The Yuma clapper rail (Rallus longirostris yumanensis) is a federally endangered species and 90% of the U.S. population exists in only 2 wetlands. . A few of the subspecies of this bird, such as the Yuma clapper rail, are freshwater birds. It has a grayish-green back and wings, whitish throat, light grey-olive breast, and pale yellow belly. The clapper rail is mainly a saltwater bird, and its preferred habitat is coastal saltwater marshes and mangrove swamps. It supports nearly 75% of the total population of the Yuma Clapper Rail, an endemic marshbird of the Lower Colorado River and its delta that is protected as Endangered in the United States and Threatened in Mexico. wetland habitat currently available in the study area Annual marsh bird surveys along the Wash . Habitat California clapper rail are similar to marsh types used by the endangered Light-footed clapper rail (R. l. levipes) of Southern California (Zembal et al. Encyclopedia.com. Conway 1998, Conway and Eddleman 2000) as a possible method to restore Yuma clapper rail populations in the absence of major seasonal flooding events. Over the next 40 years, Yuma clapper rails were found more and more frequently on the Colorado River in Arizona and California. The Yuma clapper rail is the largest rail found along the lower Colorado River. Description An estuary is a zone where a river flows into the sea, mixing freshwater with saltwater.

Eventually, a mat of dead cattails forms in the shallows, providing nesting cover for rails. Habitat: Salt marshes along the coast, also brackish and freshwater marshes inland. Also known as the Yuma Clapper Rail Photo by Courtney Conway, USGS The Department of Interior abruptly changed its assessment regarding the threat posed to the endangered Yuma Ridgway's rail (also called the Yuma Clapper rail ) by industrial-scale solar projects, clea Along the Pacific Coast, strictly a bird of salt marsh, sometimes in adjacent brackish marsh. Pick a style below, and copy the text for your bibliography. It has a patchy distribution in salt marshes of the Pacific Coast, as well as inland around the salty waters of the Salton Sea. A close relative of the Clapper Rail of the Atlantic and Gulf Coasts, and was considered part of the same species until recently. Because ofthe proximity ofthe occupied habitat to the Project Mexican populations prefer brackish marshes, dominated by dense stands of tall salt cedar (Tamarix gallica ) with an understory of iodine bush (Allenrolfia occidentalis).

The key to maintaining or expanding the rail population is maintaining early growth stages of cattail marsh by creating shallow water areas. 2, pp. GoALS AND OBJECTIVES: 1. Publication Year 1993 Publication Date 1993. The "Yuma" Clapper Rail inhabits freshwater marsh along the lower Colorado River and nearby areas. Sand deposition from storms may destroy marsh grasses, and this can affect Clapper Rail populations. "Taxonomic Status of Certain Clapper Rails of Southwestern United States and Northwestern Mexico." to this occupied habitat; the anticipated 25-year life of the project; and the likelihood of dispersing Yuma clapper rails due to limited habitat availability at the Refuge,” that "incidental taking of a Yuma clapper rail is likely." Despite drastic habitat changes, the Colorado River delta supports four species of protected marsh birds: California Black Rail, Virginia Rail, Least Bittern and Yuma Clapper Rail. The Yuma clapper rail was listed as endangered in 1976 under the Endangered Species Preservation Act, based on its precariously small population size in the U.S. and the threats to the new marsh habitat from channelization and dredging of the river in Arizona and California. Requires wet substrate (mudflat, sandbar) with dense herbaceous or woody vegetation for nesting and foraging. Clapper Rails live in saltmarshes with extensive vegetation, which they use as refuges, especially at high tide. The flycatcher is approximately 5.75 inches (15 cm) long, and weighs approximately 0.4 oz (12 g).

The pond is a favorite nesting spot for the endangered Yuma clapper rail. The Yuma Clapper Rail (Rallus longirostris yumanensis) is a binationally protected marsh bird in northwestern Mexico and southwestern US. One hundred years ago clapper rails were common marsh dwellers. Yuma clapper rail and California black rail are considered priority species of concern in the LCR MSCP and goals for both species include the enhancement of existing habitat, restoration of unsuitable habitat, and the establishment of additional breeding locations on the LCR. then, an annual spring calling count survey has been conducted during the rail's nesting and breeding season. California’s three subspecies of Rallus longirostris become subspecies of Rallus obsoletus , which is given the English name Ridgway’s Rail. 282-290, 1993. Other suitable rail habitat, however, has been lost through dredging and channelization projects along the Colorado River, and the Salton Sea has become a wasteland itself, a site of major concern for environmentalists working to bring it back from the devastation of sewage drainage and a disappearing water table.

WILDL. Originally named Lake Cahuila after the Indians living in the area, the Salton Sea was first called the Salton Sink in 1892. In summary, 38 points remained the same for each of the three rounds of surveys (Appendix C). Studying the habitat of the Clapper Rail over a large portion of its range is important because habitat relationships found in local areas can differ substantially from those over much larg- er (regional) areas (Wiens 198 1). Protection and development of these wetlands for waterfowl management created habitat for the Yuma clapper rail. Therefore, that information is unavailable for most Encyclopedia.com content.

Small, dark-spotted cat with grayish to cinnamon shading above and white underparts. Most online reference entries and articles do not have page numbers. Esteros are also important reproduction and nesting sites for non-migratory species, including the federally protected Yuma Clapper Rails, Least Terns, and Snowy Plovers. The taxonomy for this species is confusing and still being determined. Yuma clapper rail will serve as Action Items for this management plan. The habitat area is defined by the Colorado River delta (Mexico), the Salton Sea (California), Topock Marsh (Arizona), and along the Gila River to near Tacna (Arizona).

The California black rail (Laterallus jamaicensis coturniculus) is another sensitive species of national management concern that occurs in this region. • Although suitable habitat for the Yuma clapper rail exists immediately adjacent to the Central A venue Bridge, the quality of the habitat has been degraded from recreational trails, human disturbances (e.g., trash and campfire rings), and traffic noise making the habitat likely unsuitable for the clapper rail. Critical habitat has not been designated. occupied by Yuma clapper rail have a higher percent cover of shallow water (Eddleman 1989). This change was recognized by the American Ornithological Society in 2014. These wetlands provide critical habitat to native wildlife, including the endangered Ridgway’s rail (formerly known as the Yuma clapper rail) and yellow-billed cuckoo. 57, no.

Density of emergent vegetation has also been reported as important habitat variablean although findings differ. The encouraging survey results led researchers to conclude that the population was possibly increasing due to stabilizing habitat conditions. Yuma clapper rail pictures! 1993). Encyclopedia.com. The number of responses to taped calls was approximately twice the figure for the three previous years (673 compared to 272-350 in 1987-89). Birds moved greater (P < 0.05) distances and used larger (P < 0.05) areas during winter. If rail populations respond positively to prescribed fires, the project will provide a proven method for restoring rail populations and rail habitat along the entire Lower Colorado River. Approximately 1/5 of the habitat remains flooded year round to maintain emergent vegetation for nesting habitat and a constant crayfish food supply for the Yuma clapper rail. They prefer mature stands of cattails and bulrushes along the margins of shallow ponds with stable water levels. Dams eliminated many backwaters and created new marshes and wetlands.
