This bird derives its popular name from a peculiarity in 
the distribution of its two strongly contrasted colours, black 
and ferruginous, the latter of which covers the back, forms 
a sharply defined margin across the shoulders, and sweeps 
over the wings in a manner suggestive of saddle-flaps. A 
few years ago it was very plentiful in both Islands; but it 
has now entirely disappeared from the North Island, being 
met with only in some wooded islets in the Hauraki Gulf.

“ Piopio.” (Case IX. No. 10.) 
Named in compliment to Sir James Hector, Director of 
the Geological Survey Department. Formerly tolerably 
common in the North Island, but now one of the laicst of 
New-Zealand birds. This is much to be regretted, as it is 
a fine songster.
