Savannah Sparrows are medium-sized sparrows with short, notched tails. The head appears small for the plump body, and the crown feathers often flare up to give the bird’s head a small peak. The thick-based, seed-eating bill is small for a sparrow. Savannah Sparrows are brown above and white below, with crisp streaks throughout. Their upperparts are brown with black streaks, and the underparts are white with thin brown or black streaks on the breast and flanks. Look for a small yellow patch on the face in front of the eye. https://www.allaboutbirds.org/guide/Savannah_Sparrow/id
