Green-throated Sunbird

An attractive, fairly long-tailed antwren found from eastern Venezuela and Guyana to southeastern Brazil. Males are grayish-brown above and black below with a white eyebrow and white sides. Also note bold white spots on wings and tail. Females are bright tawny below, with bold white wing spots and an indistinct white eyebrow. Look for pairs foraging in the lower levels of dense shrubby woodland, often remaining fairly hidden and difficult to see clearly. Typically occurs in the lowlands up to around 1,000 m. Listen for series of rather musical clucking notes.

Short-tailed antbird of forest understory. Both sexes have black face. Males are gray with white wingbars; females are brown above, buffy below, with cream wingbars and a white or buffy throat. Forages singly or in pairs low in the undergrowth of mature forest. Usually inhabits more mature forest than similar White-browed Antbird, but there is some overlap. Note differences in facial pattern; males lack the white eyebrow and females lack the orange eyebrow seen on White-browed Antbirds. Female Black-faced Antbirds also have browner underparts than White-browed. Listen for an even-paced series of 5–7 whistles that is slightly higher in the middle. In the southern part of its range, these whistles are pure-toned; in the north, they are harsher.

Long-tailed with long, slender bill that is sharply downcurved. Drab grayish-brown without any markings. Paler on throat; warmer orangey color on belly. Often hard to see when lurking in dense shrubs. Sings from prominent perches. Song is seemingly endless and complex. Forages primarily on the ground. Range restricted to dense brush and woodland in California and Baja California.
