A Passer domesticus or house sparrow, what we in the New World refer to as an English sparrow, and look upon as an undesirable variety of winged varmint, got into a Dutch exposition center, where he made a nuisance of himself, interfering with a domino event by knocking down dominoes that over a hundred people from twelve countries had spent more than a month setting up. Exhibition authorities brought in an exterminator, who delivered retribution via pellet gun, but the Dutch Animal Protection Agency has placed English sparrows on its Endangered Species List (what’s next? cockroaches?) and is investigated the sparricide.
