White-breasted Nuthatches use mature, large-diameter oak trees for foraging and nesting cavities. They require high canopy cover in connected patches.
Limiting factors
Availability of mature oaks and cavities for nesting may limit distribution. Nuthatches are susceptible to nest predation and competition from European Starlings (Sturnus vulgaris) and other cavity-nesters.
Data gaps
Evaluate patch size requirements, dispersal ability, and potential for reintroductions.
Conservation actions
Maintain large oaks. Preserve trees containing cavities whenever possible. Promote development of larger oaks. Where possible, implement controlled burns to maintain oak tree dominance and prevent conifer encroachment.
