Woodpeckers bash their heads against wood about 20 pecks every second, so you'd think they'd need heads made of steel to survive. Instead, the reality is that woodpecker heads are relatively soft. Each bird is born with a soft, sponge-like mass behind its beak that absorbs the shock created by pecking.
Their beaks are made from a material much harder than the wood.
Because they need to peck into the trees
To get food such as beetles and worms in the wood.
It helps them to get bugs from trees
Woodpeckers eat bugs that live under tree bark, like termites. So they peck holes in the wood and use their extremely long tongues to pick up their prey. And they drill cavities in trees suitable for their size as a nest.
To allow them to feed on insects and various other creatures through the hole in the bark of the trees.
All species of woodpeckers have strong beaks. They also have a head structure that enables them to constantly and very rapidly to bash their beak into wood in search of grubs - without damage to their brain!
so that they can survive and to reach the leaves on trees
The fig trees can survive cause they grow really fast even with little water, and because they are sort of like cactus and hold water for a long time. :)
They use the long neck to eat leaves off of trees.
Woodpeckers are near passerine birds of the order Piciformes. They are found worldwide and include about 180 species. Woodpeckers gained their English name because of the habit of some species of tapping and pecking noisily on tree trunks with their beaks. This is both a means of communication to signal possession of territory to their rivals, and a method of locating and accessing insect larvae found under the bark or in long winding tunnels in the tree.
woodpeker are famous for their long,strong and sharp beak.
They are herbivores so They survive by using there long necks to reach the trees and eat the leaves on there. Also with there tallness most predators do not go for them because Giraffes are bigger then them. :)
