The Chilean woodstar, endemic to Chile and Peru, is a small hummingbird in the Trochilidae family (BLI 2008). No larger than the size of a moth (Johnson 1967, p. 121), the Chilean woodstar is approximately 3 inches (in) (8 centimeters (cm)) in length and has a short black bill (BLI 2008; del Hoyo et al. 1999, p. 674). Males have iridescent olive-green upperparts, white underparts, and a bright violet-red throat (del Hoyo et al. 1999, p. 674; Fjelds[aring] and Krabbe 1990, p. 296). Females also have iridescent olive-green upperparts; however, their underparts are buff (pale yellow-brown) and they do not have a brightly colored throat (Fjelds[aring] and Krabbe 1990, p. 296).
