Re: Thornbill ID

I saw an interesting  thornbill
on the weekend which had markings that i couldn't identify from the field
guide. 

It had a rich bright chestnut rump (as
chestnut-rumped thornbill), but the marking that made it look odd was a
similarly coloured chestnut forehead and crown.

Simpson and Day list the forehead on
chestnut rumped thornbills as light brown. 

Does anyone familiar with chestnut rumped
thornbills, know whether thier crown/forehead can appear chestnut, or whether
this is maybe a juvenile marking?

Thanks in advance, 

Peter
