If they are insect eating woodpeckers then they aren't harmful. Also, if they eat dead wood they aren't. BUT, if they eat fresh tree wood, then they are absolutely harmful. Also, do not harm these birds! (:
No, what they are after is insects that are infesting the tree, if a woodpecker is on a tree it is already sick from harmful insects, let the woodpecker do his job and he will eat them for you.
they aren't harming the trees they are just making small dents or holes in the trees.
They hammer their heads into a tree with a force of 15mph 20 times per second.
Not as a rule
NO
A Woodpecker does
A woodpecker, when trying to get bugs in a tree, uses its sharp beak to "drill" a hole in the tree, making loud tapping noises, hence the name "woodpecker"
The woodpecker uses nothing but his beak . He keeps on pecking at the tree to make a big hole which is known as his nest .
The woodpecker loves to make holes in trees.You might see some in the forest.
The Woodpecker Tree Decoration has metal stakes that it attaches to the tree with.
woodpeckers do not damage healthy trees, they make a hole in a tree infected with parasitic insects to eat the problem bug, a small hole in a healthy tree will heal, but if they are able to make a bigger hole it is because that wood was already dead.
Every movement you make requires friction. When you walk, it requires friction. When a woodpecker is pecking a hole in a tree, it requires friction for him to keep his toes in the tree- static friction, to be specific. Hope that helped!
It is a hole in any piece of wood, for example, a hole in a tree in the novel, To Kill a Mockingbird.
it doesnt the relation between both the organisims is parasitism which means one organism benifites off of the other and the other one gets harmed in some type of way. in this case the woodpecker gets food and shelter from the tree while the tree gets harmed by having a hole on it.
no
