Dogs are terrific for taking us to new and interesting places. If we didn't have a dog, we wouldn't have taken a walk along an ordinary-looking mud track in Heidelberg.
And if we hadn't gone there, we wouldn't have found ourselves alongside a flock of yellow-tailed black cockatoos.
They were noisy and busy, seemingly finding food - or something interesting, at least - under the bark of the little trees around us. It was wonderful to realise they didn't much care that we were there, and we could have stayed for hours watching them swoop and land and rip into the trees, but we did eventually tear ourselves away and continue the walk.
