The aim of this study was to investigate the special anatomical and topographical features of the syrinx in male adult stock ducks (Anas platyrhynchos). The syrinx of the mallard is a tracheobronchial type, consisting of a tympanum, a pessulus, medial tympaniform membranes, interanular membranes, an interbronchial ligament (bronchidesmus), and bronchosyringeal cartilage semi‐rings. Using a frozen sagittal section, it was possible to document the syringeal valve at the right lateral side of the… 
Anatomical Structure of the Syrinx in the Mallard (Anas platyrhynchos)
TLDR
It was determined that syrinx in male ducks was found to be asymmetrical and had a large expansion on the left side called bulla tympaniformis.

Birds are considered a good model for studying the phonation process, the syrinx is a vocal organ in birds. The purpose of this study is to investigate the topographical and morphological
The gross anatomy of larynx, trachae and syrinx in goose (Anser anser domesticus).
TLDR
The cartilage rings in middle parts of trachea which seem to be “H”-shaped forked and also the tympanum which is completely fused and ossified characteristic for the goose are found.

MORPHOLOGICAL STUDY OF LARYNX AND SYRINX OF BLACK FRANCOLIN ( Francolinus francolinus ) IN IRAQ
The syrinx of male and female adult black francolin was studied. Seven adult males and females weighted (300) gm to (265) gm respectively, were captured from the village of Baghdad. Macroscopic
Macroscopic study of syrinx in the common bulbul (Pycnontus barbatus) and indigenous pigeon (Columba domestica)
TLDR
The syrinx was observed ventral to the esophagus exactly on the base of heart in the common bulbul, whilst in pigeon; the syrinX was hidden by the heart.
The peculiar syrinx of Rhea americana (Greater Rhea, Palaeognathae)
TLDR
This work studied the skeletal and muscular syringeal anatomy of Greater Rhea throughout postnatal ontogeny, by using muscle staining and differential coloring of cartilage and bone techniques to contribute to the understanding of the evolution of soundproduction mechanisms in birds.
Macroanatomic Examination of the Trachea and Syrinx in Budgerigars and Canaries
TLDR
The purpose of the present study is to examine and compare the trachea and larynx caudalis of budgerigars and canaries in a macroanatomic manner and it was observed that in all species thetrachea rings were full.
Histomorphological Study of Syrinx of Black Francolin (Francolinus francolinus) in Iraq
TLDR
The syrinx of male and female adult black francolin was studied, the males had significantly narrow tympanum and right syringeal passage with thicker Syringeal labia than female and sexual dimorphism were obtained.
Anatomical, Histological, and Electron Microscopic Structures of Syrinx in Male Budgerigars (Melopsittacus undulatus)
TLDR
The electron microscopic examination revealed numerous blood capillaries surrounded by fibroblasts and numerous immune cells, including mast cells and wandering leukocytes, within the tympanum mucosa, which provides a detailed knowledge about the syrinx in male budgerigars.

The anatomy of the syrinx in passerine birds
TLDR
Variations in syringeal structure within families Corvidae (Corvus corone, C. frugilegus), Sturnidae (Sturnus vulgaris, Gracula religiosa), Turdidae (Turdus merula, Erithacus rubecula) and Paridae (Parus major, Aegithalos caudatus) are described and discussed and the significance of these findings in relation to bird sound production is discussed.
Interclavicular air sac pressures and vocalization in mallard ducks Anas platyrhynchos.
TLDR
Reducing interclavicular air sac pressures increases the harmonic complexity of the calls and the effect is most pronounced in adult females and ducklings, while opening the sac to the atmosphere reduces the intensity of calling in adults and Ducklings.
