Climacteris melanurus

White-browed Treecreeper
Climacteris affinis
The brown treecreeper (Climacteris picumnus) is similar in appearance to the white-browed treecreeper; however, the brown treecreeper's breast streaks are duller and ear-covert streaking confined to rear coverts. In addition, the brown treecreeper's short shrill 'peep' calls differ greatly to that of the white-browed treecreeper's long 'prrrpt' insect-like calls.
