| Résumé : | 1. Most nocturnal vertebrates cannot be watched during the greater part of their normal activities and successful photographs are often a matter of chance. 2. By means of infra-red radiation and a special telescope it is now possible to make continuous observations on nocturnal species which generally have poor sensitivity to light of the longer wave-lengths. 3. This technique has been successfully used to study and photograph the brown rat (Rattus norvegicus). |
