The red-cockaded woodpecker is an endangered species native to the southeastern United States. This medium-sized woodpecker has been declining in numbers due to loss of its preferred open, mature pine habitat. Efforts are underway to protect existing populations and restore lost habitat. Key measures include habitat conservation, relocation of woodpecker groups, installation of artificial cavities, and public education campaigns. With continued efforts, it is hoped the red-cockaded woodpecker can make a recovery.
What is the red-cockaded woodpecker?
The red-cockaded woodpecker (Picoides borealis) is a medium-sized woodpecker species found in the southeastern United States. Some key facts about this bird:
- Adults are black and white with barred wings and flanks. Adult males have a small red streak on each cheek, hence the name “red-cockaded.”
- They are about 7-9 inches in length with a wingspan of 13-16 inches.
- They prefer to nest in mature pine forests, especially longleaf pine.
- They are the only woodpecker species that excavates cavities in living pine trees.
- Their range once covered 90 million acres but is now reduced to 3 million acres.
- There are only about 5,000 groups remaining with 14,000 total adults.
- They are listed as endangered under the Endangered Species Act.
The red-cockaded woodpecker plays an important role in its ecosystem. The cavities it excavates provide habitat for many other species. Its decline is a symptom of the destruction of the once vast longleaf pine ecosystem across the southeast. Protecting it requires protecting and restoring this ecosystem.
Why is the red-cockaded woodpecker endangered?
The red-cockaded woodpecker has declined to endangered status due to loss of its preferred mature pine habitat across the southeastern United States. Here are some of the main factors that have contributed:
- Habitat loss – The longleaf pine ecosystem once covered over 90 million acres from Virginia to Texas. Intensive logging in the late 19th/early 20th centuries removed most old-growth pine forests. Remaining stands are fragmented.
- Shorter timber rotations – Today’s pine plantations are harvested at younger ages, before pines develop the older characteristics required by the woodpeckers.
- Fire suppression – Fire suppression has allowed hardwoods to encroach on pine stands, making them unsuitable habitat.
- Increased nest predation – Loss of mature pines and habitat fragmentation leaves nests more vulnerable to predators like snakes and rats.
- Parasitism – Brown-headed cowbird parasitism has impacted reproductive success.
The woodpeckers require large areas of older growth pine savannah to thrive. Their specialized behaviors also make them vulnerable. The result has been a dramatic decline from an estimated 1.6 million groups historically to only about 5,000 today.
How do red-cockaded woodpeckers make their homes?
Red-cockaded woodpeckers make their homes by excavating cavities in living pine trees, a very specialized behavior:
- They prefer older pines 60-120 years old and at least 14 inches in diameter at breast height.
- Cavities are excavated over 1-3 years of chipping away at the heartwood.
- Resin wells are kept open above and below cavities to serve as defense against predators.
- Each group may have up to 20 trees prepared with cavities for roosting and nesting.
- Cavities are lined only with wood chips.
- Cavity trees may be used for decades and are passed down through generations.
This cavity excavation provides crucial habitat for other species after woodpeckers abandon them. Over 20 species are known to use red-cockaded woodpecker cavities, including chickadees, bluebirds, screech-owls, wood ducks, flying squirrels, and pine snakes. The woodpeckers prefer to nest in groups cooperatively, with adult “helpers” assisting parents raise young. Their survival depends on mature pine savannahs with large, old pines and little understory vegetation.
What laws protect the red-cockaded woodpecker?
The red-cockaded woodpecker receives legal protection under the following laws:
- Endangered Species Act – Listed as endangered in 1970, giving it protection from harm or harassment and requiring conservation efforts.
- Migratory Bird Treaty Act – Makes it illegal to disturb nests or cavities as with other native birds.
- Lacey Act – Prohibits transport of illegally captured red-cockaded woodpeckers across state lines.
- State laws – State wildlife agencies implement protections through permits, fines for violations, and habitat acquisition.
The U.S. Fish and Wildlife Service oversees implementation of the Endangered Species Act and related recovery plans. State wildlife agencies and landowners also play key roles in protecting nesting sites and habitat on public and private lands through conservation plans, safe harbor agreements, and other measures.
What conservation efforts are helping the red-cockaded woodpecker?
Many conservation efforts are underway to help protect and recover red-cockaded woodpecker populations. Some major initiatives include:
- Habitat conservation – Acquisition and management of public and private lands to protect pine savannahs.
- Prescribed burning – Uses controlled burns to restore open understory preferred by the birds.
- Translocations – Relocates woodpecker groups to supplement small populations.
- Artificial cavities – Installs man-made cavities when old pines are not available.
- Nest boxes – Provides nesting boxes to reduce brown-headed cowbird parasitism.
- Public education – Outreach campaigns help build public support to save the species.
Major partners in conservation include federal and state agencies, nonprofits like The Nature Conservancy, forest industry, and private landowners. Recovery goals aim to increase populations, connect fragmented habitats, and restore savannah conditions needed for thriving, self-sustaining woodpecker populations.

How can prescribed fire help red-cockaded woodpeckers?
Prescribed fire is an important habitat management tool that benefits red-cockaded woodpeckers in several ways:
- Reduces hardwood competition – Fires restrict growth of oak and other hardwoods that encroach on pine stands.
- Opens up understory – More open structure preferred by woodpeckers for nesting and foraging.
- Reduces brown-headed cowbirds – Can limit this brood parasite.
- Creates foraging habitat – Increase of beetles and other prey after fires.
- Stimulates new growth – Fresh pine growth after fires provides future nesting habitat.
Proper use of prescribed fire helps maintain the pine savannah conditions the red-cockaded woodpecker evolved with. Burn frequency of 1 to 3 years can mimic natural fire cycles. However, care must be taken with fire during the nesting season. Overall, prescribed burning is a valuable tool when applied properly by trained natural resource professionals.
What is artificial cavity installation and how does it help?
Artificial cavity installation is used to supplement populations where older pines needed for cavities are lacking:
- Inserted into smaller pines not usually selected, extending useable life.
- Custom-built cavities made of composite wood, resin, and aluminum.
- Tunneled into tree core with entrance hole drilled.
- Resin wells added and interior cleaned before use.
- Monitored and maintained to prolong utility.
- Allow new groups to form and increase breeding potential.
This technique expanded useable nesting sites and helped stabilize populations. However, it is still important to protect and restore sufficient older pine stands to support self-sustaining woodpecker groups long-term. Approximately 15,000 artificial cavities have been installed across the southeast. They are a helpful short term remedy but do not replace natural pine habitat.
How can private landowners help the red-cockaded woodpecker?
Private landowners control about 70% of remaining red-cockaded woodpecker habitat, making them critical partners in conservation efforts. Landowners can help by:
- Learning to identify red-cockaded woodpeckers and cavity trees on their land.
- Participating in Safe Harbor agreements to manage habitat without additional restrictions.
- Implementing prescribed burning to maintain optimal pine structure.
- Controlling hardwoods encroaching on pine stands.
- Installing artificial cavities if needed to support populations.
- Pursuing sustainable limited timber harvest that retains old pines.
- Preventing damage to cavity trees during forestry operations.
Financial and technical assistance is available through government and nonprofit programs to plan and implement red-cockaded woodpecker conservation on private lands. With landowners’ help, significant habitat gains can be achieved to move the woodpecker toward recovery.
What reforestation strategies help the red-cockaded woodpecker?
Reforestation strategies are shifting pine plantation management in directions that can benefit the red-cockaded woodpecker:
- Longer rotations of 80+ years allow older pine characteristics to develop.
- Retention of legacy trees during harvest provides cavities.
- Planting straight rows with wide spacing creates more open structure.
- Use of prescribed fire maintains grassy understory.
- Retention of standing dead trees and downed logs as foraging sites.
- Connecting corridors of suitable habitat across property boundaries.
While plantations lack the diversity of native longleaf pine ecosystems, changes in plantation design and management can create pockets of improved habitat for red-cockaded woodpeckers while still allowing timber production.
What is the outlook for the future of the red-cockaded woodpecker?
The outlook for the red-cockaded woodpecker remains challenging but conservation efforts have stabilized populations and offer genuine hope:
- Steady populations for last 20+ years after dramatic declines.
- Protection efforts now include over 1 million acres of habitat.
- Significant longleaf pine restoration underway.
- Better understanding of management needs through research.
- Increased prescribed burning on public and private lands.
- More involvement by forestry and land management communities.
Full recovery is still dependent on sustained efforts to conserve existing populations, recruit more adult woodpeckers, restore lost old-growth habitat, and maintain optimal conditions through prescribed fire and other management. With ongoing teamwork between government agencies, nonprofits, landowners, and researchers, the woodpecker has a fighting chance to once again thrive in the southeast.
Conclusion
In summary, the red-cockaded woodpecker has declined to endangered status due to loss of the southeast’s native longleaf pine ecosystem. Ongoing conservation efforts focus on habitat protection, management with prescribed fire, artificial cavities, relocations, forest management changes, and private landowner involvement. While challenges remain, the dedicated work of many partners has stabilized populations and offers hope for the future. The woodpecker serves as a symbol of both the grave impacts humans can have on nature and the potential through cooperative action to reverse past mistakes. The bird’s specialized nature makes it a challenging species to conserve and restore, but the pine savannahs it depends on support an incredible diversity of other plants and animals. Saving the red-cockaded woodpecker ultimately yields much broader benefits.
