Someone is permanently employed at Sydney Airport to control large wading birds, including the locating of nests in nearby wetlands and destroying the eggs of ibis and other waders.

Why would this be totally bogus? The problem of bird strike by planes is a real one. Sure the risk is low.  My recollection from having analysed and compiled the reports from the relevant authority in Australia when I studied this issue some years ago (1988 I think), was that Canberra is not as big a problem as Townsville and Adelaide were but the issues are real. Bird habitat (for big birds) under the flight path is the major issue for bird strike reduction. About a year ago when there was a flock of (I think) hornets doing a very low and even more noisy pass over the area, as part of some display, a flock of high flying ibis that I observed there would have been on a collision course only a minute or two earlier. I can only tell from the ground but it sure looked to me like the planes would have needed to take evasive action if they were there a minute earlier. At the speed of their travel I think it would be hard to plan for this and I think birds would struggle to get out of the way. Flying in close formation I expect the pilots would have been competent and trained but it sure looked potentially scary to me at the time.

As we headed out of Queanbeyan this morning a Great Egret was wadfing in the dam opposite the end of Sutton rd beside Yass Rd.  2 White-faced herons also present.  Later as we drove down the Majura Parkway towards Pilligo a White-necked Heron (and a White-faced Heron) were wading in a small water body.  Finally, as we came past the airport Frances spotted at least 20 Straw-necked Ibis grazing on a lawn.  

 

Given the (IMHO totally bogus) concerns of the airport about birds from Kellys Swamp perhaps they should plough up their lawns as they are obviously a potential hazard right under the flight path.
