Bulbuls are medium-sized songbirds. Some are colourful with yellow, red or orange vents, cheeks, throats or supercilia, but most are drab, with uniform olive-brown to black plumage. Some species have distinct crests. Common bulbul, Pycnonotus barbatus; Red-whiskered bulbul, Pycnonotus jocosus (I) White-eared bulbul, Pycnonotus leucotis ...
The order is divided into three suborders, Tyranni (non-singing, Americas), Passeri (songbirds), and the basal New Zealand wrens. [9] Oscines have the best control of their syrinx muscles among birds, producing a wide range of songs and other vocalizations, though some of them, such as the crows , do not sound musical to human beings.
The brown songlark (Cincloramphus cruralis), also Australian songlark, is a small passerine bird found throughout much of Australia. A member of the family Locustellidae , this species is notable for sexual size dimorphism , among the most pronounced in any bird. [ 2 ]

As an example, the great tit, a European songbird, uses such a signal to call on nearby birds to harass a perched bird of prey, such as an owl. This call occurs in the 4.5kHz range, [66] and carries over long distances. However, when such prey species are in flight, they employ an alarm signal in the 7–8 kHz range.
Most species are rather plain, with various hues of brown, gray and white commonplace, often providing some degree of presumed camouflage.Obvious exceptions include the bright red vermilion flycatcher, blue, black, white and yellow many-colored rush-tyrant and some species of tody-flycatchers or tyrants, which are often yellow, black, white and/or rufous, from the Todirostrum, Hemitriccus and ...
