Heligoland Trap
A Heligoland trap (or funnel trap) is a large, building-sized, funnel-shaped, rigid structure of wire mesh or netting used to trap birds, so that they can be banded or otherwise studied by ornithologists. The name is taken from the site of the first such trap, the Heligoland Bird Observatory on the island of Heligoland Heligoland (; , ; Heligolandic Frisian: , , Mooring Frisian: , ) is a small archipelago in the North Sea. The islands were historically possessions of Denmark, then became possessions of the United Kingdom from 1807 to 1890. Since 1890, the ..., Germany, where it was developed by Hugo Weigold who established the observatory and initiated the banding program there. The trap has a series of linked funnels that guides birds or other animals in but makes it hard for them to leave. Funnel traps of smaller size can also be used to trap squirrels and insects. Rybachy trap The Rybachy trap is a variation or expansion of the Heligoland trap in that it is a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Ringing
Bird ringing (UK) or bird banding (US) is the attachment of a small, individually numbered metal or plastic tag to the leg or wing of a wild bird to enable individual identification. This helps in keeping track of the movements of the bird and its life history. It is common to take bird measurement, measurements and examine the conditions of feather moult, subcutaneous fat, age indications and sex during capture for ringing. The subsequent recapture, recovery, or observation of the bird can provide information on bird migration, migration, longevity, mortality, population, territoriality, List of feeding behaviours, feeding behaviour, and other aspects that are studied by ornithology, ornithologists. Other methods of marking birds may also be used to allow for field based identification that does not require capture. History The earliest recorded attempts to mark birds were made by Roman army, Roman soldiers. For instance during the Punic Wars in 218 BC a crow was released b ...

Ornithology
Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guild (ecology), guilds, insular biogeography, phylogeography, and bird conservation, conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories.

Heligoland Bird Observatory
The Heligoland Bird Observatory (''Vogelwarte Helgoland'' in German), one of the world's first ornithological observatories, is operated by the Ornithologische Arbeitsgemeinschaft Helgoland e.V., a non-profit organization which was founded in 1891 to support research on the fauna of Heligoland, a small German archipelago, comprising the islands of Heligoland and Düne, in the Heligoland Bight of the North Sea. The principal research focus is on bird migration through banding studies. Over 400 species have been recorded. OAG Helgoland produces an annual bird report. History Heligoland is on a major migration route for birds crossing the North Sea; for centuries, both those on migration and those breeding there, were an important source of food for the islanders. In the early 19th century Heligoland also became a source of bird specimens for collectors and museums. Ornithologist and artist Heinrich Gätke first visited the island in 1837 and moved there permanently in 1841 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heligoland
Heligoland (; , ; Heligolandic Frisian: , , Mooring Frisian: , ) is a small archipelago in the North Sea. The islands were historically possessions of Denmark, then became possessions of the United Kingdom from 1807 to 1890. Since 1890, they have been part of the German state of Schleswig-Holstein, although they were managed by the United Kingdom as a war prize from 1945 to 1952. The islands are located in the Heligoland Bight (part of the German Bight) in the southeastern corner of the North Sea and had a population of 1,127 at the end of 2016. They are the only German islands not in the vicinity of the mainland. They lie approximately by sea from Cuxhaven at the mouth of the River Elbe. In addition to German, the local population, who are ethnic Frisians, speak the Heligolandic dialect of the North Frisian language called . During a visit to the islands in 1841, August Heinrich Hoffmann von Fallersleben wrote the lyrics to the "", which became the national anthem o ...

Hugo Weigold
Max Hugo Weigold (27 May 1886 – 9 July 1973) was a German zoologist and a pioneer bird bander who worked at the Heligoland Bird Observatory, one of the world's first bird-ringing sites. Weigold was born in Dresden. He studied natural sciences and geography in Jena and Leipzig. Here he was influenced by Ernst Haeckel, Richard Woltereck, Otto zur Strassen and Carl Chun. He worked for the Scientific Commission for Marine Research in Heligoland, a German island in the North Sea, where he continued the work of Heinrich Gätke (who died in 1897) in bird migration studies, setting up the bird observatory in 1910 to trap and band the migratory birds passing through the island. For six years Weigold carried out zoological research in China and Tibet and was the first Westerner to see a live giant panda in the wild, buying a cub (which did not survive for long) while part of the Stoetzner Expedition in 1916. He later became Director of Natural Sciences at the Lower Saxony State Mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rossitten Bird Observatory
The Rossitten Bird Observatory (''Vogelwarte Rossitten'' in German) was the world's first ornithological observatory. It was sited at Rossitten, East Prussia (now Rybachy, Kaliningrad Oblast, Russia), on the Curonian Spit on the south-eastern coast of the Baltic Sea. It was established by German ornithologist Johannes Thienemann and operated until 1944. In 1945 East Prussia was divided between Poland, Russia and Lithuania, and most ethnic Germans expelled. History The 98 km long Curonian Spit is a thin sand peninsula, ranging from about 400 m to 4 km in width, that separates the Baltic Sea from the shallow Curonian Lagoon. It has several settlements along its length. It lies on a major migration route for birds following the coastline of the eastern Baltic. The richness of birdlife was first noticed by Friedrich Lindner who was a close friend of Johannes Thienemann. Thienemann first visited the fishing village of Rossitten there in 1896 where he experienced “a bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ventė Cape
Ventė Cape (, ), sometimes referred to as Ventė Horn or Ventė Peninsula, is a peninsula in the Nemunas Delta, in Šilutė district, Lithuania. It is known as a resting place for birds during their Bird migration, migration, particularly in autumn. Ventė Cape Ornithological Station – one of the first bird ringing stations in Europe still in operation – was opened here by Tadas Ivanauskas in 1929. Cape Ventė was formed 4,500-5,000 years ago when the Curonian Lagoon flooded a ridge of coastal moraine formations during the last stage of the Baltic Sea Geology of the Baltic Sea, glaciation. In the 1980s and 1990s, the tip of Cape Vente was reinforced, the banks were raised and paved with stones. A 250 meters long Breakwater (structure), breakwater has been built, which also acts as an icebreaker at the end of winter, breaking up large blocks of ice. This process helped to halt the deterioration of the Cape Ventė Peninsula. Cape Ventė has a red brick lighthouse standing ...
