In January 1990 I was on the STS Leeuwin, about 200 miles of the south coast of Western OZ, when we saw some birds skimming over the waves. One of the other "trainees" asked me what sort of birds they were and I said that I had no idea, and that they could be mutton birds for all I knew. It turned out that that is what they were. Apparently in the early days of the Colonies food was a bit scarce, so they started eating these birds - which tasted like mutton.
