Common Predators Threatening Upland Bird Nesting Success?

Predators of Upland Birds

Coyotes and red foxes are the primary mammalian predators of upland bird nests, with an estimated 70-80% of nests being lost to these predators in areas with low habitat diversity and fragmentation. Hawks, particularly red-tailed hawks and Swainson’s hawks, prey on upland birds, often targeting nests with vulnerable chicks. Control methods for coyotes and foxes include hunting, trapping, and repellents, while hawks can be deterred with nest protection methods and visual deterrents.

Habitat Management for Predator Control

Native grass restoration and Conservation Reserve Program (CRP) fields provide crucial nesting cover for upland birds, but these areas can also attract predators. Incorporating warm-season grasses, such as switchgrass and big bluestem, into restoration plans can help to maintain a diverse and dynamic habitat that benefits both birds and predators. By maintaining a mix of 20-30% warm-season grasses and 70-80% cool-season grasses, landowners can create a more resilient and complex habitat that supports upland bird nesting success while also limiting predator populations.

Best Management Practices for Predator Control

Best management practices (BMPs) for predator control in upland bird habitats include maintaining a safe distance between nesting cover and predator-attracting features, such as food sources and water, and implementing nest protection methods, such as nest boxes and visual deterrents. Additionally, maintaining a diverse and dynamic habitat through regular prescribed burning and rotational grazing can help to maintain a balance between upland bird populations and predator populations. By incorporating these BMPs into habitat management plans, landowners can help to maintain healthy upland bird populations and support biodiversity in native grass ecosystems.
