With its rusty‐red breeding plumage complete, this red Knot (Calidris canutus) is ready for a migration from temperate intertidal wetlands to the High Arctic tundra breeding grounds. In fact, at this point the bird may feel nostalgic about its birth land, and motivated to undertake the long‐ and unpredictable journey ahead.

结成锈红色的繁殖羽毛完成后，该红色结（Calidris canutus）就可以从温带潮间带湿地迁移到北极高寒带苔原繁殖地。实际上，在这一点上，这只鸟可能会对自己的出生地怀有怀旧之情，并有动力进行漫长而又不可预测的旅程。在Dyrarflordur（冰岛）拍摄的照片，并经Jan van de Kam Wildlife Photography的许可转载。基于原始文章EMA Kok，JA Hogan和T.Piersma对https://doi.org/10.1111/eth.13036所做的关于长距离迁徙水鸟栖息地的季节性视觉偏好的实验测试。
