Hi Greg & Nick, I’m sure there’s no reason for alarm, but understand your vigilance. Disturbance from birders is definitely a threatening process http://www.iucnredlist.org/details/106005399/0 The last sentence of the “Threats” paragraph says it all. These birds are off the menu for birding tourism in this region, I’m sure Nick is aware of this. Cheers, Simon Clayton Manager Birdrangers, Gibraltar Reserve Cangai, NSW, 2460 www.birdrangers.com
