We having "crossings" too: deer crossings, horse crossings, duck and goose crossings, and I'm sure lots more, like turkey crossings... You need to heed the wild animal ones because they usually mean the likelihood of needing to stop to avoid an accident is good. Don't you have any "koala crossings" or "kangaroo crossings"? Our signs are usually just a picture symbol of the crosser in question... :0)
