“SYRINX” на російській мові

They have a tracheobronchial syrinx with one pair of intrinsic muscles and modified bronchial and tracheal rings.

They have small, rudimentary clavicles, a small procoracoid process, no syrinx , and reduced caeca.

But the physical part of the syrinx in small songbirds is kind of similar from one bird to the next.

That is reflected in the fact that two of the relevant taxa, parrots and songbirds, use different parts of the syrinx to make their vocal signals and different parts of their brains to control sound production.

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.
