Marine environment
Species linked to coastal wetlands and the littoral above all. It avoids inland wetlands. Preference for shallow waters with sandy bottoms such as mouths, salt ponds and marshes.
Bird present in the province only during its migratory passages. The Common Tern travels thousands of kilometres from its breeding grounds in northern Europe to equatorial Africa to spend the winter. In the Iberian Peninsula it only breeds in the Atlantic coast and exceptionally in some Mediterranean locations. This seabird nests in colonies and on the ground. One annual laying of 2 to 3 eggs at the end of March or in April. It feeds on small fish and aquatic crustaceans caught with fast plunges in which the tern often gets to dive completely
Frequent species in the province. It is possible to observe it especially in the coast, fishing both in river mouths and in the beach. The presence of isolated individuals or flocks of a few specimens is common. The mouth of the Guadalhorce is one of its most frequent resting grounds on the coast of Malaga.
Its Latin name, hirundo, makes reference to its similarity in morphology and way of flying with swallows. They share a forked tail and narrow wings in flight. For this reason terns are popularly known as "sea swallows".
