摘要：

Twelve series of releases performed with first flight pigeons reared in four Italian lofts are reported. The presence of preferred compass directions (PCDs) in the initial orientation of the birds is clearly evident, even if less pronounced than in other countries. Young birds show initial bearings which are less homeward oriented and more polarized towards a PCD than do older pigeons.
