There are five species within the genus Spizella, which are found across North and South America. The species within the genus share several characteristics, such as their preference for open and grassy areas, and their ground-feeding habits. Synonyms for the term Genus Spizella include the word Spizella, which is the singular form of the genus, and the term American sparrows. It is important to note that not all small brownish birds are sparrows, as several closely related species such as finches and buntings may share similar morphological features.
