Abstract

The Australian zebra finch is an arid-adapted passerine with high hygric demands, that is projected to be at risk from increasing temperature and aridity throughout its distribution by the end of the century. We examine here how individual zebra finches modify their visits to water in response to the climatic conditions of ambient temperature, relative humidity, rainfall, wind speed and day length over a two-month period during an Austral summer drought in arid central Australia. Visits to water by individual zebra finches increased with increasing ambient temperature and day length, and decreased with increasing relative humidity, wind speed and rainfall. These findings are the most comprehensive data for the pattern of visits to water by individual wild birds globally and highlight the importance of regular drinking by individual finches to maintain water balance and thermoregulation. Our data highlight the importance of water availability for birds in the arid zone in a warming climate.

温度、湿度和风对澳洲斑胸草雀每日访水的影响
澳大利亚斑胸草雀是一种适应干旱的雀鸟,对水分的需求很高,预计到本世纪末,其分布地区将面临温度升高和干旱的风险。在这里,我们研究了在澳大利亚中部干旱的夏季干旱的两个月期间,斑胸草雀如何根据环境温度、相对湿度、降雨量、风速和白天长度等气候条件来改变它们对水的访问。斑胸草雀的取水次数随环境温度和日照长度的增加而增加,随相对湿度、风速和降雨量的增加而减少。这些发现是全球野生鸟类个体取水模式的最全面数据,并强调了鸟类个体定期饮水对维持水分平衡和体温调节的重要性。我们的数据强调了在气候变暖的干旱地区,水的可用性对鸟类的重要性。
