The great spotted woodpecker, a striking black, white, and red bird, is a common sight (and sound!) in many woodlands. Their distinctive drumming, a rapid tattoo against tree trunks, echoes through forests and even gardens. But where do these industrious birds make their homes?
This article delves into the great spotted woodpecker nesting habits, exploring their preferred locations, the process of building their nests, and the fascinating details of their breeding cycle. Understanding great spotted woodpecker behaviour during nesting is key to appreciating these birds.
Where Do Great Spotted Woodpeckers Nest? Finding the Perfect Home
Great spotted woodpeckers are cavity nesters, meaning they build their nests inside holes, usually in trees. They don’t use existing holes made by other animals; instead, they excavate their own cavity, a process that can take several weeks. This is a key aspect of great spotted woodpecker nest construction.
Preferred Habitats for Great Spotted Woodpecker Nests
These adaptable birds can be found in a variety of habitats, but they prefer areas with plenty of trees, especially those that are dead or decaying. This is because dead wood is softer and easier for them to carve out. Here are some common habitats:
- Woodlands and Forests: These are their primary habitats, offering an abundance of suitable trees. Both deciduous and coniferous woodlands can be home to great spotted woodpeckers.
- Parks and Gardens: Even in urban environments, great spotted woodpeckers can thrive if there are enough mature trees. Larger gardens with a variety of trees are particularly attractive.
- Orchards: Orchards, with their mix of fruit trees, can also provide nesting opportunities, especially if some older, less productive trees are left standing.
What Kind of Trees Do Great Spotted Woodpeckers Use?
Great spotted woodpeckers aren’t too fussy about the specific type of tree, as long as it’s large enough and the wood is suitable for excavating. They prefer softer woods, especially those that are beginning to decay, as this makes the job of carving out the nest cavity easier. Some common tree species they utilize include birch, willow, alder, poplar, and oak.
They will even use harder woods like oak if decay is present. This is important to consider when thinking about what does a woodpecker nest look like from the outside – the tree itself is a big part of it!
The Nesting Process: From Excavation to Fledglings
The process of creating a nest cavity and raising young is a demanding one, requiring considerable effort from both parent birds.
Excavating the Nest Cavity
The great spotted woodpecker male and female play distinct roles. The male usually takes the lead in excavating the nest cavity. He uses his strong beak to chip away at the wood, creating a small entrance hole and then gradually hollowing out a chamber inside. The female may assist later in the process.
The cavity is typically located a few meters above the ground, offering some protection from predators. The entrance hole is usually quite small, just large enough for the adult birds to enter and exit.
Nest Construction Inside the Cavity
Once the cavity is complete, the woodpeckers line the bottom with wood chips, creating a soft bed for their eggs and chicks. They don’t bring in other nesting materials like twigs or leaves. This simple lining is what makes up the inside of the woodpecker nest.
Egg Laying and Incubation
The female great spotted woodpecker lays a clutch of 4-6 white eggs. Both parents take turns incubating the eggs, keeping them warm until they hatch. The incubation period lasts for about 12-13 days.
Raising the Young
Once the eggs hatch, both parents are kept busy feeding the chicks. They bring a constant supply of insects, spiders, and other invertebrates to the nest cavity. This is a significant part of the great spotted woodpecker diet. The chicks grow rapidly, and after about 20-25 days, they are ready to leave the nest (fledge).

Attracting Great Spotted Woodpeckers to Your Garden
If you want to attract great spotted woodpeckers to your garden, there are a few things you can do: Provide mature trees, leave dead wood, offer food like peanuts and sunflower seeds, and provide a water source.
The Importance of Great Spotted Woodpeckers
Great spotted woodpeckers play an important role in the ecosystem. By excavating cavities, they create homes for other birds and animals. They also help to control insect populations. While we’ve focused on the great spotted woodpecker, it’s worth noting that other woodpecker species, like the lesser spotted woodpecker, also contribute to the ecosystem in similar ways, although their nesting habits and preferences might differ slightly.
Conclusion
The great spotted woodpecker nesting habits are a fascinating example of nature’s ingenuity. From the careful selection of a suitable tree to the arduous task of excavating the nest cavity, their dedication to raising their young is truly remarkable. Understanding the great spotted woodpecker lifespan and the challenges they face highlights the importance of conservation efforts.
By understanding their needs and providing the right habitat, we can help these charismatic birds thrive in our woodlands, parks, and even our own backyards. The rhythmic drumming of a great spotted woodpecker is a welcome sound, a reminder of the vibrant life that exists within the trees around us.
FAQs
Do great spotted woodpeckers use the same nest cavity every year?
No, great spotted woodpeckers usually excavate a new nest cavity each year. However, they may sometimes return to an old cavity and renovate it.
How can I tell if a great spotted woodpecker is nesting in a tree?
You might see the birds actively excavating the cavity, carrying food to the nest, or hear the begging calls of the young chicks.
What do great spotted woodpeckers feed their chicks?
They primarily feed their chicks insects, spiders, and other invertebrates, providing them with the protein they need to grow. This is a crucial part of the great spotted woodpecker diet.
Are great spotted woodpeckers migratory?
In most regions, great spotted woodpeckers are resident birds, meaning they stay in the same area throughout the year. However, some populations may make short migratory movements in response to food availability or weather conditions.
How long do great spotted woodpeckers live?
Great spotted woodpecker lifespan is typically around 3-5 years, although some individuals can live longer. The first year of life is the most dangerous, with high rates of mortality. What does a woodpecker nest look like inside and out? Inside, it’s a simple chamber lined with wood chips. Outside, it appears as a small hole in a tree trunk, often in dead or decaying wood.
