Distribution. The Andaman Islands. This Tree-pie was obtained by Davison near Port Blair, where it was not uncommon; but he found it most numerous at Mount Harriet and Aberdeen. He observes that it is a forest bird and never ventures away from the cover of large trees; also that it never descends to the ground. I did not observe it on the Great Cocos nor on Table Island.
