Pacific Flyway
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. Any given bird species travels roughly the same route every year, at almost the same time. Ornithologists and Birdwatching, birdwatchers can often predict to the day when a particular species will show up in their area. Notable locations Along the Pacific Flyway, there are many key rest stops where birds of many species gather, sometimes in the millions, to feed and regain their strength before continuing. Some species may remain in these rest stops for the entire season, but most stay a few days before moving on. * Boundary Bay, British Columbia, has been listed as an Important Bird Area by the Canadian government in recognition of its value to migratory birds. * Grays Ha ...

Coyote Valley, California
Coyote Valley is an area located in a narrowing of the southern Santa Clara Valley, in Northern California. Coyote Valley is approximately in size and largely composed of farmland, orchards, open space preserves, and homes. Coyote Valley is generally divided into three sections: North Coyote Valley (which is part of San Jose), the unincorporated village of Coyote, California (which is located in North Coyote Valley), and South Coyote Valley (which is part of Morgan Hill). Coyote Valley is one of the largest greenbelts in the San Francisco Bay Area. Much of Coyote Valley is preserved as open space, nature reserve, or protected farmland. The area was threatened by large-scale development in the early 2000s, which drew criticism from the public, resulting in the abandonment of the redevelopment plans and the establishment of the conservation policy which governs the valley. The Coyote Gap at the extreme north end of Coyote Valley is a critical wildlife corridor for safe passag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco Bay
San Francisco Bay (Chochenyo language, Chochenyo: 'ommu) is a large tidal estuary in the United States, U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the cities of San Francisco, California, San Francisco, San Jose, California, San Jose, and Oakland, California, Oakland. The San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento River, Sacramento and San Joaquin River, San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Convention, Ramsar Wetland of International Importance on February 2, 2013, and the Port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inverted River Delta
An inverted river delta is a river delta in which the narrow end of the delta emerges on the seafront and the wide end is located further inland, so that with respect to the seafront, the locations of both ends of the delta are inverted. Explanation River deltas typically form on flat, coastal floodplains: the narrow end located at the point where a river fans out and deposits sediment in a region extending outward into the body of water which the river empties. In the case of an inverted delta, the delta is located at the waterway's exit from a large, flat valley, yet still inside the valley. The sediment is dropped within the valley and the clear water then exits into a bay or the ocean, so the apex of the delta is at this exit, a configuration said to be inverted from that usually seen. Inverted deltas typically do not last long in geological terms, since they tend to fill up with sediments rather quickly and eventually become normal deltas. Examples The Sacramento-San Jo ...

Suisun Marsh
Located in northern California, the Suisun Marsh ( ) has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of a tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento River, Sacramento and San Joaquin River, San Joaquin rivers between Martinez, California, Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary. The Suisun Marsh is named for the Suisunes, a Patwin/Wintun sub-tribe, who inhabited the area around 200 years ago. Overview Suisun Marsh, 116,000 acres (470 km2) of land, bays, and sloughs, is one of the largest Estuary, estuarine marshes in the western United States. Geologically, the Suisun Marsh is the pro ...

Great Basin
The Great Basin () is the largest area of contiguous endorheic watersheds, those with no outlets to the ocean, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrographic, biological, floristic, physiographic, topographic, and ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature of the landform as "having no connection to the ocean". The hydrographic defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summer Lake Wildlife Area
The Summer Lake Wildlife Area (also known as Summer Lake State Game Management Area) is a wildlife refuge located on the northwestern edge of the Great Basin drainage in south-central Oregon. It is administered by the Oregon Department of Fish and Wildlife. The refuge is an important stop for waterfowl traveling along the Pacific Flyway during their spring and fall migrations. The Summer Lake Wildlife Area also provides habitat for shorebirds and other bird species as well as wide variety of mammals and several fish species.
