Dalmatian Pelican
The Dalmatian pelican (''Pelecanus crispus''), also known as the curly-headed pelican, is the largest member of the pelican family and among the heaviest flying birds in the world. With a wingspan typically ranging between 2.7 and 3.2 meters (8.9–10.5 feet), it ranks among the largest soaring birds. These pelicans are known for their graceful flight and often travel in synchronized flocks. With a range spanning across much of Central Eurasia, from the eastern Mediterranean in the west to the Taiwan Strait in the east, and from the Persian Gulf in the south to Siberia in the north, it is a short-to-medium-distance Bird migration, migrant between breeding and overwintering areas. As with other pelicans, its diet is mainly fish, and the males are sexual dimorphism, larger than the females. Its curly nape feathers, grey legs and silvery-white plumage are distinguishing features, and the wings appear solid grey in flight. The adults acquire a Moulting, drabber plumage in winter, howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird Strike
A bird strike (sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)) is a collision between an airborne animal (usually a bird or bat) and a moving vehicle (usually an aircraft). The term is also used for bird deaths resulting from collisions with structures, such as power lines, towers and wind turbines (see bird–skyscraper collisions and towerkill). A significant threat to flight safety, bird strikes have caused a number of accidents with human casualties. There are over 13,000 bird strikes annually in the US alone. However, the number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about one accident resulting in human death in one billion (109) flying hours. The majority of bird strikes (65%) cause little damage to the aircraft; however, the collision is usually fatal to the bird(s) involved. Vultures and geese have been ranked the second and third most hazard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Von Kittlitz
Friedrich Heinrich, Freiherr von Kittlitz (16 February 1799 – 10 April 1874) was a Prussian artist, naval officer, explorer and naturalist. He was a descendant of a family of old Prussian nobility ("Freiherr" meaning "independent lord" - ranking with a baron). He collected specimens and made illustrations on major expeditions and wrote a few books on his travels. Several species were described on the basis of specimens collected by him and a few are named after him including Kittlitz's plover. Life and work Kittlitz was born in Breslau to Prussian Captain Friedrich (1769-1825) and Henriette Ehrenfried von Diebitsch (1771-1835). He went to grammar school in Oels and joined his father's battalion as a volunteer in 1813. He became a second lieutenant in the 16th Silesian Infantry Regiment and saw action at Glogau. He went to Paris in 1815 and was garrisoned in Mainz when the Landwehr regiments were dissolved. It was here that he became interested in nature after meeting Eduard Rü ...

Webbed Foot
The webbed foot is a specialized limb (anatomy), limb with interdigital webbing, interdigital membranes (webbings) that aids in aquatic locomotion, present in a variety of tetrapod vertebrates. This adaptation is primarily found in semiaquatic species, and has Convergent evolution, convergently evolved many times across vertebrate taxa. It likely arose from mutations in developmental genes that normally cause tissue between the digits to Apoptosis, apoptose. These mutations were beneficial to many semiaquatic animals because the increased surface area from the webbing allowed for more swimming propulsion and swimming efficiency, especially in surface swimmers. The webbed foot also has enabled other novel behaviors like escape responses and mating behaviors. A webbed foot may also be called a paddle to contrast it from a more hydrofoil-like Flipper (anatomy), flipper. Morphology A webbed foot has connecting tissue between the toes of the foot. Several distinct conditions can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crested Guineafowl
The crested guinea fowl (''Guttera'' sp.) are a group of three species and members of the Numididae, the guinea fowl bird family. They are found in open forest, woodland and forest-savanna mosaics in sub-Saharan Africa. Description They have a total length around 50 cm (20 in) and weigh .''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), . The plumage is overall blackish with dense white spots. They have distinctive black crests on the top of their heads, the form of which varies from small curly feathers to down depending upon subspecies, and which easily separates them from all other species of guinea fowl, except the plumed guinea fowl. The names "crested" and "plumed" are often misapplied across the species. Breeding They are monogamous with probable strong and long-lasting pair bonds. Courtship feeding is common, the author having seen a captive male run 5–10 m to the hen to present some particular morsel. The nest is a w ...

Chondrus Crispus
''Chondrus crispus''—commonly called Irish moss or carrageenan moss (Irish ''carraigín'', "little rock")—is a species of red algae which grows abundantly along the rocky parts of the Atlantic coasts of Europe and North America. In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its dry weight. The organism also consists of nearly 10% dry weight protein and about 15% dry weight mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour. Because of the abundant cell wall polysaccharides, it will form a jelly when boiled, containing from 20 to 100 times its weight of water. Description ''Chondrus crispus'' is a relatively small sea alga, reaching up to a little more than in length. It grows from a discoid holdfast and branches four ...

Romanticism In Science
19th-century science was greatly influenced by Romanticism (or the Age of Reflection, 1800–1840), an intellectual movement that originated in Western Europe as a counter-movement to the late-18th-century Enlightenment. Romanticism incorporated many fields of study, including politics, the arts, and the humanities. In contrast to the Enlightenment's mechanistic natural philosophy, European scientists of the Romantic period held that observing nature implied understanding the self and that knowledge of nature "should not be obtained by force". They felt that the Enlightenment had encouraged the abuse of the sciences, and they sought to advance a new way to increase scientific knowledge, one that they felt would be more beneficial not only to mankind but to nature as well. Romanticism advanced a number of themes: it promoted anti-reductionism (that the whole is more valuable than the parts alone) and epistemological optimism (man was connected to nature), and encouraged creativ ...
