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 ...
Birds regulate the airflow through the syrinx with muscles—M. syringealis dorsalis and M. tracheobronchialis dorsalis—that control the medial and lateral labia in the syrinx, whose action may close off airflow. [2] Song may, hence, be produced unilaterally through one side of the syrinx when the labia are closed in the opposite side.
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).
Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
The Caroline reed warbler or Caroline Islands reed warbler (Acrocephalus syrinx) is a species of Old World warbler in the family Acrocephalidae. It is found only on the Caroline Islands in Micronesia .
Based on specimens sent from New South Wales to England, Major-General Thomas Davies illustrated and described this species as the "superb lyrebird", which he called Menura superba, in a presentation to the Linnean Society of London on 4 November 1800, but his work was not published until 1802; [5] in the intervening time period, however, the species was described and named Menura ...

The buttonquails are a group of small terrestrial birds. The smallest species is the quail-plover, the only species in the genus Ortyxelos, which is 10 cm (3.9 in) in length and weighs only 20 g (0.71 oz). The buttonquails in the genus Turnix range from 12 to 23 cm (4.7–9.1 in) in length and weigh between 30 and 130 g (1.1–4.6 oz).
