Of course there is the organised parrot feeding where you have the chance to give some provided food to these beautiful birds. However, while having a break in the café I saw a family who gave sugar to a parrot! They just poured some sugar on the floor and the parrot came and ate it.
Of course this is not desirable and not healthy at all for the birds. I informed the waiter and he told the people to stop it, and was quite happy that I had informed it. So if you spot something like this, don't hesitate but tell the people who are responsible.
Although the animals at O'Reilly's are of course quite used to humans, it is still a national park and they are protected, so we should not give unhealthy food to them!
...even though I could not resist to take a picture, as this was such a good photo opportunity ;-)
Notify friends or neighbours where you are going and how long you expect to be; a general rule of thumb is to allow yourself to cover 3km an hour.
DO NOT leave the walking tracks, as it is easy to become lost; especially in dense rainforest.
At night bring what you can inside the tent. The scrub turkeys will be all over your gear, looking for something to eat, or satisfying their curiosity. Even during the day, hang food up in a tree, out of reach of these birds.
In case you get forgetful, the more heavily travelled circuits at O'Reilly's come with a warning. Stay away from the edges, it can be a steep drop. And it could be added, stay on the clearly marked paths.
