This tiny bird is certainly an amazing creature! The bird in this video can fall a tree :)

A skilled carpenter. The Woodpecker’s head is its primary tool. And it’s highly evolved for the job. All woodpeckers have an enlarged brain case, so the brain sits above the level of direct hammering impact. The skull’s frontal bones, folded at the base of the bill, act as a shock absorber, together with a set of muscles there.

According to research by Audubon, each time a woodpecker drums on a tree to find food, build a nest, or attract a mate, it gets hit with up to 1,400 g’s of force—14 times the amount that would trigger a concussion in humans. Thankfully, the bird has a few ways to dampen the blow: built-in shock absorbers, an enlarged brain case, and a specialized beak and skull that redirect pressure away from its head. As if that wasn’t enough, it can also wrap its tongue around the back of its head to serve as a cushion (when the organ isn’t being deployed to trap dinner, of course).

Now out comes the woodpecker’s amazing tongue, at least three times the length of its bill, with sticky barbs at the tip, to snag ants and other insects deep in the tree. When not extended, the tongue is sheathed up the back of the bird’s skull, curling all the way around to the eyes!

Woodpeckers excavate their own nests. A typical nest has a round entrance hole that just fits the bird, leading to an enlarged vertical chamber below. No nesting material is used, apart from some wood chips produced during the excavation; other wood chips are liberally scattered on the ground providing visual evidence of the site of the nest.

Many species of woodpeckers excavate one hole per breeding season, sometimes after multiple attempts. It takes around a month to finish the job and abandoned holes are used by other birds and mammals that are cavity nesters unable to excavate their own holes.

The majority of woodpecker species live up to their name and feed on insects and other invertebrates living under bark and in wood, but overall the family is characterized by its dietary flexibility, with many species being both highly omnivorous and opportunistic. The diet includes ants, termites, beetles and their larvae, caterpillars, spiders, other arthropods, bird eggs, nestlings, small rodents, lizards, fruit, nuts and sap. Many insects and their grubs are taken from living and dead trees by excavation. The bird may hear sounds from inside the timber indicating where it will be productive to create a hole.
