Savage Mill Trail
The Savage Mill Trail is a rail trail that winds along the Little Patuxent River in Savage, Maryland. The trail was formerly part of the Baltimore and Ohio Railroad's rail corridor through central Maryland, but the Howard County, Maryland, Howard County Recreation and Parks Department acquired the land in 1978. Historical development Historical significance The Savage Mill Trail is located in an area that became a major manufacturing center in the early 1800s. Near the beginning of the trail is a textile mill that was built between 1816 and 1823. This mill along with other manufacturing companies in the area utilized the currents of the Little and Middle Patuxent Rivers to power their factories. At the beginning of the trail is a Bollman truss bridge, which was used by the Baltimore and Ohio Railroad during the middle of the 19th century. The Bollman truss bridge was invented in 1850 and was the first system to be made entirely of iron. This bridge was built in 1869 and ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Flycatcher
The least flycatcher (''Empidonax minimus'') (also called chebec, or chebecker, after the sound it makes) is a small insect-eating bird. It is the smallest ''Empidonax'' flycatcher in eastern North America. Taxonomy The closest relative to the least flycatcher was long thought to be the Hammond's flycatcher based on similarities in their songs and appearances. However, mitochondrial DNA analysis has revealed that the least flycatcher diverges significantly from its congeners and does not possess any sister taxa. Description The least flycatcher is hard to distinguish from the other birds of its genus. The bird is one of the smallest of the genus ''Empidonax'', measuring 12 to 14 cm in height with a wingspan of 19 to 22 cm and weighing approximately 10.3 g. Its plumage is dull olive-gray on its back and whitish on its belly, notably brighter than the other ''Empidonax'' birds. The least flycatcher's wings are lined with two white bars, and white rings contour its ey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carp
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bl ...

Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Lining The Patuxent River
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluegill
The bluegill (''Lepomis macrochirus''), sometimes referred to as "bream", "brim", "sunny", or "copper nose" as is common in Texas, is a species of North American freshwater fish, native to and commonly found in streams, rivers, lakes, ponds and wetlands east of the Rocky Mountains. It is the type species of the genus ''Lepomis'' (true sunfish), from the family Centrarchidae (sunfishes, crappies and black basses) in the order Perciformes (perch-like fish). Bluegills can grow up to long and about . While their color can vary from population to population, they typically have a very distinctive coloring, with deep blue and purple on the face and gill cover, dark olive-colored bands down the side, and a fiery orange to yellow belly. They are omnivorous and will consume anything they can fit in their mouth, but mostly feed on small aquatic insects and baitfishes. The fish are important prey for bass, other larger sunfish, northern pike and muskellunge, walleye, trout, herons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White-tailed Deer
The white-tailed deer (''Odocoileus virginianus''), also known as the whitetail or Virginia deer, is a medium-sized deer native to North America, Central America, and South America as far south as Peru and Bolivia. It has also been introduced to New Zealand, all the Greater Antilles in the Caribbean (Cuba, Jamaica Jamaica (; ) is an island country situated in the Caribbean Sea. Spanning in area, it is the third-largest island of the Greater Antilles and the Caribbean (after Cuba and Hispaniola). Jamaica lies about south of Cuba, and west of His ..., Hispaniola, and Puerto Rico), and some countries in Europe, such as the Czech Republic, Finland, France, Germany, Romania and Serbia. In the Americas, it is the most widely distributed wild ungulate. In North America, the species is widely distributed east of the Rocky Mountains as well as in southwestern Arizona and most of Mexico, except Baja California peninsula, Lower California. It is mostly displaced by the black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raccoon
The raccoon ( or , ''Procyon lotor''), sometimes called the common raccoon to distinguish it from other species, is a mammal native to North America. It is the largest of the procyonid family, having a body length of , and a body weight of . Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. Three of the raccoon's most distinctive features are its extremely dexterous front paws, its facial mask, and its ringed tail, which are themes in the mythologies of the indigenous peoples of the Americas relating to the animal. The raccoon is noted for its intelligence, as studies show that it is able to remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates. The original habitats of the raccoon are deciduous and mixed forests, but due to their adaptability, they have extended their range to mountainous areas, coastal marshes, and urban ...

Eastern Gray Squirrel
The eastern gray squirrel (''Sciurus carolinensis''), also known, particularly outside of North America, as simply the grey squirrel, is a tree squirrel in the genus ''Sciurus''. It is native to eastern North America, where it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the eastern gray squirrel in Europe, in particular, is regarded as an invasive species. In Europe, ''Sciurus carolinensis'' is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. Distribution ''Sciurus carolinensis'' is native to the eastern and midwestern United States, and to the southerly portions of the central provinces of Canada. The native range of the eastern gray squirrel overlaps with that of the fox squirre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Chipmunk
The eastern chipmunk (''Tamias striatus'') is a chipmunk species found in eastern North America. It is the only living member of the chipmunk genus ''Tamias''. Etymology The name "chipmunk" comes from the Ojibwe word ''ajidamoo'' (or possibly ''ajidamoonh'', the same word in the Ottawa dialect of Ojibwe), which translates literally as "one who descends trees headlong." First described by Mark Catesby in his 1743 ''The Natural History of Carolina, Florida, and the Bahama Islands'', the chipmunk was eventually classified as ''Sciurus striatus'' by Linnaeus, meaning "striped squirrel" in Latin. The scientific name was changed to ''Tamias striatus'', meaning "striped steward," by Johann Illiger in 1811. Description A small species, it reaches about in length including the tail, and a weight of . It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. It has lighter fur on the lower part ...

Yellow-throated Warbler
The yellow-throated warbler (''Setophaga dominica'') is a small migratory songbird species breeding in temperate North America. It belongs to the New World warbler family (Parulidae). Description In summer, male yellow-throated warblers display grey upperparts and wings, with double white wing bars. Their throats are yellow, and the remainder of their underparts are white, and are streaked with black on the flanks. Their heads are strongly patterned in black and white, with a long supercilium; the different subspecies may display yellow and white superciliums. Remiges and rectrices are black. They measure long. Other plumages of these birds – females immatures and non-breeding males – resemble washed-out versions of the summer males; in particular they have a less crisply defined strong head pattern. They also have less bright yellows, and dark grey feathers instead of black ones in the body plumage. Compared to many other New World warblers, sexual dimorphism is slight h ...

Prothonotary Warbler
The prothonotary warbler (''Protonotaria citrea'') is a small songbird of the New World warbler family. It is named for its plumage which resembles the yellow robes once worn by papal clerks (named prothonotaries) in the Roman Catholic church. The prothonotary warbler is the only member of the genus ''Protonotaria'' and the only eastern warbler that nests in natural or artificial cavities. Taxonomy The prothonotary warbler was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his '' Histoire Naturelle des Oiseaux'' from a specimen collected in Louisiana. Buffon coined the French name ''Le figuier protonotaire''. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle,'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
