97 where me had lunch Then N.E. toward Seattle then S.E. through Indian Springs to Las Vegas. Saw a small bird on top of a low brush in one place on the N.E. road. As we neared Las Vegas I saw a large hawk perched in a Cottonwood tree on a ranch - I took it to be a Fer. Roughley. It showed a white tail and very light (white?) underparts when it flew. Desert all the way. Where there were springs there were mesquite trees and as we neared Las Vegas we saw stunted tree yuccas. Cloudy - After dinner we drove over to Boulder Dam - Illuminated and men working on the power houses. Jan. 14: In walking about Boulder City I saw many Eng. Sparrows, a few Brewer Blackbirds and an Audubon Warbler. After breakfast we met Roy Hillisand and his party at the Administration Bldg. for the trip to Boulder Dam. While waiting I saw a few juncos, a robin, a few Audubon- Warblers and Gambel (?) Sparrows. At the dam I noticed from the road on the dam English Sparrows. Also heard a song which sounded like a Canyon Wren. It was on the cliff below the dam - Later when we went to the bottom of the dam I saw a tiny bird which alighted on the face of the cliff and acted like the Canyon Wren. On the return trip to Boulder City I saw a hawk alight on the top of a peak. It suggested the Prairie Falcon - After lunch we drove back to Barstow (182 mi) - Saw a few Crows (Laws) along the way and after we crossed the Calif line one Shrike - Beautiful sunset as we drove from Barstow to Yermo. Wonderful Cactus gardens on Mt. Pass, slender East of Baker. Also small trees with long pods (6-8 in) Desert Willow (a catalpa), Spent the night at Barstow.
