Priorities for Future Research

Considering how widespread this species is, remarkably little is known about its breeding season ecology.  Intensive and laborious climbs to inspect cavities high in trees, as has been done with the Eurasian Nuthatch, will be needed.  Use of nest boxes may provide some opportunities in these studies.

Because they adapt so readily to captivity and can be kept in relatively small spaces, White-breasted Nuthatches are excellent animals for laboratory study.  Questions directed toward constructing a general theory of energy management could thus be explored with this species.  Such questions concern the relationship of short-term and long-term caching, why birds do not go deeper into hypothermia while roosting in winter, and how these factors and body mass are related to probability of nocturnal and diurnal predation (Grubb and Pravosudov 1994, Pravosudov and Grubb 1997).

Because they are permanent-residents with year-round territories, White-breasted Nuthatches have comparatively stable ecological and social lives.  Such stability can be capitalized upon to study in nature the interactions through the annual cycle of habitat patch areas and connectivity.  How do nuthatches estimate adequate patch complexes in winter and summer?  How does extent of connectivity affect breeding success and annual survivorship?
Long-term banding and breeding studies would shed light on survival and dispersal in this species, and life-time reproductive success.
