Question

migratory birds-tracing their flight.

explain in brief​

Answer 1

Answer:

Many bird populations migrate long distances along a flyway. The most common pattern involves flying north in the spring to breed in the temperate or Arctic summer and returning in the autumn to wintering grounds in warmer regions to the south.

Answer 2

Answer:

Birds can get compass information from the sun, the stars, and by sensing the earth's magnetic field. They also get information from the position of the setting sun and from landmarks seen during the day. There's even evidence that sense of smell plays a role for many migratory birds.
