and yellow Warblers, Linnets, Mr. Goldfinches, Black-headed Grosbeak, Spotted Towhee, Chipping Sparrows and Song Sparrow. A little farther north we found Orioles, Wood Pigeons, Bluebirds, Calif. Jays, Anna Hummer, and at a stop about opposite Stego Leap a Dark Sparrow sang continuously from the top of a small Tree. From there on they were frequently seen. The Ash-throated Flycatcher was first seen there and continued to be fairly abundant the rest of the way. At the next stop east of Yountville we added the Warbling Vireo, House Wren, Mourning Dove, Black-throated Gray Warbler, Bush Tit, Great Catcher and a Spotted Towhee that sang an individual song of its own. At our lunch spot a little farther north on the edge of a dry creek, we saw Killdeer and an Audubon's Green Heron, and a little later Cassin Vireo. On Mt. St. Helena I heard the Calif. Purple Finch. Clematis was in bloom and we saw one Dogwood still in flower. After passing Middleton we began to see W. Kingbirds which were abundant in Lake County. At Butah Creek bridge we stopped to listen to the Chat and Layali Bunting's, and heard Cedar Warblers - May 10. Clear Lake - Log Cabin Tavern. All four kinds of Swallows were abundant: Cliff, Barn, Tree and Violet Green. We watched a Tree Swallow take a large fluffy feather into a hole on the underside of a branch. Orioles, Yellow Warblers, House Wrens, Blackbirds abundant near the Lake.
