Chapin's Crombec
 The Chapin's Crombec (Sylvietta leucophrys chapini) is an enigmatic African warbler formerly placed in the family Sylviidae. It is currently considered a subspecies of the White-browed Crombec but might be a distinct species; too little is known about it to determine this now with reasonable certainty.It is found only on the Lendu Plateau Democratic Republic of the Congo.
