Ecology: Behaviour This species is migratory, undergoing post-breeding dispersive movements north and south to favoured feeding grounds before migrating southward1. It breeds in dense colonies with other terns or Black-headed Gulls Larus ridibundus1 and is gregarious throughout the year, often forming feeding flocks where prey is abundant or concentrated (although it may also feed solitarily)2. Habitat Breeding During the breeding season the species forms colonies on sandy islands, rocky calcareous islets , sand-spits, sand-dunes, shingle beaches and extensive deltas2 with immediate access to clear waters with shallow sandy substrates rich in surface-level fish2. It shows a preference for raised, open, unvegetated sand , gravel , mud or bare coral substrates for nesting1. Non-breeding Outside of the breeding season the species frequents sandy or rocky beaches, mudflats fringed by mangroves , estuaries, harbours and bays , often feeding over inlets and at sea1. Diet Its diet consists predominantly of surface-dwelling marine fish2 9-15 cm long1 as well as small shrimps, marine worms and shorebird nestlings1. Breeding site The nest is a shallow scrape on raised, open, unvegetated sand, gravel, mud or bare coral substrates preferably far from upright vegetation1 on sandy islands, rocky calcareous islets, sand-spits, sand-dunes and shingle beaches2. The species forms very dense colonies during the breeding season in which the eggs of neighbouring pairs may only be 20 cm apart1. Management information The species responds favourably to habitat management such as vegetation clearance, and can be readily attracted to suitable nesting habitats by the use of decoys1. Breeding pairs are also known to be attracted to coastal locations where artificial nesting sites have been constructed (e.g. beaches of bare shingle and islands or rafts covered with sparse vegetation)4. A conservation scheme for the protection of gull and tern breeding colonies in coastal lagoons and deltas (e.g. Po Delta, Italy) involves protection from human disturbance , prevention of erosion of islet complexes, habitat maintenance and the creation of new islets for nest sites5. The scheme particularly specifies that bare islets with 30-100 % cover of low vegetation (sward heights less than 20 cm) should be maintained or created as nesting sites5. [2].
