Nest-site fidelity and cavity reoccupation by Blue-fronted Parrots Amazona aestiva in the dry Chaco of Argentina
The frequency of cavity reoccupation in secondary cavity nesters depends on several factors including quality of cavities, degree of nest-site fidelity, competition with other cavity nesters and availability of new cavities. Blue-fronted Parrots Amazona aestiva are secondary cavity nesters that live...
