Why Do Woodpeckers Peck Wood?

Woodpeckers can peck 8,000 to 12,000 times a day and with a speed of up to 20 times per second. The impact force of the pecking is 1,000 times greater than the force of gravity, but because of the special design of the woodpecker's skull, it is able to direct the shock of impact away from the brain and protect it from serious injury. The woodpecker's skull is built to absorb shock and minimize the damage caused by constant, furious pecking. The bone and muscles that surround their brain are thick and spongy, helping the woodpeckers to prevent injuries to their brains and eyes. Furthermore, this remarkable adaptation has been the subject of research for developing better helmets and protective gear.

Woodpeckers peck on wood to look for food behind tree barks. They feed on tree-living or wood-borne insects. Some woodpeckers also feed on tree sap, native berries, fruits, nuts, and seeds. They use their sharp beaks to peck on tree branches and trunks to extract bugs. They also utilize their long tongues to reach into the pecked holes in the wood and trees to pull out the insects. In some species, the tongue can be extended to nearly three times the length of the beak, enhancing their ability to capture prey deep within the wood.

Woodpeckers also peck on wood to hollow out cavity nests. They are commonly found in wooded areas, wooden fence posts, utility poles, and buildings. Woodpeckers peck wood to make their holes, their habitats, in trees and wooden structures. They typically lay 4 to 8 eggs that hatch in their nests. This nesting behavior not only provides shelter but also protects their young from predators. A woodpecker is seen feeding its baby in the following picture. Interestingly, these cavities often become homes for other species after the woodpeckers have moved on, contributing to the ecosystem by providing shelter for various animals.

Pecking is also a form of communication for woodpeckers. They peck to flirt and attract mates, using their drumming as a mating call. Woodpeckers also use it to signal their presence to other nearby woodpeckers. This is why they will find surfaces that produce the loudest sound, as they want to be noticed by others of their species. Pecking is also used to establish their territory, to ward off predators and rivals with their 'drumming'. These communication skills are crucial during the breeding season when competition can be fierce.

Now that you know why woodpeckers peck, here are some fascinating facts that will help you understand the woodpecker's characteristic peck much better:

Effects of headbanging

One of the ill effects of woodpeckers' pecking is the damage they cause on trees and wooden structures, especially fruit and nut-bearing trees, wooden houses, and sidings. They also drum on metal or wood and peck things like TV antennas and chimney caps. However, as they are an indicator species, they are highly protected. This means their presence is often a sign of a healthy environment, as they thrive where there is an abundance of insects and healthy trees.

Calls

Woodpeckers are also known for their distinctive 'chick' calls. The sounds they make vocally tend to be simpler in structure compared to other passerine birds. These calls are used by both males and females for communication, courtship, territorial disputes, and alarm calls. Each species has its own range of calls. Mated couples may exchange muted, low-pitched calls to stay in contact. Their vocalizations, combined with their drumming, make them one of the most communicative bird species.

Species Diversity

There are about 200 species and nearly 30 genera in the woodpecker family. The diversity in the species is reflected in their calling sounds and physical characteristics. Their size can vary significantly, ranging from 7 cm to 50 cm, with the great slaty woodpecker being the largest surviving species. Some woodpeckers are monogamous, with mates typically holding large territories. It is rare to see more than two birds together at a time. When one member of a pair dies, the other usually finds a new mate. Woodpeckers' drumming (usually on metal or wood resonant surfaces) occurs from late winter through the spring, between January and April, when insects often stay inside their habitats in tree barks. It may occur several times during a single day and last for days or even months. Most woodpeckers are persistent and are not easy to drive away from their established territory, making them a tenacious presence in their habitats.
