Which statement about the homing behavior of pigeons is true?

The sun synchronizes a pigeon's circadian rhythm and controls the bird's perceived orientation during navigation.

Homing pigeons depend on their ability to see objects with high resolution in order to navigate.

If a homing pigeon is displaced to a location with no familiar landmarks, it will fly in random directions to find home.

Homing pigeons rely completely on external cues for navigating their flight path.

If you phase-shift a bird’s circadian rhythm by 12 hours and then release the bird to find home, the bird will

orient toward home.

orient off course by 180 degrees.

orient off course by 90 degrees to the left of home direction.

orient off course by 90 degrees to the right of home direction.

If you put darkened contact lenses on a bird, the bird will

be able to fly directly home.

fly in random directions, but will be able to find its way home.

fly a path that is consistently off course by 60 degrees.

fail to navigate any path.
