Peucaea cassinii, commonly known as Cassin's Sparrow, is a subtly beautiful and often elusive songbird of the arid grasslands of North America. Measuring approximately 5 to 6 inches (13-15 cm) long with a wingspan of 7.5 to 8.5 inches (19-22 cm) and weighing about 0.6 to 0.8 ounces (17-23 g), it is characterized by its grayish-brown plumage finely streaked on the back and flanks, giving it a distinctive scaled or scaly appearance.
