Causes and consequences of nest site selection in cavity nesting birds

At the population scale, individuals use tree cavity nests which have different attributes that may affect reproductive success. I am investigating attributes such has cavity size, location, microclimate and excavation status on the growth and survival of flicker nestlings. At the community level, secondary cavity nesters depend on (and may compete with) primary cavity excavators for access to tree holes. I am investigating these relationships in collaboration with Dr. Kathy Martin (UBC).
