Ordnance Datum
In the British Isles, an ordnance datum or OD is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps. A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. In particular: * In Great Britain, OD for the Ordnance Survey is ODN (Ordnance Datum Newlyn), defined as the MSL as recorded by the tidal gauge at Newlyn in Cornwall between 1915 and 1921. **Prior to 1921, OD was defined as MSL as recorded in the Victoria Dock, Liverpool, during a short period in 1844 (ODL). * In Northern Ireland, OD for the Ordnance Survey of Northern Ireland is Belfast Ordnance Datum, the MSL at Clarendon Dock, Belfast, between 1951 and 1956. * In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the MSL at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969.

Royal Society For The Protection Of Birds
The Royal Society for the Protection of Birds (RSPB) is a charitable organisation registered in England and Wales and in Scotland. It was founded in 1889. It works to promote conservation and protection of birds and the wider environment through public awareness campaigns, petitions and through the operation of nature reserves throughout the United Kingdom. In 2020/21 the RSPB had an income of £117 million, 2,000 employees, 12,000 volunteers and 1.1 million members (including 195,000 youth members), making it one of the world's largest wildlife conservation organisations.

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''. The genus name '' Chroicocephalus'' is from Ancient Greek ''khroizo'', "to colour", and ''kephale'', "head". The specific ''ridibundus'' is Latin for "laughing", from ''ridere'' "to laugh". The black-headed gull displays a variety of compelling behaviours and adaptations. Some of these include removing eggshells from one's nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are an overwintering species, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Tern
The little tern (''Sternula albifrons'') is a seabird of the family Laridae. It was formerly placed into the genus ''Sterna'', which now is restricted to the large white terns. The genus name is a diminutive of ''Sterna'', "tern". The specific ''albifrons'' is from Latin ''albus'', "white", and "frons", ''forehead''. The former North American (''S. a. antillarum'') and Red Sea ''S. a. saundersi'' subspecies are now considered to be separate species, the least tern (''Sternula antillarum'') and Saunders's tern (''Sternula saundersi''). This bird breeds on the coasts and inland waterways of temperate and tropical Europe and Asia. It is strongly migratory, wintering in the subtropical and tropical oceans as far south as South Africa and Australia. There are three subspecies, the nominate ''albifrons'' occurring in Europe to North Africa and western Asia; ''guineae'' of western and central Africa; and ''sinensis'' of East Asia (SE Russia to Japan, SE Asia, Philippines) and the nort ...
