I was going to respond to Richard Baxter exactly as Carl Clifford has done. Although I suspect Richard was teasing. Actually all good points and fair to raise the issues yet again. But as others have commented, it is not exactly clear what happened in this case that Denise reported and who and how the birds were disturbed and what impact that had. Also about the suggestion of Carl Weber that “The bird protection law that I envisage would make it an offence to climb the tree, take eggs, shoot anywhere near the birds, camp within say 200 m, or in any way seriously disturb the nesting birds.” This would seem hard to envisage. Not every camper knows the difference between a Red Goshawk and a Galah, so expecting random travelling campers to know where such sensitive fauna (of many species) exist and avoid the area by as much as 200 m, would appear unlikely to happen.
