Earth's magnetic field

Many birds use Earth's magnetic field to navigate.

using celestial cues from the sun and stars

We now know that birds navigate using celestial cues from the sun and stars, the earth’s magnetic field, and inbuilt genetic “mental maps”.

using the stars

Since birds navigate using stars, artificial nighttime light attracts and disorients them.

using earth's magnetic field

We know that birds can navigate using earth's magnetic field, but no one really knows how.

by the Earth's magnetic field

We know that birds navigate by the Earth's magnetic field - if the magnetic field changes, birds may fall.

using stars

The birds navigate using stars and features on land.

by the stars or by changes in the earth's magnetic field

The birds may navigate by the stars or by changes in the earth's magnetic field.

by the light from the moon and stars

Birds typically navigate by the light of the moon and stars, but if they find themselves in an artificially lit environment, they may get confused and often have difficulty leaving difficulty , causing them to have collisions.

and features on land

The birds navigate using stars and features on land.

using both a genetically inherited sense of direction and a magnetic sense that enables them to use the Earth's magnetic field lines to work out their location

During migration, birds navigate using both a genetically inherited sense of direction and a magnetic sense that enables them to use the Earth's magnetic field lines to work out their location.

a variety of methods

Scientists have discovered that birds use a variety of methods to find their way around, taking account of the orientation of the sun and stars as well as local visual and olfactory cues.

by a variety of means including sensing the Earth's magnetic field, visual cues including the stars

Birds can navigate by a variety of means including sensing the Earth's magnetic field, visual cues including the stars, and even sounds.

during migration in part by sensing the Earth's magnetic field

Birds navigate during migration in part by sensing the Earth's magnetic field, and some scientists have speculated that artificial light may disrupt a light-sensitive internal magnetic compass.

the Earth's magnetic field and the Earth's magnetic field's thanks to a substance in the bird's eyes that allow them to see magnetic fields

It turns out that birds really do have a sixth sense, scientists have finally discovered how birds navigate the Earth's magnetic field and the Earth's magnetic field's thanks to a substance in the bird's eyes that allow them to see magnetic fields.

using cues from the sun in the day

Birds will navigate using cues from the sun in the day and stars at night.

by sensing Earth's magnetic field

Migrating birds navigate by sensing Earth's magnetic field, but the exact mechanisms at work are unclear.
