larus marinus การใช้

There are large numbers of nesting herring gulls ( Larus argentatus ) and great black-backed gulls ( Larus marinus ) on the island and a small rookery of black-crowned night-herons ( Nycticorax nycticorax ) and a few snowy egrets ( Egretta thula ).
Some gull species are highly adaptable . " Nocturnal Scavenging by Gulls in the Southern North Sea " is one study that mentions nocturnal activity ( following trawlers and their discard ) among " Larus argentatus ", " Larus marinus ", and " Larus fuscus ".
Aerial predators of the Atlantic puffin include the great black-backed gull ( " Larus marinus " ), the great skua ( " Stercorarius skua " ), and similar-sized species, which can catch a bird in flight, or attack one that is unable to escape fast enough on the ground.
Several species nest on the island including the largest breeding colony of Cormorant ( " Phalacrocorax carbo " ) in the Isles of Scilly as well as Puffin, Great Black backed Gull ( " Larus marinus " ), Razorbill ( " Alca torda " ) and Common Shag ( " Phalacrocorax aristotelis " ).
The island has a significant breeding colony of over 4, 000 pairs of lesser black-backed gulls ( " Larus fuscus " ), 400 pairs of herring gulls ( " Larus argentatus " ), 2 pairs of great black-backed gulls ( " Larus marinus " ) and varying numbers of common shelduck ( " Tadorna tadorna " ) and Eurasian oystercatchers ( " Haematopodidae " ).
