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.

迁徙鸟类穿越边界，在大型地理尺度（300-8000公里）上在各个位置繁殖，换羽和冬季。他们以每年大约同一时间发生的迁移活动而闻名，这可以通过外源性（温度，食物丰度等）和内源性的计时机制的影响来解释。在拟议的研究计划中，我的目的是描述海鸭的年度周期，并了解各种生物阶段如何按时间顺序和精力整合到繁殖成功方面。我将使用微型数据记录系统来监视野生和圈养个体的生理和行为参数，以确定内源性时钟的存在作为计时机制。重要的是要了解迁徙鸟类如何根据环境波动来调整其季节性活动，因为它可以揭示它们可能适应气候变化的策略。
