野生动物长大后的行为是怎样的？利用GPS和加速度记录仪对已知年龄的黑嘴鸥的觅食行为进行了研究。我们发现，年长的海鸥降低了它们的平均飞行速度，并且倾向于捕食陆地上的猎物，而不是海上的猎物。然而，海鸥的繁殖性能并没有随着年龄的变化。因此，老年海鸥可能会经历衰老，但优化其觅食行为与他们的年龄，以保持繁殖性能。
How do wild animals behave as they get older? We investigated the foraging behavior of black-tailed gulls (Larus crassirostris) of known age using GPS and acceleration loggers. We found that the older gulls reduced their mean flight speed and tended to feed on prey on land rather than on prey at sea. However, breeding performance of gulls did not change with age. Therefore, older gulls might experience senescence, but optimize their foraging behavior in relation to their age to maintain breeding performance.
