Abstract
During the past 25 years, interest has gradually focused on research which allows study animals to live in their normal environment. Initially it was thought that if animals were undisturbed and were allowed to become familiar with unnatural conditions, then subsequent changes in behaviour might be insignificant or nonexistent. However, both laboratory and caged field conditions were later found to alter observable behaviour patterns. The more subtle, but equally important physiological changes were suspected but remained unmeasurable because of technological limitations. The concerned scientist then looked for techniques which would permit animals to remain in their natural habitat and which would also minimise behavioural and physiological changes. Biotelemetry (that is data transmission of biological information without direct connection between transmitter and receiver; see figure 21.1) was suggested as a possible solution to these problems. Different modalities including light, ultrasonics and radio have been used in various situations, but radiotelemetry has so far provided the most generally useful and adaptable approach (Mackay, 1974).
Charles Amlaner is a graduate of Andrews University, Michigan, U.S.A., where he received degrees in Biophysics and Zoology. He has been involved in experimentally evaluating the communication schemes of several gull species using remote controlled models of his own design and construction. Two years were also spent working under a US Air Force and Smithsonian Institute sponsorship assessing the most humane methods to rid aerodromes of gulls. As a member of Oxford’s Animal Behaviour Research Group, he is currently using biotelemetry as an aid to study sleep patterns in free-ranging Herring gulls.
