Characteristics and competition for nest cavities in burrowing Procellariiformes

Article Abstract:

Nest cavity dimensions, hatching success and competition for nest cavities were investigated to explain the structural differences of the Procellarriiforms breeding community between Cory's Shearwater and small petrels. Nest cavity characteristics between species revealed that nest cavity size was strongly related to species body size. Furthermore, high hatching success was observed on sheltered nest cavities. Competition between Cory's Shearwater and small petrels influences structure of the procillariiform breeding community.
