The Phaenicophilidae family comprises passerine birds that are unique to Hispaniola. Within the family, there are four species spread across three genera: Phaenicophilus, Xenoligea, and Microligea. Historically, species from these genera were grouped with the Thraupidae and Parulidae families. The Black-crowned tanager (P. palmarum) and Grey-crowned tanager (P. poliocephalus) belong to the Phaenicophilus genus. The Xenoligea genus is home to the White-winged warbler (X. montana), and the Microligea genus includes the Green-tailed warbler (M. palustris). These species contribute to the rich biodiversity exclusive to their island habitat.
