Mark Twain talking to a naturalist onboard a ship, in Following the Equator:

He told me that the first pair of rabbits imported into Australasia bred so wonderfully that within six months rabbits were so thick in the land that people had to dig trenches through them to get from town to town.

For those who may have heard Biden referred to as a “Sundowner”:

He told me a great deal about worms, and the kangaroo, and other coleoptera, and said he knew the history and ways of all such pachydermata. He said the kangaroo had pockets, and carried its young in them when it couldn’t get apples. And he said that the emu was as big as an ostrich, and looked like one, and had an amorphous appetite and would eat bricks. Also, that the dingo was not a dingo at all, but just a wild dog; and that the only difference between a dingo and a dodo was that neither of them barked; otherwise they were just the same. He said that the only game-bird in Australia was the wombat, and the only song-bird the larrikin, and that both were protected by government. The most beautiful of the native birds was the bird of Paradise. Next came the two kinds of lyres; not spelt the same. He said the one kind was dying out, the other thickening up. He explained that the “Sundowner” was not a bird it was a man; sundowner was merely the Australian equivalent of our word, tramp. He is a loafer, a hard drinker, and a sponge. He tramps across the country in the sheep-shearing season, pretending to look for work; but he always times himself to arrive at a sheep-run just at sundown, when the day’s labor ends; all he wants is whisky and supper and bed and breakfast; he gets them and then disappears.
