随着全球陆地表面以惊人的速度转变为城市区域，了解个体对城市化的反应是行为生态学的关键关注点。作为鸟类父母照料的重要组成部分，孵化的成鸟面临着在为发育中的胚胎保持最佳热环境与满足自身能量需求之间的权衡。城市栖息地在生物和非生物方面与农村栖息地不同，即在食物可获得性、捕食者组成和热环境方面。因此，城市鸟类可能面临不同于自然鸟类的孵化挑战。在12天的时间里，我们用温度记录仪测量了农村和城市家燕的孵化行为。我们发现，与农村女性相比，城市女性孵化的次数更多，持续时间更短，每天孵化的总时间更少。这一结果可能会提供城市白鹭行为变化的证据，这对父母养育的演变有一定的影响。我们的发现有助于我们理解城市生活所需的行为特征，以及可能驱动城市适应的环境压力。
As global land surfaces are being converted to urban areas at an alarming rate, understanding how individuals respond to urbanization is a key focus for behavioral ecology. As a critical component of avian parental care, incubating adults face a tradeoff between maintaining an optimal thermal environment for the developing embryos while meeting their own energetic demands. Urban habitats are biotically and abiotically different from their rural counterparts, i.e., in food availability, predator compositions, and the thermal environment. Therefore, urban birds may face different incubation challenges than their natural counterparts. We measured incubation behavior of rural and urban house wrens, Troglodytes aedon, with temperature loggers throughout the 12-day period. We found that urban females had more incubation bouts of shorter duration and spent less total time incubating per day than rural females. Results could provide evidence of behavioral shifts of wrens in cities, which have implications for the evolution of parental care. Our findings contribute to our understanding of the behavioral traits needed for city life and possible environmental pressures driving urban adaptations.
