Wild turkey numbers are falling in some parts of the US – the main reason may be habitat loss

But people killed them indiscriminately year-round – sometimes for their meat and feathers, but settlers also took turkey eggs from nests and poisoned adult turkeys to keep them from damaging crops.
Key Points:
- But people killed them indiscriminately year-round – sometimes for their meat and feathers, but settlers also took turkey eggs from nests and poisoned adult turkeys to keep them from damaging crops.
- Thanks to this unregulated killing and habitat loss, by 1900 wild turkeys had disappeared from much of their historical range.
- Turkey populations gradually recovered over the 20th century, aided by regulation, conservation funding and state restoration programs.
- We are wildlife ecologists working to determine why turkey populations are shrinking in portions of their range.
Fewer open spaces
- While turkeys may appear at home in urban areas, their habitat is open forest – areas with sparse trees that allow near-full sunlight to reach herbaceous plants at ground level.
- In 1792, naturalist William Bartram described the eastern U.S. as “Grande Savane,” or big savanna, a landscape with abundant wild turkeys.
- The open spaces that are left often are not suitable for wild turkeys: They need a well-developed layer of vegetation at ground level that includes mainly wild flowers, native grasses and young shrubs and trees to provide cover for nesting and raising their young.
- Turkeys can persist in these denser, shaded forests, but they don’t reproduce as successfully, and fewer of their young survive.
- Over the past 50 years, populations of bird species that live in open forests and grasslands have fallen by more than 50%.
The roles of food, predators and hunting
- For example, blame is often placed on more abundant predators that eat turkey eggs, such as raccoons and opossums.
- But these predators probably are more abundant in part due to changes in turkey habitat.
- This suggests that prescribed fire across the wild turkey’s range creates an environment that’s more favorable for turkeys than for their predators.
- Lastly, some observers have proposed that the timing of hunting could be affecting turkey reproduction.
Creating space for turkeys
- Land owners can help by managing for native grasses and wildflowers on their property, which will provide breeding habitat for turkeys.
- We have produced podcast episodes that discuss which plants are valuable to turkeys and other wildlife, and how to promote and maintain plants that are turkey-friendly.
