Recent Technologies for Wildlife Monitoring

Animal welfare has become an essential focus in modern zoological institutions. Zoos are no longer viewed only as places for public display; they are also centres for conservation, research, and animal care. Because of this shift, researchers and zoo managers are increasingly interested in developing reliable methods to evaluate the well-being of animals living under human care.Traditionally, welfare assessment relied mainly on behavioural observations, veterinary examinations, and measurement of stress-related hormones. Although these approaches provide useful information, they have several limitations. Observations can only be carried out for limited periods and animals may hide signs of stress or illness. Monitoring large numbers of animals can also be difficult.
