Why does bird migrate?

Answer 1

They migrate because of different weather conditions and food supplies.

Migratory birds generally fly somewhere to breed, raise their chicks and then fly back.

Some fly hundreds (or thousands) of miles. This is generally driven by the need for food and mating space.

Answer 2

Migration is a fight for survival. It is undertaken in order to ensure that the animals have enough food to eat. For example, insect-eating birds like flycatchers go north in the summer at the same time that mosquitoes are hatching, and go south again when it gets cold out and the food supply becomes less. If all the birds stayed in a warm place year round, they'd eat all the food in that spot and many of the birds would die off; likewise, if most of the birds stayed in the north in the winter, they would run out of food. Moving around helps them find the constant supply of food they need.

Answer 3

Birds' travel from place to place is called "migration". When it gets colder the birds move to where it's warmer and/or food is more plentiful. So every fall birds migrate down south like in the warmer area's like Arizona.

Answer 4

They migrate to more favorable climates where they reproduce or feed, in most cases it is away from the cold in winter, and back again in the summer.

There is very little to eat in a snowy climate.

Answer 5

Basically, birds don't like the cold, so they move somewhere warmer.
