Question

What will happen if the migration of migratory birds is checked by creating a barrier?

Answer 1

Explanation:

Why do birds migrate? ... Birds that nest in the Northern Hemisphere tend to migrate northward in the spring to take advantage of burgeoning insect populations, budding plants and an abundance of nesting locations. As winter approaches and the availability of insects and other food drops, the birds move south again

We expect that migration routes are influenced by ecological barriers because of the extra cost they add to migration. Traversing a barrier requires an extra energy and safety cost resulting from the carrying of heavy fuel loads

Answer 2

If the migration of birds is stopped by putting up barriers, bird lives would be lost as they cannot reach their designated places for food and shelter and the land where the birds migrate would lose their ecological balance.  

Explanation:

• The migration of birds is important for both the birds as well as the land in which they are migration.
• If barriers are put up and the migration is stopped then the area where they would have otherwise migrated would not receive the birds and its ecological balance would be disturbed.
• For the birds, migration is important as they seek respite from the cold weather and move to other places for food and shelter. They would not receive such.
