FIELD NOTES Doug Bell LOCATION: Sulphur Springs Mountain, St. Johns Mine, 1 mi. Q E Highway 80, Solano Co., Calif. DATE: 2 May 1987 TIME: 6:30 am - 8:30 pm Maren and I talked with some people in a room who were watching the cliffs. Turns out - some friends of theirs were hiking down from the rocks.

Some Violet-green Swallows and only a handful of White-throated Swifts. A Horned Owl was scared up from below the middle cliff. I elected to hike up the middle, to the east of the middle cliff.

On the Westernmost Cliff, which has a long S-E face, I saw a stick-nest situated in a cleft about 1/3 of the way down the rock, near its westernmost point (as viewed from the middle rock). The cleft is complete - one can look thru it just where the nest is located. The nest
