Remsen, J.V. 1977 Red-eyed Vireo Vireo olivaceus June 14 Pt. Reyes, Marin Co., Calif.: 3 (!!): 1 in myrtle patch just N. of Fish Docks; 2 in 2 different gullies in poison-hemlock just SW of Nunes Ranch. The bird near Fish Docks and one of the Nunes birds looked identical: solid blue-gray crown bordered by wide dark eyebrows eyelines; pale eyelines broad and conspicuous; irises red (seen clearly); cheek dull olive; underparts immaculate white; backs gray, about same color of Warbling Vireo; bills heavy, heavier looking than Warbling Vireo; large body size, noticeably larger than Warbling. We were certain these two birds were different because other birders (Bud Fry et. al) were looking at the bird we had found at Fish Docks while we were seeing the bird at Nunes. The third bird looked different - its back was definitely more greenish and it had more greenish-olive on the cheeks, neck, and sides of breast [head pattern and underparts same]; we did not see the red iris on the third bird. June 23 East Mojave Desert, San Bernardino Co., Calif.: at Fort Piute 1 singing in willow riparian - phrases much richer, sweeter, prolonged, and more variable than Solitary. Seen only for ~ 2 seconds but gray crown bordered (no wingbars) by dark stripes; uniform gray-green upperparts, and uniform grayish-white underparts clearly noted and song totally different from Warbling.
