Measurements: •
Length: 5.1–5.9 in (13–15 cm) •
Weight: 0.5–0.6 oz (13–18 g) •
Wingspan: 8.7 in (22 cm) The male is easily recognized by its bright blue head and back (lighter than the closely related
indigo bunting), its conspicuous white wingbars, and its light rusty breast and white belly. The color pattern may suggest the
eastern and
western bluebirds, but the smaller size (13–15 cm or 5–5.9 inches long), wingbars, and short and conical bunting bill quickly distinguish it. The female is brown, grayer above and warmer underneath, told from the female indigo bunting by two thin and pale wingbars and other
plumage details. ==Call==
