Stephen,
What really surprised me, was seeing them climbing down the trunk,
rather like a Nuthatch. The NMs seemed to compensate for their lack of
the Nuthatch's specialised halluces, by using protruding bark flakes
as steps. Fascinating to watch.
Cheers,

White-plumed Honeyeaters imitate the call of Brown Treecreepers in

on the NSW South-west Slopes. Similarly to your NM situation, the
imitating
WPHEs are usually gleaning insects from under bark either on the trunk
or on
fallen timber (fallen tree limbs or logs). Very annoying when trying to
conduct transect surveys of Brown Treecreeper populations.

Dear B-A,
I have just been watching a Noisy Miner doing a fair imitation of a
Treecreeper on the trunk of a Eucalypt in my back yard. It was
climbing up the trunk, happily gleaning insects from under bark that
was lifting from the trunk. It was also climbing down the trunk, by
grasping flakes of bark in its claws. I saw another NM using the same
technique a couple of days ago. Is this a common behaviour in NMs?
Cheers,
Carl Clifford
