Many birds travel long distances every year. This process is called migration. Sometimes, birds have problems during migration. Bright lights
can confuse them. Tall towers can get in their way. Sources of food along the trip can disappear.
Many scientists want to help migrating birds. An important first step is to study migration. Scientists need to learn exactly when and where
certain birds fly. They need to count how many birds travel along these routes each year.
There are many ways to gather information about migration. Scientists watch the sky on certain days each year and count how many birds
they see. Some watch from land. Others watch from ships. On clear nights when the moon is bright, night-flying birds can be seen against the
moon. Also, scientists shine bright lights at night to help spot passing birds. Satellites in space are used to track migrating birds around the world.
Which statement would best conclude Robert's draft?
1. Scientists can track every bird that migrates.
2. Many birds migrate thousands of miles each year.
O 3. Scientists are working hard to study bird migration.
04. Some birds get lost during migration and are taken to rescue centers.
Please help :)
