“Here is a video of a male Laced Woodpecker (Picus vittatus) feeding on a shaky branch by using its beak to peck at the branch. The frightened little insects will quickly scramble out of the loosened tree bark which allows the bird to use its sticky tongue to lick them up.
“This video shows clearly its zygodactyl feet (two front pointing and two back pointing clawed toes on each foot), which is useful for climbing and balancing while pecking at the branch.”
