The Old World warblers have been split into several families, however, which leaves the barred warbler of central Eurasia (Sylvia nisoria), up to 36 g (1.3 oz) and 17 cm (6.7 in), as the largest "true warbler".[75] Not to be confused with the previous family, the largest of the well-known New World warblers is the aberrant yellow-breasted chat (Icteria virens), which can exceptionally measure up to 22 cm (8.7 in) and weigh 53 g (1.9 oz).[76][77] Another large family is the bulbuls, the largest of which is the south Asian straw-headed bulbul (Pycnonotus zeylanicus), to 94 g (3.3 oz) and 29 cm (11 in).
