Wilson's Snipe
Wilson's snipe (''Gallinago delicata'') is a small, stocky shorebird. The genus name ''gallinago'' is New Latin for a woodcock or snipe from Latin ''gallina'', "hen" and the suffix ''-ago'', "resembling". The specific ''delicata'' is Latin for "dainty". This species was considered to be a subspecies of the common snipe (''G. gallinago'') until 2003 when it was given its own species status, though not all authorities recognized this immediately. Wilson's snipe differs from the latter species in having a narrower white trailing edge to the wings, and eight pairs of tail feathers instead of the typical seven of the common snipe. Its common name commemorates the American ornithologist Alexander Wilson. Description Adults are in length with a wingspan. Weight ranges from . They have short greenish-grey legs and a very long straight dark bill. The body is mottled brown on top and pale underneath. They have a dark stripe through the eye, with light stripes above and below it. The wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Ord
George Ord, Jr. (March 4, 1781 – January 24, 1866) was an American zoologist who specialized in North American ornithology and mammalogy. Based in part on specimens collected by Lewis and Clark in the North American interior, Ord's article "Zoology of North America''"'' (1815), which was published in the second American edition of William Guthrie's ''Geographical, Historical, and Commercial Grammar'' (Johnson and Warner), has been recognized as the "first systematic zoology of America by an American". Ord (1815) published the first scientific descriptions of Pronghorn antelope (''Antilocapra americana''), Grizzly bear (''Ursus arctos horribilis'')'','' Meadow vole (''Microtus pennsylvanicus''), Bushy-tailed woodrat (''Neotoma cinerea''), Eastern gray squirrel (''Sciurus carolinensis pennsylvanicus''), Columbian ground squirrel (''Urocitellus columbianus''), Black-tailed prairie-dog (''Cynomys ludovicianus''), Bonaparte's gull (''Chroicocephalus philadelphia''), Ring-billed Gull ...

West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although the enc ...

Birding World
''Birding World'' was a monthly birding magazine published in the United Kingdom. It was the magazine of the Bird Information Service, based at Cley next the Sea, Norfolk. With the publication of issue No. 26/12 in January 2014, ''Birding World'' magazine ceased publication. History and profile Originally published in 1987 as ''Twitching'' volume 1, the magazine underwent a name-change to this name, in 1988 (also resetting its volume count back to 1). The editor was Steve Gantlett, and the assistant editor Richard Millington. It was aimed at birders with an interest in the occurrence and identification of rare birds in the United Kingdom and the Western Palearctic. It also covered birding-related material from around the globe. The range of material published included: * papers on bird identification, often including proposed new identification characters for difficult groups of taxa * news articles on rare birds in Britain and elsewhere in the Western Palearctic Significant a ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Boreal Owl
The boreal owl or Tengmalm's owl (''Aegolius funereus'') is a small owl in the "true owl" family Strigidae. It is known as the boreal owl in North America and as Tengmalm's owl in Europe after Swedish naturalist Peter Gustaf Tengmalm or, more rarely, Richardson's owl after Sir John Richardson. Due to the boreal owl's shyness and evasive reaction to human activities, nocturnal habits and preferred inaccessible taiga forest habitat, it is rarely seen by humans. Taxonomy The boreal owl was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. Linnaeus placed it with all the other owls in the genus ''Strix'' and coined the binomial name ''Strix funerea''. The Eurasian scops owl is now placed in the genus ''Aegolius'' that was introduced in 1829 by the German naturalist Johann Jakob Kaup with the boreal owl as the type species. The genus name is Latin for a screech owl, the word came from the Ancient Greek ''aigōlios' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drumming (snipe)
Drumming (also called bleating or winnowing) is a sound produced by snipe as part of their courtship display flights.Van Casteren, A, et al. “Sonation in the Male Common Snipe (Capella Gallinago Gallinago L.) Is Achieved by a Flag-like Fluttering of Their Tail Feathers and Consequent Vortex Shedding.” ''The Journal of Experimental Biology'', vol. 213, no. 9, 2010, pp. 1602–1608. The sound is produced mechanically (rather than vocally) by the vibration of the outer tail feathers when flying in a downwards, swooping motion. The drumming display is usually crepuscular, though it can also be heard at any point throughout the breeding season, as well as sporadically during their migration period. Drumming is commonly heard within the context of a mating display, but it can also be displayed as means of distraction when conspecific intruders or potential predators are in the area — this can benefit male snipe in attracting a female mate. The weather can also have an impact on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The state's capital and largest city is Columbus, with the Columbus metro area, Greater Cincinnati, and Greater Cleveland being the largest metropolitan areas. Ohio is bordered by Lake Erie to the north, Pennsylvania to the east, West Virginia to the southeast, Kentucky to the southwest, Indiana to the west, and Michigan to the northwest. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes". Its state flag is the only non-rectangular flag of all the U.S. states. Ohio takes its name from the Ohio River, which in turn originated from the Seneca word ''ohiːyo'', meaning "good river", "great river", or "large creek". The state arose from the lands west of the Appalachian Mountai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...
