Abstract:
A summary is presented of a study of the diurnal rhythmicity of perch-hopping in finches kept in artificial light-dark cycles. It is found that with an increase of lighttime, the activity-time of the bird increases. The phase angle difference, measured between midpoint of activitytime and midpoint of the light-cycle, follows the circadian rule, becoming more positive with an increase in lighttime. The results are in agreement with three rules describing the activity cycles of wild birds in the field at different seasons. Author
