[catalyst2]

Watching the North Melbourne - St. Kilda game and there's a White-faced Heron on the pitch, looking very relaxed under the floodlights and the crowd. Of course, the commentators (Steven Quatermain, in particular, I think) decided that it was an ibis (from comments later on, I assume they meant the Australian Ibis) because they're so similar! D'oh!
