It also utters a scolding call, transcribed as ch-churr or churr-churr, and a two-syllabled zitting call. Around nesting time, the female utters a courtship or food-begging call, composed of a long note with a deeper staccato note at the end. It does not resemble any other species within its range. The similar eastern yellow robin is only found in the eastern states.

The Golden nightjar's song is low pitched churr which may last quite a long time and is delivered at dawn and dusk from the ground.

All subspecies, with the exception of atriceps, have a quiet rapid monotone kee'r'r-ker'r-ke'r'r" call, whereas atriceps has been described as more of a churr ... grr'r'r'r'l".

White wing patches are prominent in flight. The dark tail has white bars on the central tail feathers. They range from in length. This woodpecker's voice is a rolling churr sound.

This is a common and popular European garden bird, due to its perky acrobatic performances when feeding on nuts or suet. It swings beneath the holder, calling "tee, tee, tee" or a scolding "churr".

Competitive lek singing can occupy half of the daylight hours to attract females. The female selects the best lek singer to mate. The song consists of high pitched squeaky of chink churr and shree sounds. The flight call is a high sweep.

The rufous-tailed palm thrush is shy, usually found in pairs or small groups. It gives the call churr when alarmed. Its song, usually given at dawn or dusk, is a series of loud and melodious whistles, mixed with babbling and chattering. Pairs of birds sometimes duet.

A low "churr" is also used to communicate with nearby groups. Hands are normally pentadactylous, with four digits and a rudimentary thumb. Fingers have large broad soft pads, where the inner pad is expanded for gripping while moving through branches. Feet are also comprised with soft pads with both fore and hind limbs possessing long, sharp claws.

The metallic song of the bird includes a series of clicks followed by five or six notes that end abruptly. The metallic song consists of short clicks followed by five or six notes resembling that of the Spot-breasted fantail. Alarm calls include churr and clicking notes. It is a wary bird and is easily observed in small gardens too.

The territorial song, given by both sexes, seems to vary geographically from a harsher chattering song in the west to a more melodious. pleasant and repetitive "twee-churr-urr-urr" in Cyrenaica. The courtship song sounds like an old fashioned boiling kettle, a long warbling whistle rising in pitch given in duet by both sexes. The alarm and contact calls are typically chat like harsh clicks.

They can be difficult to observe in the dense vegetation they prefer, but like other babblers, these are noisy birds, and their characteristic rattling churr alarm calls are often the best indication that these birds are present. They often join mixed-species foraging flocks. The breeding season is May to July. This babbler builds its nest low down in a bush, the nest being a ball of leaves, often of bamboo.

The aerial predator alarm call is a series of high-pitched, slurred whistling notes. The broad-frequency alarm calls are a series of 'churr' notes, low-pitched and harsh, occurring at low and high levels of intensity. The narrow-band call is used in situations where the bird signals the presence of a predator and restricts information about its own location, while the broad-band alarm is used to attract attention, and can initiate mobbing behaviour. These churring calls vary between individuals, and laboratory tests show that noisy miners can distinguish calls by different birds.

The rippling preep and whistled sweeeooo calls of the Alpine chough are quite different from the more typically crow-like chee-ow vocalisations of the jackdaw and the red-billed chough. It also has a rolling churr alarm call, and a variety of quiet warbles and squeaks given by resting or feeding birds. In a study of chough calls throughout the Palearctic region it was found that call frequencies in the Alpine chough showed an inverse relationship between body size and frequency, being higher-pitched in smaller-bodied populations.

Males will sing a three-part song composed of two short whistles: a wheerreep followed by a higher-pitched whee, and a soft low churr. This song is meant to be heard by a mate at short distances, indicating periods of low disturbance and stress typically intensifying just before dawn. It is appropriately named "dawn song" (or twilight song). In addition to the dawn song, great crested flycatcher also produce various calls, a series of fast ascending huit, huit, huit is given in moments of stress or excitement during interactions of between neighbours.
