Red deer Cervus elaphus In red deer, calls differ strongly between subspecies
This large old stag of Norvegian subspecies (C. e. elaphus) is already so lazy that even does not want to stand up, and produces its rutting roars when lying under the tree
This stag of Middle-European subspecies (C. e. hippelaphus) has no competitors during the rut, but nevertheless he roar and chases hinds actively, considering zoo visitors his rivals
Bugles of Canadian wapiti (C. e. canadensis) stag sound similarly to car sirens and radiate far over the zoo during the rut
Roars of Spanish red deer stags (C.e. hispanicus) sound higher by ear compared to males of other European subspecies of red, but still much lower than the siren-like bugles of Canadian wapiti
Bugles of Lesser wapiti stag (C. e. nannodes) are very hoarse compared to the large Canadian wapiti
Siberian wapiti (C.e. sibiricus) is closely related to the Canadian wapiti; probably this is the reason because their rutting bugles are so similar
Canadian wapiti hind (C. e. canadensis) is calling her high-pitched calls at arousal evoked by rutting bugles of a male in neighboring enclosure and anticipation of feeding
A few hinds of Spanish red deer (C.e. hispanicus) are emitting their rather low-pitched compared to wapiti hinds' calls when wishing to rejoin with their calves separated temporally in the neighboring enclosure
A natural bout of three rutting calls of an Spanish red deer (C.e. hispanicus) stag with source-filter coupling in third call. At the moment of transition from normal phonation to source-filter coupling mode the roaring sound turns to siren-like sound.
Calls of the Lesser wapiti hinds (C. e. nannodes) are dissonant, consistently to the hoarse sounding stags of this subspecies
A hind of Siberian wapiti (C.e. sibiricus) is walking to and fro in enclosure and call loudly a series of high-pitched calls, anticipating the feeding
Females of the Siberian wapiti (C.e. sibiricus) call for their young with loud oral contact calls
Sequence of loud oral barks – female alarm calls toward a spotted researcher
Calls of a Siberian wapiti (C.e. sibiricus) calf, which approaches a human, supposing that this is its mother

Professional singer imitates the rarely occurring in rutting calls of Iberian stags siren-like acoustic effect, which is produced in the source-filter coupling mode
Roars of a stag of Norvegian subspecies (C. e. elaphus) during the rut; it is well-visible how the larynx is descending throughout a call, to lower the perceived voice pitch and to exaggerate the apparent body size of the stag
A stag of Middle-European subspecies (C. e. hippelaphus) roars very actively during the rut
The male wapiti (C. e. canadensis) is so aggressive during the rut, that his antlers are sawed out to prevent wounding his own hinds and calves, when he chases them
A relatively small stag of Lesser wapiti (C. e. nannodes) should compete vocally during the rut with a very large Canadian wapiti in neighboring enclosure, but he makes it successfully |
