摘要

研究了2005年和2006年连续两个冬季在市政海滩上进行的疣雀天鹅时间活动预算研究。在活动模式上，年与年之间的主要差异是，2006年成年天鹅的最低进食时间减少，休息时间减少，活动时间增加。今年气温较低，同时由于担心禽流感，人类提供的面包也减少了。尽管2006年的能量消耗较高，但静音天鹅并没有增加总摄食时间，可能是因为它们仍然满足代谢需求。2006年，攻击性攻击的数量(主要是成年人对青少年的攻击)有所增加。

Behaviour of Mute Swans Cygnus olor wintering at a municipal beach in Gdynia, Poland

Mute Swan time-activity budget was studied on a municipal beach in two consecutive winter seasons, 2005 and 2006. The major difference between years in activity pattern was that adult swans decreased minimum feeding time, rested less and moved more in 2006. This year air temperatures were lower at the same time as humans provided less bread due to avian influenza fear. Despite higher energy expenditure in 2006, Mute Swans did not increase the total feeding time, probably because they still met metabolic demands. In 2006 the amount of aggressive attacks (mostly by adults on juveniles) increased.
