"Vulture," "Doves," and "Kingfishers" are all types of birds that are commonly found in various parts of the world. "Kiwi" refers to a bird native to New Zealand, which makes it the odd one out because it is not as widespread as the other birds. When identifying odd terms, consider geographical location or the type of species. In this case, "Kiwi" is a New Zealand-native bird.
