Abstract
5 groups of ring doves, each consisting of 8 male and 8 female birds, were tested for incubation behavior by being placed in a cage with a nest and eggs. All birds had had previous breeding experience and had been kept in isolation for 3-5 weeks before being tested. The birds of one group were tested singly. The birds were tested in pairs in the other groups, which differed with respect to their treatment during the 7 days preceding the introduction of the nest and eggs into the cage. Birds tested singly failed to incubate. Birds placed in pairs in a cage with a nest and eggs incubated after 5-7 days. It was concluded that association with the mate and nesting material brings about the physiological changes underlying the onset of readiness to incubate.
