Abstract

Homing pigeons, kept from fledging time in cages supplied with screens to deflect the winds clockwise (CW) or counterclockwise (CCW), show a corresponding deflection in their initial orientation (Baldaccini et al., 1975). New experiments produced the following main results:
  1. 1.

    The acquired deflection in initial orientation was modified by subsequently reversing the arrangement of the deflectors, i.e., by subjecting CW-deflected birds to CCW-deflected wind and vice versa.

     
  2. 2.

    Birds reared in control cages, which had shown a normal initial orientation in test releases, deflected as expected three months after the deflectors had been applied to their cages. 3, The orientational bias of deflector-cage birds was not eliminated by repeated homing experience.
