Seabirds Get Jet Lagged
New study reveals Manx shearwaters experience jet lag during long flights over the North Atlantic, affecting their navigation
Seabirds like Manx shearwaters experience jet lag during their long flights over the North Atlantic, which can disrupt their navigation. This phenomenon occurs when the birds cross multiple time zones, causing a mismatch between their internal clock and the external environment. Manx shearwaters are medium-sized birds, about the same size as a pigeon, with long wings and a distinctive black and white coloration. They are closely related to albatross and are known for their impressive migration patterns.
What is Jet Lag in Seabirds?
Jet lag in seabirds is similar to the condition experienced by humans, where the body's internal clock is disrupted due to rapid travel across time zones. This can cause a range of problems, including fatigue, disorientation, and difficulty navigating. In the case of Manx shearwaters, their navigation system is based on the position of the Sun, which can be affected by the jet lag.
How Do Seabirds Navigate?
Seabirds like Manx shearwaters use a variety of cues to navigate, including the position of the Sun, the Earth's magnetic field, and visual landmarks. However, when they experience jet lag, their ability to navigate can be impaired. This is because their internal clock is out of sync with the external environment, making it difficult for them to determine their direction and location.
Comparison of Navigation Systems
| Navigation System | Description | Advantage |
|---|---|---|
| Sun navigation | Uses the position of the Sun to determine direction | Simple and effective |
| Magnetic navigation | Uses the Earth's magnetic field to determine direction | Accurate and reliable |
| Visual navigation | Uses visual landmarks to determine direction | Useful for short distances |
Frequently Asked Questions
t is the impact of jet lag on seabirds? Jet lag can have a significant impact on seabirds, disrupting their navigation and causing problems such as fatigue and disorientation. ### How do seabirds adapt to jet lag? Seabirds can adapt to jet lag by adjusting their internal clock to the new time zone, but this can take several days. ### What is the significance of the study on Manx shearwaters? The study on Manx shearwaters provides new insights into the effects of jet lag on seabirds and highlights the importance of considering the impact of time zones on bird migration patterns. ### Can humans learn from seabirds' navigation systems? Yes, humans can learn from seabirds' navigation systems, which are often more effective and efficient than human-made systems. The study on Manx shearwaters was conducted by a team of researchers from the University of Oxford, led by behavioral and sensory ecologist Patrick Lewin. The team used a combination of field observations and laboratory experiments to investigate the effects of jet lag on the birds' navigation system. The results of the study provide new insights into the biology and ecology of seabirds and highlight the importance of considering the impact of time zones on bird migration patterns. *Source: John Timmer*
