Renowned for its graceful aerial acrobatics and distinctive forked tail, it is a seabird that boasts an extensive range encompassing diverse coastal and marine habitats. Affectionately referred to as the ‘sea-swallow’ due to its agile flight and elegant appearance, the common tern is a master of the skies, often observed hovering effortlessly above the water before plunging into the depths with remarkable precision to catch its prey.
Nesting in large, noisy colonies, common terns exhibit a fascinating blend of elegance and pugnacity, particularly when defending their territories against intruders. Raucous swoops and aggressive displays are common responses to perceived threats, highlighting the fiercely protective nature of these seabirds when safeguarding their nesting sites and offspring.
As migratory birds, common terns undertake remarkable journeys between their breeding and wintering grounds, navigating vast distances with remarkable precision and endurance. Beginning their southward migration between late August and October, common terns embark on an epic journey to warmer climates, where they spend the winter months before returning to their nesting grounds in March/April. During migration, their flight is characterized by a slower, more buoyant rhythm compared to gulls, with distinctive wing beats that reflect their unique flying style.
Throughout their migratory journey and breeding season, common terns play a vital ecological role as both predators and prey in marine ecosystems. Their diet primarily consists of small fish, crustaceans, and other aquatic prey, which they capture using their sharp beaks and agile hunting techniques. By regulating prey populations and contributing to nutrient cycling in coastal habitats, common terns help maintain the delicate balance of marine ecosystems.
