PASSERIFORMES: Turdidae
Zoothera heinei
The differences between Bassian Thrushes and Russet-tailed Thrushes are so small that it is very hard to tell which is which.
This is taken in an area that has both and I am not really sure which one this is.
Bushpea thanks Dezmond Wells, Eremaea eBird moderator, for assistance with this identification.
