Émeraude de Gibson Chlorostilbon gibsoni

Small hummingbird with fairly limited range in Colombia and western Venezuela. Male is entirely emerald green with a mostly red lower mandible, although red color can be difficult to see. Females look different; pale grayish-white below with a white line behind eye, much like female Blue-tailed Emerald. Both sexes have a very dark tail. Look for singles feeding on flowers in dry woodlands and shrubby areas.
