[ 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.
The young of some birds learn to communicate vocally by social learning, imitating their parents, as well as the dominant birds of their flock.Lacking vocal cords, birds are thought to make tones and sounds using throat muscles and membranes – the syrinx in particular. [5]

European birds lack the long gray tongues on the 6th, 7th, and 8th primaries and solid black markings on the 5th and 6th primaries that are shown by American herring gulls. [11] First-winter European birds have more checkered upperparts, more streaked underparts, and a paler rump and base to the tail.
