Sunda Pygmy Woodpecker

Certified Little Guy (tm) right here! Spotted foraging on a dead tree, as woodpeckers tend to do! The second photo is pretty funny to me! Just sticking their head right into the cavity of the tree!

Woodpeckers are always such fun to try to photograph! The way they circle up/down trees is somewhat predictable, but not so much so as to make it super easy!
