While I won't see huge flocks of birds in South Cottesloe as I did in Coral Bay, there are still quite a few kinds of birds that hang around the shore.
In South Cottesloe, the most common bird is the silver gull (Larus novaehollandiae) - as on many other Australian shores I guess.
Also frequently sighted in South Cottesloe is the pied cormorant (Phalacrocorax varius).
Pied oystercatchers (Haematopus longirostris) - I don't see them very often. Like silver gulls and pied cormorants, oystercatches are common all around the Aussie coastline.
White-faced heron (Egretta novaehollandiae) - I have seen this bird only once.
I don't know the name of this bird, but it certainly has a strong beak. Again, I have seen this bird only once. If it was 20 times larger, I might suspect it lived in the world of the dinosaurs. It had that look.
