Interestingly, the Eurasian Coot is cosmopolitan, very common in wetlands in Sydney, such as Sydney Olympic Park and Centennial Park. The Northern Plover/Lapwing is from the same family (Charadriidae) as Masked Lapwing which is common in Sydney. That bird nests in most unlikely places, open grassy play fields. But is seems to thrive, thanks to very mindful rangers and local birders, who help protect its eggs and chicks, and the visitors as well. That bird has prehistoric claws in its wings and is very vigilant and can attack. I was attacked once at Sydney Olympic Park and that was enough to learn my lesson.
You might be interested in seeing White-bellied Sea Eagles nesting at Sydney Olympic Park (via 24 hr live-cam). They just about finished renovating their nest and will be laying 2 eggs soon. The nest is in the forest behind Birdlife Discovery Centre where I volunteer.
