    With reference to migratory birds and flyways consider the following ...
    Statement 1 is correct.IN V formation each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired.
    Statement 2 is incorrect. Many different species share broadly similar routes, which have been loosely split
    into eight major flyways. These flyways are like bird super-highways across the sky.
    Statement 3 is incorrect. The majority of birds migrate from northern breeding areas to southern wintering grounds. However few birds breed in southern parts of Africa and migrate to northern wintering grounds, or horizontally, to enjoy the milder coastal climates in winter. Other birds reside on lowlands during the winter months and move up a mountain for the summer.
    Statement 4 is correct. Some bird species can detect polarized light, which many migrating birds may use for navigation at night. They are also able to orientate by the sun during the day, by the stars at night, and by the geomagnetic field at any time.

    With reference to migratory birds and flyways consider the following ...
    Explanation:

    1. V Formation:
    - While flying in a V formation, each bird flies slightly above the bird in front of it. This formation helps reduce air resistance for the birds flying behind the leader, making the journey more efficient.

    2. Different Routes:
    - Each group of migratory birds follows a specific route during migration known as a flyway. There are several flyways around the world, and birds within the same species typically follow the same route each year.

    3. Migration Patterns:
    - Not all birds migrate from northern breeding areas to southern wintering grounds. Some species have different migration patterns, such as altitudinal migration or short-distance migration within their breeding range.

    4. Navigation Techniques:
    - Some bird species are known to detect polarized light, which they use for navigation at night. This ability helps them orient themselves during their long migratory journeys, especially when flying over vast bodies of water or unfamiliar terrain.
    Therefore, the correct answer is option C (1 and 4 only), as the statement about different migration routes (2) and the direction of migration (3) are not universally true for all migratory bird species.
