The mating and nesting behavior of woodpeckers ranges from compassionate to violent. Although there are a variety of woodpecker species, many of the members of this group share similar mating qualities, with a few notable exceptions.

Woodpecker courtship

Next time you hear a woodpecker hammering away outside your window, he or she may be trying to communicate with a member of the opposite sex. Woodpeckers are primarily monogamous, although polygamous species do exist.

Courtship often begins with drumming, display flights and calls. Drumming can be used to advertise territory, alert a potential partner to a specific tree hole or to personally another woodpecker.

Woodpeckers are a highly aggressive species and courtship often trigers territorial behavior between other males and between potential mates.

Black woodpecker males engage in a ritual called 'threat courtship,' where the birds will threaten each other with calls before flying to a base of tree and attempting to drive each other upward.

Interactions between potential mates can also be fairly aggressive during courtship, though, once he feels more insecure, the male's aggression usually subsides.

Woodpecker Holes

Woodpeckers are cavity nesters. They create their own nests by excavating wood from trees and rarely use nests from previous years. Excavation of holes typically takes woodpeckers 10-28 days. This construction is usually done by both the male and the female; sometimes the pair will produce one hole for breeding and another for roosting later in the year.

Woodpecker Copulation and Nesting

Woodpecker copulation lacks any sort of ceremony. The female gathers the breeding position while stretched out on a branch and the male mounts her from behind.

Eggs are typically laid in the morning and the size of the clutch is between four and six eggs. The incubation period is approximately 10-14 days and both the male and female guard the eggs during this period, usually rotating every 30-50 minutes.

The nestling period is 18-35 days, and after leaving the nest, the young birds often return to spend time with their parents in the territory for 1-8 weeks. Sometimes, the parents drive them away and they become completely independent.

Conclusion

The woodpecker is one of the world's most iconic bird species. When it's hammering away at a tree with its trademark bill, which is used not only to harvest food, but also to communicate, it's unmistakable. The mating and nesting behavior of woodpeckers ranges from compassionate to violent. Although there are a variety of woodpecker species, many of the members of this group share similar mating qualities, with a few notable exceptions.
