Family: Phylloscopidae
Genus: Phylloscopus
A rather unadorned leaf warbler commonly encountered in a range of wooded and scrubby environments, frequently in close proximity to water sources. Its identification is best achieved through its vocalizations: characterized by a slightly jerky double-noted chiff-chaff, chiff-chaff… song, distinctively different from that of the similar Willow Warbler. Compared to the Willow Warbler, the Chiffchaff is often duller, with a more brownish overall appearance, featuring a fainter pale eyebrow, dark legs, and a tendency to habitually dip its tail. While sharing similarities with the Booted and Sykes’s Warbler, the latter species are typically of a browner tone, with darker legs and bills.
