- One possibility is that birds have a general, patchy map of key areas like their home range. It is also possible that over time and with enough interaction with the same landscape features, birds have a more "Google Maps" sense of direction. This means that they know exactly how one landscape feature is connected to the next one.

How do the birds find their way home? Decades of studies with frosted lenses, magnetic coils or scent deprivation show they use pretty much every clue available.

It is thought that birds can use both the beak magnetite and the eye sensors to travel long distances over areas that do not have many landmarks, such as the ocean. In humans, deposits of magnetite have been found in bones in our noses.
Birds use a combination of fine-tuned senses, learning, memory, and celestial and geographical clues to orientate themselves and navigate during migration. Some birds use the position of the Sun and stars as a reference, while others can detect and navigate by the Earth’s magnetic field.

One of the simplest ways a bird can make sure it's on the right track — at least while migrating over land on a clear day — is to watch for familiar landmarks below. Some ornithologists believe that day-migrating birds keep an eye out for features such as rivers and mountain ranges, using them to plot a course. There's even evidence that night-migr...
Not all birds have a great sense of smell — and if you migrate at night (as many songbirds do), landmarks might not help you much, either. When this is the case, it's time to turn to celestial navigation. In the 1960s, a father-and-son scientist team studying bird migration, John and Stephen Emlen, invented a clever method of studying whether birds...
It's not that hard to imagine finding your way by following a river, or the North Star, or even your nose. After all, we humans share the senses of sight and smell with birds. But bird migration also seems to rely on a sixth sense that we lack: the ability to feel Earth's magnetic field. Experiments to test this ability by manipulating the magnetic...
Regardless of how birds find their way — via landmarks, smell, the sun and stars, or a mysterious quantum-physics-based ability to sense magnetic fields — their journeys are inspiring. And to keep making them year after year, they need our help. In less than a single human lifetime, 2.9 billion breeding adult birds have been lost from the United St...
Apr 1, 2008 · When the fall migration period started, the birds were released into a special cage inside the planetarium. Group A was placed in the planetarium under a normal fixed sky. The birds oriented themselves in random directions, showing no ability to recognize a southerly migration direction.
