Senegal Thick-knee
The Senegal thick-knee (''Burhinus senegalensis'') is a stone-curlew, a group of waders in the family Burhinidae. Their vernacular scientific name refers to the prominent joints in the long yellow or greenish legs. Range It is a resident breeder in Africa between the Sahara and the equator, and in the Nile valley. Description left, Senegal thick-knees are medium-large waders with strong black and yellow black bills, large yellow eyes — which give them a reptilian appearance — and cryptic plumage. They are similar but slightly smaller than the Eurasian stone-curlew, which winters in Africa. The long dark bill, single black bar on the folded wing, and darker cheek stripe are distinctions from the European species. Senegal thick-knee is striking in flight, with a broad white wing bar. Habits and food left, 200px, This species has a preference for dry open habitats with some bare ground, preferably near water. It lays two blotchy light brown eggs on a ground scrape ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia.

Birds Of Sub-Saharan Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, ...

Burhinus
''Burhinus'' is a genus of birds in the family Burhinidae. This family also contains the genus ''Esacus''.del Hoyo J, Elliott A, Sargatal J (1996) ''Handbook of the Birds of the World'', ''vol 3.'' Lynx, Barcelona The genus name ''Burhinus'' comes from the Greek language, Greek ''bous'', ox, and ''rhis'', nose. The ''Burhinus'' are commonly called thick-knee, stone-curlew or dikkop. They are medium-sized, terrestrial waders, though they are generally found in semi-arid to arid, open areas. Only some species of ''Burhinus'' are associated with water. The genus ranges from 32 cm to 59 cm in size. ''Burhinus'' are characterised by their long legs, long wings and cryptic plumage. Most species have a short, thick, strong bill,Marchant, S., & P.J.

British Birds (journal)
''British Birds'' is a monthly ornithology magazine that was established in 1907. It is now published by BB 2000 Ltd, which is wholly owned by The British Birds Charitable Trust (registered charity number 1089422), established for the benefit of United Kingdom, British ornithology. Its circulation in 2000 was 5,250 copies; its circulation peaked at 11,000 in the late 1980s. The current editor is Stephen Menzie. ''British Birds'' is aimed at serious birdwatching, birdwatchers and ornithologists, rather than the more casual birdwatchers catered for by some other magazines on the subject. It publishes the findings of the British Birds Rarities Committee. Its mascot, and later logo, the red grouse, was chosen because at the time it was then considered an Endemism, endemic British species; though subsequently long considered a subspecies of the Willow ptarmigan, willow grouse, further study resulted in it being returned to separate species status in 2024. In 1916, ''British Birds'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shirihai, Hadoram
Hadoram Shirihai (; born in Israel 1962) is an Israeli ornithologist and writer. Biography Shirihai is the son of Batia and Eli Shirihai. His mother was a schoolteacher, his father was a zoologist in Israel. He grew up in Jerusalem where he became fascinated with birds when he was 13 and spent much time documenting shorebird behaviour, raptor breeding biology and participating in bird migration surveys. In the 1980s and 1990s, he lived in Eilat on Israel's Red Sea coast, where he founded the International Birdwatching Center, becoming its first director. Scientific career Shirihai was behind the discovery of several new species in the Western Palearctic and Israel. He guided birding trips into the southern Negev desert, showing many observers locally breeding Hume's tawny owl and Nubian nightjar among other little-watched species of the area. He has written a number of bird identification papers, mostly published in English in magazines such as '' British Birds'' and ''Birding ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs.

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Eurasian Stone-curlew
The Eurasian stone-curlew, Eurasian thick-knee, or simply stone-curlew (''Burhinus oedicnemus'') is a northern species of the Burhinidae ( stone-curlew) bird family. Taxonomy The Eurasian stone-curlew was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Charadrius oedicnemus''. He specified the locality as England. The name ''Oedicnemus'' had been used earlier by the French naturalist Pierre Belon in 1655. The species is now placed in the genus ''Burhinus'' that was introduced by the German zoologist Johann Karl Wilhelm Illiger in 1811. The genus name combines the Greek ' meaning "ox" with ' meaning "nose". The species name ''oedicnemus'' combines the Greek meaning "to swell", and meaning "shin" or "leg", referring to the bird's prominent tibiotarsal joints, which also give it the common name of "thick-knee". This is an abbreviated form of Thomas Pennant's 1776 coinage "thick-kneed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
