ABSTRACT



The investigations comprised the upper respiratory tract in 100 adult ducks: 57 mallard Anas platyrhynchos (30 males and 27 females) and 43 scaup Aythya marila (26 males and 17 females). The work aimed at the anatomical comparison of the organs constituting the upper respiratory tract. Had the sex and age of the investigated birds been determined, the specimens of the upper respiratory tract, preserved in 4% formaldehyde solution, were described morphoanatomically including the larynx, trachea, syrinx and bronchi primarii. The interspecific comparisons of males and females of both species indicated a considerable divergence in the shape, size and structure of the syrinx. They refer, among others, to an extensive membrane, a constituent of the syrinx tympanum in the drakes of scaup which was absent in mallard.

Key words: mallard (Anas platyrhynchos), scaup (Aythya marila), larynx, trachea, syrinx, bronchi primarii.
