Piney Orchard Nature Preserve
Piney Orchard Nature Preserve is a protected wetland forest with several miles of improved trails located in southern Odenton, Maryland. The Preserve is surrounded by 1,500 acres of river woodland between the residential communities of Piney Orchard, Two Rivers, Woodwardville, and Amberfield. Piney Orchard Nature Preserve is bordered by the Patuxent Research Refuge to the west, the Little Patuxent River to the south, and the Washington, Baltimore and Annapolis Trail to the east. Initiated in 1987, Constellation Real Estate (an Exelon Corporation subsidiary) started restoration of wetlands along the Little Patuxent River that had been mined for sand and gravel during the 1940s and '50s and remained deserted and unrestored. The mitigation projects--a term used for this type of restoration--followed five phases to replace wetlands filled in by the development of the 4,000-unit Piney Orchard residential community, which included the formation and enhancement of five large ponds and ...

Bitterns
Bitterns are birds belonging to the subfamily Botaurinae of the heron family Ardeidae. Bitterns tend to be shorter-necked and more secretive than other members of the family. They were called ''hæferblæte'' in Old English; the word "bittern" came to English from Old French ''butor'', itself from Gallo-Roman ''butitaurus'', a compound of Latin ''būtiō'' (buzzard) and ''taurus'' (bull). Bitterns usually frequent reed beds and similar marshy areas and feed on amphibians, reptiles, insects, and fish. Bitterns, like herons, egrets, and pelicans, fly with their necks retracted, unlike the similar storks, ibises, and spoonbill Spoonbills are a genus, ''Platalea'', of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name ''Platalea'' derives from Ancient Greek and means "broad", refe ...s, which fly with necks outstretched. Species There are currently 14 species divided into three genera ...

Landforms Of Anne Arundel County, Maryland
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Wetlands Of Maryland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (Anoxic waters, anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Discovery Trail
The American Discovery Trail is a system of recreational trails and roads that collectively form a coast-to-coast hiking and biking trail across the mid-tier of the United States. Horses can also be ridden on most of this trail. The coastal trailheads are the Delmarva Peninsula on the Atlantic Ocean and the northern California coast on the Pacific Ocean. The trail has northern and southern alternates for part of its distance, passing through Chicago and St. Louis respectively. The total length of the trail, including both the north and south routes, is . The northern route covers with the southern route covering . It is the only non-motorized coast-to-coast trail. The trail passes through 14 national parks and 16 national forests and uses sections of or connects to five National Scenic Trails, 10 National Historic Trails, and 23 National Recreation Trails. For part of its distance, it is coincident with the North Country Trail, the Buckeye Trail, the Continental Divide Trail, ...

Northeast Corridor
The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, Stamford, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily. The corridor is used by many Amtrak trains, including the high-speed Acela, intercity trains and several long-distance trains. Most of the corridor also has frequent commuter rail service, operated by the MBTA, Shore Line East, Hartford Line, Metro-North Railroad, Long Island Rail Road, New Jersey Transit, SEPTA and MARC. While large through freights have not run on the NEC since the early 1980s, several companies continue to run smaller local freights over some select few sections ...

Anas
''Anas'' is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name ''Anas'' is the Latin for "duck". Systematics The genus ''Anas'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae''. ''Anas'' is the Latin word for a duck. The genus formerly included additional species. In 2009 a large molecular phylogentic study was published that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae. The results confirmed some of the conclusions of earlier smaller studies and indicated that the genus as then defined was non-monophyletic. Based on the results of this study, ''Anas'' was split into four proposed monophyletic genera with five ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merlin (bird)
The merlin (''Falco columbarius'') is a small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia. A bird of prey once known colloquially as a pigeon hawk in North America, the merlin breeds in the northern Holarctic; some migrate to subtropical and northern tropical regions in winter. Males typically have wingspans of , with females being slightly larger. They are swift fliers and skilled hunters who specialize in preying on small birds in the size range of sparrows to quail. The merlin has for centuries been well regarded as a falconry bird. In recent decades merlin populations in North America have been significantly increasing, with some merlins becoming so well adapted to city life that they forgo migration. Nomenclature The merlin was described and illustrated by the English naturalist Mark Catesby (as the "pigeon hawk") in his ''Natural history of Carolina, Florida and the Bahama Islands'' published in 1729–17 ...

Mergansers
''Mergus'' is the genus of the typical mergansers , fish-eating ducks in the subfamily Anatinae. The genus name is a Latin word used by Pliny the Elder and other Roman authors to refer to an unspecified waterbird. The common merganser (''Mergus merganser'') and red-breasted merganser (''M. serrator'') have broad ranges in the northern hemisphere. The Brazilian merganser (''M. octosetaceus'') is a South American duck, and one of the six most threatened waterfowl in the world, with possibly fewer than 250 birds in the wild. The scaly-sided merganser or "Chinese merganser" (''M. squamatus'') is an endangered species. It lives in temperate East Asia, breeding in the north and wintering in the south. The hooded merganser (''Lophodytes cucullatus'', formerly known as ''Mergus cucullatus'') is not of this genus but is closely related. The other "aberrant" merganser, the smew (''Mergellus albellus''), is phylogenetically closer to goldeneyes (''Bucephala''). Although they are sead ...

Juncos
Juncos (, ) is a town and one of the 78 municipalities of Puerto Rico. It is located in the eastern central region of the island to the west of the Caguas Valley, south of Canóvanas and Carolina; southeast of Gurabo; east of San Lorenzo; and west of Las Piedras. Juncos is spread over 9 barrios and Juncos barrio-pueblo (the downtown area and administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. Juncos was founded on the request of Tomás Pizarro on August 2, 1797, having previously been a village which evolved from a small ranch, the ''Hatillo de los Juncos''. This ranch was part of the ''Hato del Valenciano'', which gave its name to the Río Valenciano which bisects the city before joining the Río Gurabo to the north of the settlement. ''Juncos'' is Spanish for reeds. History During the 17th century, large parts of the municipality were owned by the ''Hato Grande de los Delgado'' (The Delgados' Great Ranch). Anot ...

Herons
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and '' Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Hawks
Hawks are birds of prey of the family Accipitridae. They are widely distributed and are found on all continents except Antarctica. * The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks and others. This subfamily are mainly woodland birds with long tails and high visual acuity. They hunt by dashing suddenly from a concealed perch. * In America, members of the ''Buteo'' group are also called hawks; this group is called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged, shorter-tailed and fly further distances in open areas than accipiters. Buteos descend or pounce on their prey rather than hunting in a fast horizontal pursuit. The terms ''accipitrine hawk'' and ''buteonine hawk'' are used to distinguish between the types in regions where ''hawk'' applies to both. The term ''"true hawk"'' is sometimes used for the accipitrine hawks in regions where ''buzzard'' is preferred fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
