Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply birdsong ) are the bird sounds that are melodious to the human ear. In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
The common sounds the male bird makes towards a female is "woikawoikawoika", symbolizing their relationship to one another and other birds. If the call is used towards a male, it is a territorial sign. [23] The calls' pattern can be classified as flat and gradually rises into a loud noise. The call type is a chirp that drums and rattles.

An annual International Dawn Chorus Day is held on the first Sunday in May [6] when the public are encouraged to rise early to listen to bird song at organised events. The first ever was held at Moseley Bog in Birmingham, England, in 1987, organized by the Urban Wildlife Trust (now The Wildlife Trust for Birmingham and the Black Country).
The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to 88 km/h (55 mph). [3] Mourning doves are light gray and brown and generally muted in color. Males and females are similar in appearance. The species is generally monogamous, with two squabs (young) per ...
The feathers making up this disc can be adjusted to sharply focus sounds from varying distances onto the owls' asymmetrically placed ear cavities. Most birds of prey have eyes on the sides of their heads, but the stereoscopic nature of the owl's forward-facing eyes permits the greater sense of depth perception necessary for low-light hunting.
Apr. 24—CHEYENNE — Picture a lemon-breasted western meadowlark perched atop a fence post. He's singing that crystalline meadowlark song, the one that flows like water into your ears across a ...
The syrinx (from the Greek word "σύριγξ" for pan pipes) is the vocal organ of birds. Located at the base of a bird's trachea, it produces sounds without the vocal folds of mammals. [1] The sound is produced by vibrations of some or all of the membrana tympaniformis (the walls of the syrinx) and the pessulus, caused by air flowing through ...
Disrupting the birds' light and dark cycles can impact circadian rhythms, eventually harming sleep patterns. Biologist Thomas Raap conducted a study which suggested that exposure to ALAN affected the sleep behavior of Eurasian blue tits (Cyanistes caeruleus). [7] In this study, birds woke up earlier due to ALAN factors such as seasonal timekeeping.
