This is the third time we have held a national training course on the ethics of working with birds in ecological-behavioural research. The course took place in the museum classroom and in the Zoological Garden. The course is offered every two years for researchers and students who study wild birds in the field or laboratory. In the first part of the course the participants heard Dr Mickey Harlev, manager of the veterinary service centre at Tel Aviv University, talking on the laws and procedures of conducting research on animals.  Prof Arnon Lotem then gave a broad review of the methods and problems of performing research on wild birds in nature and in captivity, followed by a lecture on veterinary and bird health, given by Dr Ron Elazari-Volcani. The last part of the course consisted in demonstrations and basic practice in the Zoological Garden.
