In natural areas, stream water can contain organisms which cause diarrhoea and other illnesses and should always be boiled or treated before drinking. Beware of the sun's harmful rays. There is still a risk of sunburn on overcast days as UV rays can penetrate clouds. Wear sunscreen, a hat and appropriate clothing to protect yourself from prolonged exposure to the sun. Never feed or play with animals.
Human food is inappropriate for native animals and can lead to malnutrition.
Feeding can create an imbalance in their population size. Unpredictable and aggressive behaviour can result from hand feeding.
