Varied Sittella Shane Allwood originally shared: Varied SittellaAt first glance a foraging Varied Sittella may appear to behave rather like a treecreeper as it probes crevices in the bark of trees for insects and other invertebrates while scurrying about the branches and trunks. However, closer observation shows that sittellas spiral head-first down the trunks of trees, while treecreepers spiral up the trunks. There is much variation in the appearance of sittellas throughout their range, in mainland Australia — they appear so different that in years gone by many of them were treated as separate species.
