Early in 1969, at the request of the Director of Uganda Nationa Parks, Dr. Cott made a third survey of the status and biology of the Nile crocodile on the Victoria Nile below Murchison Falls, continuing the field studies he made in 1967 and 1968. This report on his 1969 work supplements that on the earlier studies (see ORYX, September, 1968) and reinforces his previous findings and recommendations. In 1969 the crocodiles again lost many eggs to predators, and the main cause was still human disturbance—by poachers and tourist launches. Once again, Dr. Cott urges that tourist launches must be kept away. The FPS is supplying a leaf-let to be given to all tourists explaining why.
