An earlier post showed a Greater Racket-tailed Drongo (Dicrurus paradisus platurus) clinging onto a trunk of a tree in the manner of a woodpecker.
Lena Chow now has images showing a Javan Myna (Acridotheres javanicus) doing just what the drongo was doing. In the case of the myna, it did not use its tail for balance as seen in the drongo.
“It just holds onto the trunk with its claws while pecking away (above left), flapping its wings (above right) and perching again to move up and down the trunk,” wrote Lena. “The tree was too far away to see what it was feeding on, but probably ants…”
