White-throated Tinamou (Tinamus guttatus)

White-throated Tinamou

Tinamus guttatus Gallineta Chica

Identification: 13.5" (34cm). 600g. Eyes brown; legs dull greenish. Med.-sized tinamou with spotted rear-parts. Crown sooty black, sides of head and neck cinnamon buff flecked black; back, wings, and tail dark brown thickly dotted buff to whitish and coarsely and inconspic. barred black; throat white, chest buffy brown turning buffy white on lower underparts; thighs and flanks barred dusky (often faint), under tail coverts dull rufous.

Sim. species: Looks like a small version of Great Tinamou with conspic. pale spotting on rearparts. Contrasting cap, throat, and spotting are the marks.

See Undulated, Variegated, Gray-legged, and Barred tinamous.

Parrish recording).


Behavior: Sim. to others of genus. Four BC birds, late Mar-late Apr, Cerro Yapacana185.
