The Banded Woodpeckers (Chrysophlegma miniaceum) are common residents. They are often seen in pairs. And if the pair consists of males, they may indulge in their characteristic “dance” that may well be territorial display – swaying sideways and moving up the tree trunk. They may be on opposite sides of the trunk LINK or on separate hanging vines near to each other, as in Karyne Wee’s video below.
The Common Flameback (Dinopium javanense) apparently behaves similarly, as seen HERE.
