Unitt (1987) documented that the flycatcher had been extirpated, or virtually extirpated <br />(i.e., few territories remaining) from the Santa Clara River (Ventura County), Los Angeles River <br />(Los Angeles County), Santa Ana River (Orange and Riverside counties), San Diego River (San <br />Diego County), lower Colorado River (Imperial and Riverside counties and adjacent counties in <br />Arizona), Owen's River (Inyo County), and the Mohave River (San Bernardino County). Its <br />former abundance in California is evident from the 72 egg and nest sets collected in Los Angeles <br />County between 1890 and 1912, and from Herbert Brown's 34 nests and nine specimens taken in <br />June of 1902 from the Lower Colorado River near Yuma. <br /> <br />Survey and monitoring efforts since the late 1980s have confirmed the flycatcher's presence at a <br />minimum of II sites on 8 drainages in southern California, including the Colorado River. <br />Current known flycatcher breeding sites are restricted to coastal southern California from Santa <br />Barbara to San Diego, and California's Great Basin near the towns of Kernville, Bishop, <br />Victorville, the San Bernardino Mountains and along the lower Colorado River. The largest <br />populations exist along the San Luis Rey, Santa Margarita, Santa Ynez, Kern and Owen's Rivers. <br />Combining survey data for all sites surveyed since the late 1980s for a composite population <br />estimate, the total known flycatcher population in southern California is 95 territories, with <br />possibly as many as 178. <br /> <br />Texas Distribution and Abundance. The Rio Grande and Pecos River in western Texas <br />are considered the easternmost boundary for the flycatcher. Unitt (1987) found specimens from <br />four locations in Brewster, Hudspeth (Rio Grande), and Loving (Pecos River) Counties where <br />the subspecies is no longer believed to be present. Landowner permission to survey riparian <br />areas on private property has not been obtained; thus current, systematic survey data are not <br />available for Texas. There have been no other recent reports, anecdotal or incidental, of <br />flycatcher breeding attempts in the portion of western Texas where the subspecies occurred <br />historically. It is unknown at this time whether the flycatcher has been extirpated from Texas, <br />but it is unlikely that there are significant numbers. <br /> <br />Nevada Distribution and Abundance. Unitt (1987) documented three locations in Clark <br />County from which flycatchers had been found prior to, but not after 1970. In 1998, two pairs of <br />flycatchers were documented. Current survey efforts have documented breeding birds along the <br />Amargosa, Pahranagat, Muddy, and Virgin Rivers (McKernan and Braden 1997, 1998, 1999) in <br />southern Nevada. <br /> <br />In summary, more intensive and widespread surveys and monitoring efforts have documented the <br />presence of a greater number of flycatchers than known at the time oflisting. However, this does <br />not imply an increase in the actual population, or that the status of the species has remarkably <br />improved. Continuing losses of occupied habitats and degradation of other areas precludes the <br />possibility of population increases. Recovery actions may take many years to implement and <br />decades for habitat to be restored. Protection of occupied habitats as a consequence of section 7 <br />consultation does provide some stability for those populations, but the net result is still a <br />declining population. <br />
