Cassin's Sparrow is a rather non-descript nomadic species of the southern Great Plains. They can be extremely common in some years and largely absent the next, with numbers often being much higher after good rains have resulted in relatively lush grasslands. Their nomadic behavior also includes occasional wanderings far beyond their normal range, as they have been found in states from coast to coast.
