Camaróptera coliblanca Poliolais lopezi

Males appear overall gray, with a darker back and cap and a paler belly and throat. Females are similar but with reddish tones to the head. All individuals have extremely short tails with bright white outer tail feathers. An easily overlooked, diminutive warbler of montane forests, where it is often found in shaded thickets. Calls include a typewriter-like trill and nasal “nya nya nya” calls. Birds will sometimes duet, with the female giving nasal calls and the male giving clear, often paired whistles. Birds on Bioko also give a whistled “wheet” that rises in pitch.
