Migratory birds cross frontiers to breed, moult and winter at various locations over large geographic scales (300-8000 km). They are well known for their migratory activity to occur at about the same time every year, which may be explained by the influence of timekeeping mechanism of exogenous (temperature, food abundance etc.) and endogenous nature. In the proposed research program, my aim is to describe the annual cycle of sea ducks and understand how the various biological phases are integrated chronologically and energetically in relation to breeding success. I will use miniature data logging systems to monitor physiological and behavioural parameters of wild and captive individuals in order to determine the presence of endogenous clocks as a timekeeping mechanism. It is important to understands how migratory birds adjust their seasonal activities in relation to environmental fluctuations as it could unravel the strategy by which they may adapt to climate change.

候鸟跨越边界，在大的地理范围（300-8000公里）的不同地点繁殖、换羽和越冬。众所周知，它们的迁徙活动发生在每年大约相同的时间，这可能是由外源（温度，食物丰富度等）的计时机制的影响解释。和内生性。在拟议的研究计划中，我的目标是描述海鸭的年度周期，并了解如何将各个生物阶段按时间顺序和精力整合到育种成功。 我将使用微型数据记录系统来监测野生和圈养个体的生理和行为参数，以确定作为计时机制的内源性时钟的存在。重要的是要了解候鸟如何根据环境波动调整其季节性活动，因为这可能会揭示它们适应气候变化的策略。
