The correct answer is: a) Migratory birds.
Wildlife corridors are important for the conservation of migratory birds because they provide a safe and continuous path for birds to travel between their breeding and wintering grounds. Without wildlife corridors, birds would have to fly over developed areas, which would put them at risk of being hit by cars or buildings. Wildlife corridors also provide birds with a place to rest and refuel during their long migrations.
Large mammals, aquatic species, and insects can also benefit from wildlife corridors, but they are not as reliant on them as migratory birds. Large mammals can often find suitable habitat in developed areas, and aquatic species can often find suitable habitat in rivers and streams. Insects, on the other hand, can often find suitable habitat in gardens and parks. However, all of these species can benefit from wildlife corridors, as they provide a safe and continuous path for them to travel between different areas.
In conclusion, wildlife corridors are important for the conservation of migratory birds because they provide a safe and continuous path for birds to travel between their breeding and wintering grounds. Without wildlife corridors, birds would have to fly over developed areas, which would put them at risk of being hit by cars or buildings. Wildlife corridors also provide birds with a place to rest and refuel during their long migrations.
