White-throated Treecreepers in the ascendancy

["Mark Clayton" <>]

G'day Con,

I think just about every treecreeper species I have watched moves with both
legs together, not one at a time. I have also watched White-throated
Treecreepers moving along the underside of a branch where they move the same
way but don't open their wings. I have no idea as to how they stay upside
down without "dropping" as they move.

Cheers,
Mark

I have some evidence, but not conclusive evidence, in relation to the
following question:

'Do treecreepers hop up trees using two legs at a time, or do they step up
trees using one leg at a time?'
