Time activity patterns of wintering Mute Swans were studied over three seasons in and near Cracov using the focal bird sampling method. In the city the swans were fed by people, while outside the city the birds were not fed by people. Rural Mute Swans spent 48.1% of the daytime eating, while urban swans fed only 4.6% and begged 8.7% of the time. Urban birds spent more time swimming and loafing (28.3 and 36.1%, respectively) than rural birds (10.2 and 18.4%). The daily activity pattern for rural swans was generally bimodal with early morning and late afternoon peaks in feeding, and a mid-day resting period. In contrast, the swans in Cracov did not show any cycle in diurnal feeding activity. There were differences in the frequencies of aggressive behaviour between urban and rural swans. In the city aggression occurred much more often. The behaviour of urban swans during the night was very similar to nocturnal activities of rural swans. The activity pattern of swans wintering in Cracov is probably mainly due to adaptations to the feeding by people.
Background. Changes in the economic and political system that took place in Poland in recent decades had a significant impact on lifestyles of different social groups, especially in youngsters as vulnerable and open to all novelty and changes. Objective. The aim of this study was to evaluate the healthy or non-healthy behaviours including physical activity, diet, time devoted for sleeping, leisure, stress and the use of drugs by students of four universities in Wroclaw. Material and Methods. The study involved 604 students (305 women and 299 men) from four universities in Wroclaw: University of Wroclaw - 25.0%, Wroclaw University of Technology - 24.5%, University School of Physical Education (AWF) - 25.2% and Wroclaw Medical University - 25.3%. A questionnaire developed for this study was used. The questions were both open and closed, one or multiple answers could be matched. The questions related to: physical activity, nutrition, time devoted for sleeping, leisure, stress and stimulants. Results. On the basis of the results it was found that students mostly reported an average level of physical activity. The highest level of physical activity was presented by students of the University School of Physical Education and the lowest by students of the University of Wroclaw. Just one in ten students consumed meals on a regular basis, including one in five studying in the AWF. Almost half of the respondents (48.7%) spent 5-7 hours sleeping. Every tenth student slept less than five hours. Most respondents preferred passive forms of recreation, only one in three practiced sports in their spare time (usually students of the AWF). Every fourth student declared smoking, and more than 90% consumed alcohol. Conclusions. Lifestyle of majority of the students surveyed did not follow the recommendations of preventive care. The need for more efficient education of students is obvious, which will lead to the future positive changes in their lifestyle, reducing the risk of lifestyle diseases.
