F. Richardson 1937 North of 20-mile Creek, 9 mi. S Adel, Lake C., Oregon May 27, 1937 - The morning, from 4 - 8:30 A.M. was spent in observing and collecting birds in the extensive area of high sagebrush (dominant) at the broad mouth of the canyon, perhaps best considered part of Warner Valley proper. That this is a definite habitat for certain species is attested by the finding here of birds not seen in other regions (as buck-tit, cliffing Sparrow, Mallards (nesting)). It seems to approach the ideal habitat for other species (as quail, Yellow-throats, clots, Lapuli Buntings) which are here very common while less common or rare in habitats in the canyon itself. Data on breeding birds may be summarized: Becoming paired: Mourning Dove, Building nests: Brewer Sparrow, Yellow-throat, Robin With eggs: Mallard, Calif. Jay, Calif. Quail, Brewer Blackbird With young: Long-eared Owl, House Wren Additions to Birds Identified (see p. 3) Cliffing Sparrow Linnel Petalos Duck Long-tailed Chat Shoveler Duck Tornie Warbler a white-crowned Sparrow Plumbeous Bunch-tit Steller Jay Titmouse
