<Li> Tyladidae Oberholser, 1917 </Li> <Li> Spizixidae Oberholser, 1919 </Li> <P> The bulbuls are a family, Pycnonotidae, of medium - sized passerine songbirds . Many forest species are known as greenbuls, brownbuls, leafloves, or bristlebills . The family is distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan . A few insular species occur on the tropical islands of the Indian Ocean There are over 150 species in 27 genera . While some species are found in most habitats, the African species are predominantly found in rainforest whilst rainforest species are rare in Asia, instead preferring more open areas . </P> <P> The traditional layout was to divide the bulbuls into four groups, named Pycnonotus, Phyllastrephus, Criniger, and Chlorocichla groups after characteristic genera (Delacour, 1943). However, more recent analyses demonstrated that this arrangement was probably based on erroneous interpretation of characteristics . </P>
