Next stop was the Stirling Ranges and Stirling Range Retreat specifically. On my way down there, I acted upon some local information [thanks Deb] and drove the road from Donnybrook to Boyup Brook and return; twice. This was my best chance of seeing Baudin's Black-Cockatoo. The idea was to drive as slow as practicable with the windows open listening out for the calls. And that is what happened. A small flock of 8-10 were feeding/resting in a patch of bush on the old railway easement on the roadside near Mumballup. A quick pullover, jump out and I was able to take plenty of photos after a good long look with the bins. Yippee. Tick.
