DEVICE FOR FASTENING IN A SPECIFIC PROVISION AT LEAST ONE LIVE BIRD FOR REGISTRATION OF CHARACTERISTIC VIBRATION SPECTRA AND FOR DETERMINATION OF THE FLOOR

摘要

The present invention relates to an apparatus for locking at least one body part of a living bird in position for recording characteristic vibrational spectra, wherein the apparatus comprises a relief mask for inserting the body part to be locked in position, at least one movable supporting arm provided for locking the body part in position, and a sensor access with a light channel for directing the stimulation light irradiated by a light source onto the locked body part and for collecting the light back-scattered by the locked body part. The present invention further relates to devices and methods for determining the sex of living birds.
