IV. Appendix <br /> Comments on Bird Soecles list from Appendix A of 212 <br /> tunnlemental Biotics StUdy <br /> Great Blue Heron & Great Egret -We know of no rookeries on the property. They <br /> do visit the site to forage. <br /> Blue-winged Teal - This is a rare spring migrant in the Central Valley. It is <br /> extremely rare in fall and winter. <br /> Cooper's Hawk- A common winter resident in the valley, but a rare breeder. <br /> Since the species is one of special concern (in its nesting habitat), it is critical that <br /> nesting Is confirmed not speculated. The Biotics Study indicates that it nests on <br /> the property. Where is the evidence? <br /> Northern Harrier-Although several were seen on the property, no nesting was <br /> mentioned in the Biotics Report, yet the species is listed as breeding on the site. <br /> The overgrazed condition of the property and lack of substantial nesting structure <br /> would indicate the ranch Is not suitable for nesting harriers. The species is <br /> migratory in the valley, with an Influx of northern breeders during the winter <br /> D86 months. <br /> Common Snipe - This species is a winter visitor to the Central Valley. It <br /> probably does not nest east of the Sierra Escarpment. <br /> Black-necked Stilt - A resident species that nests in wetland systems In the <br /> Central Valley. Listed as a winter migrant only. <br /> American Avocet - A summer resident that breeds in Central Valley wetlands. <br /> Again,we suspect this species does not breed on the site, but instead fed in <br /> seasonal marsh habitat. <br /> Spotted Sandpiper- A winter visitor only nesting along montane streams. Does <br /> not nest In the valley. <br /> Western Screech (awl - Rare in the valley floor. The Biotics Study implies that <br /> nesting binds were found. This seems unlikely, unless surveys were conducted <br /> at night. <br /> Hairy Woodpecker- A montane species that Is extremely rare In the Sacramento <br /> Valley. Breeds in transition through subalpine life zones. <br /> Western Wood Pewee - A summer visitor and migrant. We know of one nesting <br /> pair on the Cosumnes River Preserve. Other pairs are recorded from the <br /> Cosumnes River near Hwy. 99. This rare (on the valley floor) species may nest <br /> on Buckeye Ranch, but would require confirmation of nesting. <br /> S <br /> VI-88 <br />
