“…The male syrinx is larger in many species (Häcker 1900;Wade and Buhlman 2000;Veney and Wade 2004). Furthermore, sexual differences occur in both size of the vocal apparatus and vocalizations in various non-passerines, including Anseriformes (Warner 1971;Lockner and Youngren 1976;Lalatta-Costerbosa et al 1990), Columbiformes (Ballintijn and Ten Cate 1997), Galliformes (Bottino et al 2006); Ralliformes (Gullion 1950), and Turniciformes (Balthazart et al 1983).…”

Species and sexual differences in vocalizations and the vocal tract are widespread. We studied the vocal tract of Common (Uria aalge) and Thick-billed (U. lomvia) Murres. We predicted anatomical or allometric differences in adults between species and sexes due to vocal differences related to social behavior (Common Murres nest at higher densities; males are the more aggressive sex, etc.). The vocal tract was anatomically simple and similar between species and sexes. The trachea was mainly cartilage, but the posteriormost 4-6 tracheal rings were calcified and fused as the tympanum, as part of the syrinx. The syrinx included the (unfused) first bronchial semirings, which were enlarged and calcified beneath the insertion of M. tracheolateralis. Weak bilateral asymmetry (right side larger) occurred in widths of M. tracheolateralis and M. sternotrachealis. The trachea was *10% longer in Common Murres; the tympanum and M. sternotrachealis width were relatively larger in Thick-billed Murres. Vocaltract morphology and size did not differ between the sexes in either species. In allometric analyses on adults, isometry characterized (1) tympanum size in relation to head + bill length, and to humerus length (respectively), in Thickbilled Murres, and (2) M. sternotrachealis width in relation to tarsometatarsal length in both species. Comparative field studies on species and sexes are needed to clarify the functional significance of our findings in relation to vocalization.

“…Previous studies with syrinx in orange‐winged parrot (Nottebohm, 1976), Japanese quail (Çevik‐Demirkan et al, 2007), common murre and thick‐billed murre (Miller et al, 2008), also did not observe sexual dimorphism. The opposite was observed in studies carried out with guinea fowl (Bottino et al, 2006), where males have a higher number of cranial and intermediate cartilages than females, thus favouring sound amplification. The Mallard duck syrinx is characterized by a remarkable sexual dimorphism.…”

“…The red‐winged tinamou and red‐legged seriema syringes were of the tracheobronchial type, as well as in guinea fowl (Bottino et al, 2006), cinnamon‐tailed buzzard (Kabak et al, 2007), goose (Onuk et al, 2010), greater rhea (Picasso & Carril, 2013), chukar partridge (Erdögan et al, 2015), turkey (Ragab et al, 2016) and Mallard duck (Mohamed, 2017). The white‐eyed parakeet syrinx, in turn, was of the tracheal type, as well as that of other parrots (Gaunt & Gaunt, 1985).…”

The aim of this study was to describe the morphology of the trachea and syrinx at macroscopic and light microscopy levels of three species of birds from different orders that inhabit the Brazilian cerrado. For that, five adult specimens (three males and two females of each species) of white‐eyed parakeet (Psittacara leucophthalmus), red‐winged tinamou (Rhynchotus rufescens) and red‐legged seriema (Cariama cristata) were used. The trachea and syrinx of the birds were collected and destined for anatomical and histological studies. The trachea of the studied birds presented an elongated path and originated in the larynx and extended caudally to the syrinx. No sexual dimorphism was observed in the syrinx of the studied species, probably because it is associated with their song, which is very similar between males and females of these species. The findings of this study allowed us to classify the syrinx as tracheal in the white‐eyed parakeet and tracheobronchial in the red‐winged tinamou and red‐legged seriema. In general, the morphological features of the trachea and syrinx were similar to those described for other species of birds, such as the presence of intrinsic and extrinsic syringeal muscles, and the lateral and medial tympaniform membranes, which would represent important anatomical structures in sound production through vibration during expiration and eventual inspiration. The morphological structure of the syrinx in the three avian species of the Brazilian cerrado is consistent with the ability of these avian species to perform a potential vocalization, especially the red‐legged seriema that emits characteristic sounds very loud and can carry several kilometres.
