noun (plural syrinxes)
2 Ornithology The lower larynx or voice organ in birds, situated at or near the junction of the trachea and bronchi and well developed in songbirds.
- They have a tracheobronchial syrinx with one pair of intrinsic muscles and modified bronchial and tracheal rings.
- But the physical part of the syrinx in small songbirds is kind of similar from one bird to the next.
- The muscles involved in the control of respiration, the syrinx, and movements of the beak are used during song, and all muscular activity requires energy.
- Example sentences
- Complex learned vocalizations have evolved in three different groups (parrots, hummingbirds, and oscines), despite syringeal differences among groups.
- Past workers have hypothesized a close association between Myiobius and Onychorhynchus based on these syringeal and plumage characters.
- Air is pushed out of the bird's lungs and through the syringeal muscles, which the bird can squeeze almost shut until they vibrate like a trumpeter's lips.
Early 17th century: via Latin from Greek surinx 'pipe, channel'.
