The Cettiidae family, often referred to as cettiid warblers, is a group of small, primarily insect-eating songbirds that used to be lumped with a diverse set of "Old World warblers." The family, recognized in 2006, is primarily distributed across Asia and extends into Oceania and Europe, with only Neumann's warbler found in Africa. These birds, which include the genera Cettia, Horornis, Urosphena, Tesia, and others, inhabit forests and scrublands where they actively forage through dense foliage. Most cettiid warblers exhibit dull plumage and have moderate to long tails, except the stubtails and tesias, which feature very short tails. While the majority of the species are non-migratory, a few, such as the Asian stubtail, do migrate, and some others, like the Cetti's warbler, exhibit partial migratory behavior. There are 31 recognized species within the family Cettiidae, which is considered by some taxonomists to be a part of the larger Scotocercidae family, and they are often grouped with their relatives in field guides for ease of identification.
