Does Familiarity With The Release Site Influence The Initial Orientation Of Homing Pigeons? Experiments With Clock-Shifted Birds
FOA', Augusto Giuseppe Lorenzo;

Abstract
Experiments were performed to test whether the familiarity with the release site plays a role in the initial orientation of homing pigeons. Repeated releases of 6 h clock‐shifted birds from the same site during the shifting time produced an improvement of their initial orientation: the shift effect decreased progressively. Since in subsequent releases from unfamiliar sites the shift effect reappears, the course correction observed at the familiar site is attributable to local stimuli and not to a general recalibration of the sun compass. 1980 Blackwell Verlag GmbHFile in questo prodotto:
