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 The increase also is attributed to additional areas being surveyed and more time being invested in the survey. It is thought that the Yuma clapper rail was not distributed along the Colorado River until suitable habitat was created through dam construction. Regulated water releases in the lower Colorado River slowed currents enough to allow sedimentation, which in turn allowed cattail and bulrush marshes to emerge. 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. © 2019 Encyclopedia.com | All rights reserved. As new habitat developed upstream, the rails moved in. 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). The immediate goal of the proposed project is to provide a tested and proven technique for creating/restoring optimal habitat for both Yuma Clapper Rails and California Black Rails. 69 POPULATION TRENDS OF YUMA CLAPPER RAILS IN THE COLORADO RIVER DELTA, MEXICO OSVEL HINOJOSA-HUERTA, JUAN JOSÉ RIVERA-DÍAZ, HELENA ITURRIBARRÍA-ROJAS, ALEJANDRA CALVO-FONSECA Abstract.

The Salton Sea, California's largest inland lake, was created in 1905 when the Colorado River overflowed its banks into Imperial Valley. The pond is a favorite nesting spot for the endangered Yuma clapper rail. The Yuma clapper rail is one of seven North American subspecies of the clapper rail, which is a large, long-billed, henlike marsh bird. Yuma clapper rail habitat tends to consist primarily of freshwater or brackish marshlands and riparian areas (Grinnell and Miller 1944). The rails then migrate south to Mexico for the winter.
