Siskiyou County Tri-Color Black Birds

Outside of the town of Yreka on Oberlin Road (#4721) heading east, you'll find a blackbarry patch in field 30 feet from the fence line, there are nesting Tri-Color Black Birds using the blackbarry patch. I have heard this area has had Bank Swallow colonies in past years.I didn't find any Bank Swallows. Rich Cimino, Alameda County
