This Sora photo was taken in South Dakota. The bird we saw on Tuesday was barely visible. Despite the difficulty in seeing a Sora, the species is abundant in North American marshes. Even if hard to see, their loud whinnies are often heard (link curtesy Thayer Birding Software). Despite their being a game bird in many states, the main threat to Soras is wetland destruction. The etimology of the word Sora is unknown but presumed to be derived from a Native American language (Words for Birds: a Lexicon of North American Birds).
