Introduction

Introduction

Migration is the yearly, seasonal journey undertaken by many species of birds.

During this journey, birds cover distances of many kilometres. The most common types of migration are those carried out by birds in

the spring and the autumn. In the autumn, they travel from breeding grounds in the north to

wintering grounds in the south, and vice versa in the spring.
