Many birds, especially those that nest in cavities, are known to produce a snakelike hissing sound that may help deter predators at close range. [ 44 ] Some cave-dwelling species, including the oilbird [ 45 ] and swiftlets ( Collocalia and Aerodramus species), [ 46 ] use audible sound (with the majority of sonic location occurring between 2 and ...
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.

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 ...
Sonation is the sound produced by birds, using mechanisms other than the syrinx. The term sonate is described as the deliberate production of sounds, not from the throat, but rather from structures such as the bill, wings, tail, feet and body feathers, or by the use of tools. [1]
How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
During the sensory phase, birds memorize the song of a tutor animal, forming a template representation of the species-specific song. [32] The sensorimotor phase follows and may overlap with the sensory phase. During the sensorimotor phase, young birds initially produce variable, rambling versions of adult song, called subsong.
