Oaks Bottom Wildlife Refuge
Oaks Bottom Wildlife Refuge is a city park of about in southeast Portland, in the U.S. state of Oregon. Located in a floodplain along the east bank of the Willamette River near Sellwood, the park is known for attracting a wide variety of birds. In 1988, the park was named Portland's first wildlife refuge, and in 2004, it was designated the city's first migratory bird park. Description The elongated park includes a shallow seasonal lake and wetland, open grassy areas, and mixed maple and oak woodlands, among other habitats. A hiking and biking path called the Springwater Corridor runs through the park parallel to the Willamette River. The corridor runs alongside the Oregon Pacific Railway tracks which can be seen on a berm next to the path. Slightly south of the refuge are Sellwood Park and Sellwood Riverfront Park. Oaks Amusement Park is to the west, near the river. To the east, the top of a bluff above the lake is mainly residential, though one of the buildings is a mausoleum and ...

Urban Park
An urban park or metropolitan park, also known as a municipal park (North America) or a public park, public open space, or municipal gardens ( UK), is a park in cities and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation, and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company. Common features of municipal parks include playgrounds, gardens, hiking, running and fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, and/or picnic facilities, depending on the budget and natural features available. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provide multiple benefits.

Rookery
A rookery is a colony of breeding animals, generally gregarious birds. Coming from the nesting habits of rooks, the term is used for corvids and the breeding grounds of colony-forming seabirds, marine mammals (true seals and sea lions), and even some turtles. Rooks (northern-European and central-Asian members of the crow family) have multiple nests in prominent colonies at the tops of trees. Paleontological evidence points to the existence of rookery-like colonies in the pterosaur ''Pterodaustro''. The term ''rookery'' was also borrowed as a name for dense slum housing in nineteenth-century cities, especially in London. See also *Auca Mahuevo, for a titanosaurid sauropod dinosaur rookery *Bird colony *Heronry *Rook shooting Rook shooting was a previously popular sport in the United Kingdom, in which young rooks were shot from tree branches, often using purpose-built rifles known as rook rifles. Rook shooting could serve as a form of pest control, a blood sport ... R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gull
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Osprey
The osprey (''Pandion haliaetus''), , also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described by Carl Linnaeus under the name ''Falco haliaeetus'' in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawk
Hawks are bird of prey, 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'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egret
Egrets ( ) are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes (usually milky white) during the breeding season. Egrets are not a biologically distinct group from herons and have the same build. Biology Many egrets are members of the genera ''Egretta'' or '' Ardea'', which also contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word "egret" comes from the French word ''aigrette'' that means both "silver heron" and "brush", referring to the long, filamentous feathers that seem to cascade down an egret's back during the breeding season (also called "egrets"). Several of the egrets have been reclassified from one genus to another in recent years; the great egret, for example, has been classified as a member of either ''Casmerodius'', ''Egretta'', or ''Ardea''. In the 19th and early part of the 20th centuries, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahonia Aquifolium
''Mahonia aquifolium'', the Oregon grape or holly-leaved barberry, is a species of flowering plant in the family Berberidaceae, native to western North America. It is an evergreen shrub growing tall and wide, with pinnate leaves consisting of spiny leaflets, and dense clusters of yellow flowers in early spring, followed by dark bluish-black berries. The berries are included in the diet of some aboriginal peoples of the Pacific Northwest, and the species is recognized as the state flower of Oregon. Description ''M. aquifolium'' grows to tall by wide. The stems and twigs have a thickened, corky appearance. The leaves are pinnate and up to long, comprising spiny leaflets.

Gondola Lift
A gondola lift is a means of cable transport and type of aerial lift which is supported and propelled by cables from above. It consists of a loop of steel wire rope that is strung between two stations, sometimes over intermediate supporting towers. The cable is driven by a bullwheel in a terminal, which is typically connected to an engine or electric motor. It is often considered a ''continuous system'' since it features a haul rope which continuously moves and circulates around two terminal stations. In contrast, an aerial tramway operates solely with fixed grips and simply shuttles back and forth between two end terminals. The capacity, cost, and functionality of a gondola lift will differ dramatically depending on the combination of cables used for support and haulage and the type of grip (detachable or fixed). Because of the proliferation of such systems in the Alps, the it, Cabinovia and french: Télécabine are also used in English-language texts. The systems m ...
