Gaviiformes
Gaviiformes () is an order of aquatic birds containing the loons or divers and their closest extinct relatives. Modern gaviiformes are found in many parts of North America and northern Eurasia (Europe, Asia and debatably Africa), though prehistoric species were more widespread. Classification and evolution There are five living species, and all are placed in the genus '' Gavia''. The loons were formerly often considered to be the most ancient of the northern hemisphere bird families; this idea grew basically out of the perceived similarity of shape and (probably) habits between loons and the entirely unrelated extinct Cretaceous order Hesperornithiformes. In particular '' Enaliornis'', which was apparently an ancestral and plesiomorphic member of that order, was sometimes used to support claims of Albian (Early Cretaceous) Gaviiformes. More recently, it has become clear that the Anseriformes (waterfowl) and the Galliformes are the most ancient groups of modern birds, and these ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Loon
Loons (North American English) or divers (British English, British / Irish English) are a group of aquatic birds found in much of North America and northern Eurasia. All living species of loons are members of the genus ''Gavia'', family (biology), family Gaviidae and order (biology), order Gaviiformes. Description Loons, which are the size of large ducks or small goose, geese, resemble these birds in shape when swimming. Like ducks and geese, but unlike coots (which are Rallidae) and grebes (Podicipedidae), the loon's toes are connected by Bird feet and legs#Webbing and lobation, webbing. The loons may be confused with the cormorants (Phalacrocoracidae), but can be distinguished from them by their distinct call. Cormorants are not-too-distant relatives of loons, and like them are heavy-set birds whose bellies, unlike those of ducks and geese, are submerged when swimming. Loons in flight resemble plump geese with seagulls' wings that are relatively small in proportion to their bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Novopskov
Novopskov ( Ukrainian and Russian: ) is a rural settlement in the Starobilsk Raion of Luhansk Oblast in Ukraine. It is located on the Aidar, a left tributary of the Donets, in the basin of the Don. Population: Prior to 2020, it was the administrative centre of the former Novopskov Raion. On 19 September 2024, the Verkhovna Rada voted to rename Novopskov to Aidar as a part of the derussification campaign. Economy Transportation Bilokurakyne is connected by road with Starobilsk where it has further access to Highway H26 ro Svatove and Bilovodsk, as well as to Highway H21 to Luhansk. However, the section between Shchastia and Luhansk is controlled by the Luhansk People's Republic, and free movement from Shchastia to Luhansk is impossible. The closest railway station is in Starobilsk, on a railway line which is currently disconnected from the rest of the railway network in Ukraine. To the south, it extends to Kondrashivska Nova, in Stanytsia Luhanska, and to the north it cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
