Seicercus

Seicercus is a genus of Old World warbler formerly in the Sylviidae family but now placed in Phylloscopidae. The genus is distributed in the Indian Subcontinent and eastern Asia from northern China to Timor in the Lesser Sundas. Many of the more northerly species are migratory, breeding in temperate climates and wintering in the tropics; others are attitudinal migrants, moving down from the mountains in the winter. A few species are migratory over part of their range and resident in others.
