Yuma clapper rail occupies habitat directly adjacent to the Project site, no suitable habitat occurs within the Project boundaries, therefore no direct impacts will occur. The flycatcher is approximately 5.75 inches (15 cm) long, and weighs approximately 0.4 oz (12 g). Though weighing a mere 10 ounces, the clapper rail can grow up to 14.5 inches long and sport a 19-inch wingspan. 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. Clapper Rails live in saltmarshes with extensive vegetation, which they use as refuges, especially at high tide. Encyclopedia.com. More In the early 1800s, California clapper rails (Rallus longirostris obsoletus) were abundant in the tidal marshes of San Francisco Bay and smaller populations were present in coastal marshes from Humboldt Bay to Morro Bay. Anderson and Ohmart (1985) fo und that Yuma clapper rail typically reached The Salton Sea, California's largest inland lake, was created in 1905 when the Colorado River overflowed its banks into Imperial Valley.

Hanebury Abundance, distribution, and habitat use of Yuma clapper rails (Rallus longirostris yumanensis) in the Colorado River Delta,Mexico Abundance, distribution, and habitat use of Yuma clapper rails (Rallus longirostris yumanensis) in the Colorado River Delta,Mexico The Yuma clapper rail has been sighted along the Colorado River where Nevada, Arizona, and California meet, south to Yuma, Arizona, and into Mexico. These riparian habitats are associated with rivers, wetlands, lakes, and reservoirs. The Yuma subspecies, which averages 14-16.5 in (36-42 cm) in length, is gray-brown with a tawny breast, a white throat and undertail, and bars across the flanks. Two types of nests have been found: one of sticks and dead leaves, another of finer stems with dry blossoms still intact. The primary threats to the Yuma clapper rail are habitat loss and degradation due to changes in historical hydrographs, channelization, and diversion of river flows for agricultural and municipal purposes. Located in the Yuma Desert in Arizona, YCNHA contains over 1,500 acres of previous freshwater wetlands along the Colorado River. 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, clearing the way for First Solar to build the Sunshine Valley Solar project next to one of the bird's few remaining strongholds. The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae. Repr…, Desert Tortoise 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. Conduct a rail census of all habitat areas, including the Colorado River delta in Mexico and the Imperial Valley, every three years. Displaying 1 - 5 of 5 datapoints. Because ofthe proximity ofthe occupied habitat to the Project 2, pp. 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. Habitat: Emergent freshwater and brackish-water riverine wetlands exposed to pe- riodic flooding (Todd 1986). • 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. ], vol.

Yuma Ridgway's Rail. 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. Estimates of abundance of Yuma clapper rails in the Cienegra de Santa Clara, 1999-2000 42 APPENDIX B Table I. Mexican populations prefer brackish marshes, dominated by dense stands of tall salt cedar (Tamarix gallica ) with an understory of iodine bush (Allenrolfia occidentalis). In the United States, Yuma clapper rails nest in freshwater marshes. . Hace cien años los rascones palmoteadores eran comunes habitantes de los pantanos. Moffitt, J.

Operations and maintenance actions by BOR must result in no net loss of Yuma clapper rail habitat, otherwise rails will be taken due to loss of nesting habitat. Gopherus agassizii The clapper rail is mainly a saltwater bird, and its preferred habitat is coastal saltwater marshes and mangrove swamps. Others have suggested that fire might also be an effective management tool to improve habitat conditions for California black rail (Repking 1975). 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. 2 0 obj<> Items per page .

The Yuma Clapper Rail (Rallus longirostris yumanensis), restricted to the lower Colorado River drainage system and the Salton Sea in the Imperial Valley of California, is considered These birds prefer low portions of coastal wetlands dominated by cordgrass (spartina), pickleweed, mangroves, and other vegetation. In 1990, the U. S. Fish and Wildlife Service, the U. S. Bureau of Land Management, the U. S. Bureau of Reclamation, the Arizona Game and Fish Department, the California Department of Fish and Game, and local National Audubon Society chapters participated in the calling count survey along the Colorado River and in the other isolated areas where the rail is known to occur. ��Y)q�%���v_Z�d�26�3e��K ��Zv�x׊�]�cu�ܚ}X�J�0EJ�������'@��5�������1>ۆ1�c��Ěٺ:h\����-@!��ߊu���I��`��G�|�f����u ;9އ��V�ى��{l{�A�ݝ�H�U]MБXW����lN���rkF"��(�.�)��DL����v�釜8�}�θ�=�I�oD�:��~��1�8���̴+��2)��V�yi\���M��E�vW�o/��S����)$D��W��p�H⫒����������l��^����)��辁���810�݂캝��2߅"�S��Ц��Yݞ�@����4τj6�3��r����^��5�Z��/�E���2�~h_��*�֥ǦRWs�(KDiq�Q�Y�lq��z��‘����/�g�戻鶦=��ww�Ҿ�;^�x���КV���V�v�w��\ �e��M��m���`U��`%�L`�zv�aY�.��z��UhR��O?����ޚ�"�o�:�˭p���b�?ϲ�m۩���v7B�D/E :�w�������l�����묘p��|�!���T�N�c�(�V��L+�OJp�^;Y� �"1̚g�]9�`ݾ�'tM�[��`�&A��@��;q��f�Ձ��n6;Yٷ�*��j�D���Z���X��t��B'���}nb�X�&��o'Z��cS��5��$�n�նy����Uq��M��`�jy�Qa\=Ҝb�ݝ.-8�u�ƌ���5���p~zs!�w4 Brackish marsh vegetation in northern San Francisco Bay and Suisun Bay is similar in structure to habitats used by the Yuma clapper rail (R. l. yumanesis; Harvey 1980, Conway et al.

Little is known of Yuma clapper rail breeding and nesting. They prefer mature stands of cattails and bulrushes along the margins of shallow ponds with stable water levels. It uses its formidable bill to probe into muddy wetlands for invertebrate prey. The 2014 letter states that because of the Sunshine Valley Solar project's "proximity . They prefer mature stands of cattails and bulrushes along the margins of shallow ponds with stable water levels. ." Seasonal changes in Yuma clapper rail vocalization rate and habitat use. They can be found along rivers in freshwater marshes. In general, western clapper rails range from northern California along the Pacific coast to central Mexico. Subspecies yumanensis (ST) was called “Yuma Clapper Rail.” Modifying it to “Yuma Ridgway’s Rail” seems awkward, but could work. Small, dark-spotted cat with grayish to cinnamon shading above and white underparts. 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).

This change was recognized by the American Ornithological Society in 2014. Dams eliminated many backwaters and created new marshes and wetlands. The taxonomy for this species is confusing and still being determined. then, an annual spring calling count survey has been conducted during the rail's nesting and breeding season. 1 0 obj <>stream Basic facts about Clapper Rail: lifespan, distribution and habitat map, lifestyle and social behavior, mating habits, diet and nutrition, population size and status. Eventually, a mat of dead cattails forms in the shallows, providing nesting cover for rails. Over the next 40 years, Yuma clapper rails were found more and more frequently on the Colorado River in Arizona and California. "Yuma Clapper Rail Yuma clapper rail habitat (Table 1), which in 2010 approximated 914.14 acres, resulting in 49 call stations. The snail darter, Percina tanasi, is a small, robust fish, rarely exceeding 3.4 in (9 cm) in length. The Yuma clapper rail is the largest rail found along the lower Colorado River. Banks, R. C., and R. E. Tomlinson. "Yuma Clapper Rail Habitat Distribution and Habitat: The Yuma clapper rail is a marsh bird found in dense cattail or cattail-bulrush marshes along the lower Colorado River in Mexico north to the lower Muddy River and Virgin River in Utah above those rivers’ confluence with Lake Mead. Implementation of this conservation measure would maintain existing habitat at Topock Marsh for the Yuma clapper rail, southwestern willow flycatcher, Colorado River cotton rat, western least bittern, California black rail, yellow-billed cuckoo, gilded flicker, vermilion flycatcher, Arizona Bell's vireo, and Sonoran yellow warbler. ."

It lives in saltwater marshes, freshwater marshes, and mangrove swamps in California, Arizona, Nevada, and coastal western Mexico. The Ridgway's rail (formerly the California clapper rail) and the mangrove rail have been recently split. 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. Most of the U. S. population remains on its breeding grounds from mid-April to mid-September. The "Yuma" Clapper Rail inhabits freshwater marsh along the lower Colorado River and nearby areas. 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. A subspecies of the more widespread clapper rail, numbers of the Yuma clapper rail (Rallus longirostris yumanensis) have declined significantly since then as a result of depletion of its freshwater marsh habitat along the river.
