Whiskered Tern
The whiskered tern (''Chlidonias hybrida'') is a tern in the family Laridae. The genus name is from Ancient Greek ''khelidonios'', "swallow-like", from ''khelidon'', "swallow". The specific ''hybridus'' is Latin for ''hybrid''; Peter Simon Pallas thought it might be a hybrid of white-winged black tern and common tern, writing "''Sterna fissipes 'Chlidonias leucopterus''et Hirundine 'Sterna hirundo''natam''”. This bird has a number of geographical races, differing mainly in size and minor plumage details. ''C. h. hybrida'' breeds in warmer parts of Europe and the Palearctic (northwestern Africa and central and southern Europe to southeastern Siberia, eastern China and south to Pakistan and northern India). The smaller-billed and darker ''C. h. delalandii'' is found in east and south Africa, and the paler ''C. h. javanicus'' from Java to Australia. The tropical forms are resident, but European and Asian birds winter south to Africa and the Indian Subcontinent. A tagged whi ...

Arctic Tern
The Arctic tern (''Sterna paradisaea'') is a tern in the family Laridae. This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe (as far south as Brittany), Asia, and North America (as far south as Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Recent studies have shown average annual round-trip lengths of about for birds nesting in Iceland and Greenland and about for birds nesting in the Netherlands. These are by far the longest migrations known in the animal kingdom. The Arctic tern nests once every one to three years (depending on its mating cycle). Arctic terns are medium-sized birds. They have a length of and a wingspan of . They are mainly grey and white plumaged, with a red/orange beak and feet, white forehead, a black nape and ...

Black-headed Gull
The black-headed gull (''Chroicocephalus ridibundus'') is a small gull that breeds in much of the Palearctic including Europe and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. Small numbers also occur in northeastern North America, where it was formerly known as the common black-headed gull. As is the case with many gulls, it was previously placed in the genus ''Larus''.
