Sarus Cranes being disturbed by toggers

Just what I did not need today was yet another reason to be upset…. this time due to a couple of idiot photographers, a man and woman in late middle age both sporting 300mm lenses or some such, and who had scaled a farm fence near the Curtain Fig at Yungaburra and were walking across a field towards a large group of Sarus Cranes feeding. I suspect they were after flight shots, which they were undoubtedly about to get. Even more irritating was the fact that there were several close crane groups right by the fence just a little way down the road, easy to photograph from a car. I was surprised to see such thoughtless behaviour, maybe when you see a posting about Sarus Cranes near Yungaburra and dated Aug 22 on Facebook or Twitter someone could remind them about how to do things properly and not cause entirely unnecessary disturbance!
