" .
Cheers Chris
Although the distinct mallee form, known as the Yellow-rumped Pardalote
/P. p. xanthopyge/ was considered to be a separated species but with
reported interbreeding they have been considered separately here due to
their distinct habitat requirements. Schodde and Mason (1999) list three
subspecies with the small /P.p. militaris/ population isolated from
Cooktown south to about Mackay in Queensland.
