Our data do not permit firm conclusions about food limitation and 

 habitat preference, but they can be used to suggest areas of future 

 research. We believe that it is worth investigating whether winter 

 survival of red-cockaded woodpeckers is a significant factor influencing 

 population size and structure and influenced by winter foraging 

 conditions, and if so, whether foraging conditions are related to 

 manageable characteristics of forests.
