Ah... But see, you've got too many "e"s in there. And it's pronounced "care-o". It's Portuguese language, and it's the common name of an elegant shore bird from South America (the bird is actually called a "quero-quero" but that's even more of a mouthful). Here're a couple of images. There are other things to say about this bird's name, but this is probably more than you really want to know already!
