The influence of social interactions on the foraging path of Bewick’s Swans Cygnus columbianus bewickii.
Whistling Swan (Cygnus columbianus) Science Article 3 abstract The efficiency in which high-density food patches are found is determined by the way foragers move between patches. In this study we explore the effect of social interactions on the foraging path, in particular the distance moved between patches. We studied Bewick’s Swans Cygnus columbianus bewickii that […]
The condition of Bewick’s Swans Cygnus columbianus bewickii in winter as assessed by their abdominal profiles.
Whistling Swan (Cygnus columbianus) Science Article 1 abstract An Abdominal Profile (AP) scale was developed to assess body condition of Bewick’s Swans in the field. Change in AP score for individual birds correlated significantly with change in their body mass; moreover AP was significantly correlated with condition indices that were designed to remove the potential […]
Ventilatory and circulatory responses to hyperthermia in the mute swan (Cygnus olor)
Mute Swan (Cygnus olor) Science Article 2 abstract Ventilatory parameters of mute swans were measured at thermoneutral conditions and during heat stress. Deep body temperature increased from 39-5 to 41-1 deg C. Breathing frequency increased 29 times, compared to the thermoneutral condition. Tidal volume decreased to 18 % of the pre-panting value, and the total […]
