Eurillas
''Eurillas'' is a genus of greenbuls, passerine birds in the bulbul family Pycnonotidae. Taxonomy The genus ''Eurillas'' was introduced in 1899 by the American ornithologist Harry C. Oberholser with the little greenbul as the type species. The genus name combines the Ancient Greek ''eurus'' meaning "broad" or "wide" and ''illas'' meaning "thrush". This genus was formerly synonymized with the genus '' Andropadus''. A molecular phylogenetic study of the bulbul family published in 2007 found that ''Andropadus'' was polyphyletic A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of conver .... In the revision to the generic classification five species were moved from ''Andropadus'' to the resurrected genus ''Eurillas''.

Little Grey Greenbul
The little grey greenbul (''Eurillas gracilis'') is a species of the bulbul family of passerine birds. It is widely distributed across the African tropical rainforest. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical swamps. Taxonomy and systematics The little grey greenbul was originally described in the genus '' Andropadus'' and was re-classified to the genus ''Eurillas'' in 2010.

Greenbul
The greenbuls are a group of birds within the bulbul family Pycnonotidae, found only within Africa. They are all largely drab olive-green above, and paler below, with few distinguishing features. The "aberrant greenbuls" of the genera '' Bernieria'' and '' Xanthomixis'' are actually Malagasy warblers. To recognize this, they are also called bernieria and tetrakas rather than greenbuls. Likewise, the golden greenbul is not a typical greenbul, but apparently the representative of a distinct and ancient lineage of bulbuls, which might include the black-collared bulbul. A few species within some of the genera in this group are called brownbuls or leafloves. * Genus '' Phyllastrephus'' ** Grey-olive greenbul (''Phyllastrephus cerviniventris'') ** Pale-olive greenbul (''Phyllastrephus fulviventris'') ** Baumann's olive greenbul (''Phyllastrephus baumanni'') ** Toro olive greenbul (''Phyllastrephus hypochloris'') ** Sassi's olive greenbul (''Phyllastrephus lorenzi'') ** Fische ...

Pycnonotidae
The bulbuls are members of a family, Pycnonotidae, of medium-sized passerine songbirds, which also includes greenbuls, brownbuls, leafloves, and 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 160 species in 32 genera. While different species are found in a wide range of habitats, the African species are predominantly found in rainforest, whereas Asian bulbuls are predominantly found in more open areas. Taxonomy The family Pycnonotidae was introduced by the English zoologist George Robert Gray in 1840 as a subfamily Pycnonotinae of the thrush family Turdidae. The Arabic word ''bulbul'' (بلبل) is sometimes used to refer to the "nightingale" as well as the bulbul, but the English word ''bulbul'' refers to the birds discussed in this article.

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...
