The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs.

2018年10月5日 · The melodious call of many birds comes from a mysterious organ buried deep within their chests: a one-of-a-kind voice box called a syrinx. Now, scientists have concluded that this voice box evolved only once, and that it represents a rare example of …

syrinx, vocal organ of birds, located at the base of the windpipe (trachea), where the trachea divides into the bronchi (tubes that connect the trachea with the lungs).

2024年2月9日 · The size and shape of a bird’s syrinx determines the timbre, pitch, and volume of its vocalizations. Songbirds, parrots, and hummingbirds have more complex syrinxes capable of a wider range of vocalizations than birds like chickens or pigeons.

2024年5月31日 · Have you ever wondered how a bird sings? Or made some of their less melodic vocalizations, like squawks, trills, or chirps? It all happens in the syrinx, a vocal organ unique to birds. Reptiles, amphibians, and mammals, including humans, use their larynx to produce sounds.

2021年6月14日 · The syrinx, Greek for pan pipes, is the vocal organ of birds. Instead of being located at the bottom of the pharynx as in a mammal’s trachea , the syrinx is located where the trachea branches into two bronchi, each entering the lungs.

2024年5月25日 · The research team explored the genetic origins of the syrinx, analyzing its development in 14 bird species. Their findings suggest that the common ancestor of modern birds likely had a syrinx with two sound sources.

2018年9月24日 · Here, we focus on one critically understudied and undertheorized aspect of avian evolutionary novelty, the origin of the evolutionarily novel sound-producing organ of birds, the syrinx.

2022年10月24日 · Unlike crocodylians, their closest extant relatives, birds phonate with a unique vocal organ, the syrinx, which is located at the tracheobronchial junction. This location facilitated the evolution of two independent sound sources. (Modified from Kingsley et al. (2018) © PNAS.)

Birds lack vocal folds so sound is produced in the syrinx, which is the avian equivalent of the mammalian vocal cords. There is specialisation of the trachea by bifurcation. The syrinx is located at the caudal end of the trachea and at the beginning of the primary bronchi and is …
