<br />Soil Investigations for Data Collection in the Delta <br />Initial Study/Proposed Mitigated Negative Declaration 69 <br />nesting habitat exists. Therefore, American Peregrine Falcon has a low potential <br />to occur within the Study Area. No take of American Peregrine Falcon per <br />California Fish and Game Code Section 3511 would occur due to the Proposed <br />Project; however, CEQA considers potential effects beyond direct take of Fully <br />Protected species. Implementation of Mitigation Measures MM BIO-1 and MM <br />BIO-6 would reduce potential impacts to American Peregrine Falcon to: Less <br />than Significant with Mitigation Incorporated. <br /> <br />Loggerhead Shrike (Lanius ludovicianus) <br />The Loggerhead Shrike is a California Species of Special Concern and a <br />USFWS Bird of Conservation Concern. Loggerhead Shrike is a medium-sized <br />passerine with gray plumage and a black mask around the eyes and forehead <br />(Yosef 1996). This species is found throughout North America and is a common <br />resident and winter visitor in lowlands and foothills in California. Loggerhead <br />Shrikes use a variety of open grasslands across their range, including <br />grasslands, desert scrub, shrub-steppe, open savannah, irrigated pasture, grain <br />and hay crops, and alkali seasonal wetland (Yosef 1996, Pandolfino and Smith <br />2011). Loggerhead Shrikes nest in shrubs and trees surrounded by open habitat. <br />Breeding occurs from March through July (CDFW 1990e). <br />Loggerhead Shrike has a high potential to occur within the Study Area due to the <br />presence of suitable habitat and several recorded occurrences near Impact <br />Areas. implementation of Mitigation Measures MM AES-1, MM BIO-1 and MM <br />BIO-8 would reduce potential impacts to Loggerhead Shrike to: Less than <br />Significant with Mitigation Incorporated. <br /> <br />California Black Rail (Laterallus jamaicensis coturniculus) <br />California Black Rail is listed as Threatened under CESA, Fully Protected under <br />California Fish and Game Code, and is a USFWS bird of conservation concern. <br />California Black Rail is a small-sized rail with mostly dark gray feathers, a small <br />black bill, red eyes, white-speckled back, belly, and flanks, and chestnut colored <br />nape and upper back. Approximately 80% of the California Black Rail subspecies <br />resides in the San Francisco Bay estuary (Evens et al. 1991), with other <br />populations in the Sacramento-San Joaquin Delta, coastal southern California at <br />Morro Bay, and a few inland locations (Eddleman et al. 1994). The species most <br />commonly occurs in tidal brackish or freshwater emergent wetlands dominated <br />by pickleweed and bulrush and occurs in non-tidal freshwater marsh habitat as <br />well as in immediate vicinity of tidal sloughs. Black rail inhabits shallow and high <br />elevation areas of densely-vegetated wetlands where it consumes a variety of <br />small terrestrial invertebrates. Nests are completely concealed by vegetation in <br />high portions of tidal marshes, shallow freshwater marshes, wet meadows, and <br />flooded grassy vegetation (Eddleman et al. 1994). Breeding occurs from mid- <br />March through June (CDFW 1999e).
