Relationship between species richness of excavator birds and cavity–adopters in seven tropical forests in costa rica
The abundance of wood cavities is thought to be a limiting factor for bird species that depend on these cavities for nesting. Thus, it is expected that number of cavity adopters correlates with number of cavity excavators ...
