March 18th, Bill Williams Canon continued: Violet-green Swallow - few were seen. Rough-winged Swallows - many seen all day except possibly at the noon period. Woodhouse Jay - just one was heard calling (by Gale Monson). Raven - 2 flew over low. Verdin - Many old nests were found. Many birds calling with 2-3 different calls all day. Had good look at a few of them. Yellow showed well on head. Chestnut on shoulder. Their call notes mixed me up as much as the Hutton's Vireo here in the Willamette Valley. House Wren - few seen and heard. Baird's (Bewick) Wren - a few in the brush. Cactus Wren - 1 seen and heard - an awful buzzing and gargling note. Marsh Wren - 2 or 3 seen. 1 in brush clump on mud flats. W. Mockingbird - a few were singing - sound like Yellow-breasted Chat. Sage Thrasher - calls like a Long-tailed Chat, too. Had only a brief glimpse. Robin - a couple Plumeous Gnatcatcher - several singing and seen working in brush. 1 pair were attempting mating, while I watched. Ruby-crowned Kinglet - several seen and heard. Pipits - 25 seen on the flats Phainopepla - M & F seen frequently. Call notes plain. Perched in tops of trees usually. Both hang close together. Watched them feeding primarily on mistletoe (Phor. californicum) berries which are abundant now, and seemingly all thru the year. Bell's Vireo - 7 seen and heard. A rather low melodious serious note. Faint wing bars, and a light eye-ring. Lucy Warbler - 8 seen and heard. White below. Orange on crown and rump. A loud clear call from the brush. Audubon Warblers - quite a few Pileolated Warbler - one male seen and heard. This is the 1st arrival for the year in this area. Sonora Redwing - quite a few seen - more males than females. Common Dwarf Cowbird - 1 on snag near the ground in the mud flat area. House Finch - quite a few seen. Common Goldfinch - 1 male Abert's Towhee - a couple of small groups in the brush. Quite a variety of calls were given, and they were hard to see. Reminded me of the C. Babblers in India Nevada Savannah Sparrows - 6 or more. Gambell Sparrow - 3 or more. Song Sparrows - 6.
