Orange-billed Sparrow
Arremon aurantiirostris
The orange-billed sparrow is 14.5 to 16.5 cm (5.7 to 6.5 in) long and weighs about 35 g (1.2 oz). The sexes have the same plumage and all subspecies have the eponymous bright orange bill. Adults of the nominate subspecies A. a. aurantiirostris have a black crown with a gray stripe along its middle and a wide white supercilium on an otherwise black face. Their upperparts are olive-green and their wings and tail a darker olive-green with yellow at the bend of the wing. Their chin has a small black area and their throat is white with a wide black band below it across the upper upper breast. Voice: The orange-billed sparrow's song varies geographically though in general is "high-pitched, either a series of alternating lilting notes or thin whistles". In northern Central America it is an "extremely high-pitched series of sharp whistles" that lasts about two seconds; its call there is a "smacking tsiit!".
