Michael Perrone, a biologist for the Division of Environmental Services at the state Department of Water Resources, will kick off the new year with a Flyway Nights presentation Thursday, Jan. 2, on population shifts in bird species of the Yolo Bypass.
His talk will begin at 7 p.m. at the Yolo Bypass Wildlife Area headquarters, 45211 Chiles Road.
The use and management of the Yolo Bypass has changed significantly over the past 50 years, said a spokesman for the Yolo Basin Foundation, which sponsors the monthly talks. These changes have had an enormous effect on avian ecology in and around the bypass.
Perrone, co-author of “Checklist of the Birds of Yolo County,” will draw from his voluminous personal field notes and the historical record to chronicle changes in abundance, distribution and diversity. His presentation will cover a variety of species, such as Swainson’s hawks, snowy egrets, purple martins, black-necked stilts, hooded orioles and northern pygmy owls.
The Yolo Basin Foundation offers Flyway Nights talks at 7 p.m. on the first Thursday of the month from November through April. For more information, call 530-758-0530 or visit www.yolobasin.org.
