The homing ability of a group of pigeons raised under conditions of continuous exposure to windborne information was compared to that of another group subjected to exposure to winds only during the time spent in pre-test training flights. The results

From fledging time up to the test releases, two groups of experimental pigeons were housed in two cubic cages supplied with deflectors which deviated the winds through to the inside approximately 70° clockwise (CW-birds) or counter-clockwise (CCW-bi

1. 1. Anosmatic pigeons are able to orient correctly and to home only when released at familiar sites. Very little is known, however, about what makes a site familiar to birds. 2. 2. The results of a series of experiments reported in this paper indic

During a treatment that lasted approximately 100 days beginning at fledging time, four groups of pigeons were kept for ten 3-day periods in an aviary of wire-netting located in Arnino. Here they could acquire a visual experience of the landmarks and

In order to test the nature of the information acquired by pigeons at home and utilized as “map” component in their navigational mechanism, groups of birds were kept since fledging time in glass corridors, which had their main axis oriented E-W (

From fledging time, two groups of homing pigeons were protected for most of the time from wind exposure. Instead, they were subjected to artificial odorous winds. One of the two groups was subjected to an odorous wind of olive oil from the S and an o

The initial orientation of pigeons with various degrees of homing experience was investigated in releases over the sea. The collected data encompasses 22 releases in which a total of 160 pigeons were used and 415 vanishing points recorded. The experi

Beginning from fledging time up to the time of homing experiments, 33 experimental pigeons were kept alternatively for three days in a wire-netting aviary which they could leave for spontaneous flights (O-aviary), and for three days in a closed aviar

Pigeons not experienced in homing and subjected to olfactory nerve section are generally found to be unable to home from short distances. In nine successive releases from different localities at 3.3 to 11.8 km from the loft, 15 out of 19 experimental
