Please print or type Species Ovenbird Location railroad station at Kielse County San Bernardino State Calif Elevation Observer Van Remsen Number of birds 1 Time of Day Light conditions shade but still off Distance to bird 40' Optical equipment 10x50 binocs Length of time observed 30 seconds Sex Unknown Plumage (e.g. Breeding) adult? immature? not certain (orange seemed bright enough for adult, but not extensive enough) Overall appearance and relative size: When first flushed, I called it as either a Hyllocichla thrush or an Ovenbird. When perched, it was obviously too small to be a thrush - size of sparrow. Bill: Thin and pointed. Seemed thicker at base than most warbler bills Crown and forehead: rusty orange streak down center of brown crown. There was not a strong dark border as illustrated in Peterson's F.G. to W. Birds - just a trace of a border around the orange Nape: brown - orange didn't seem to come down that far. Face: seemed solid brown except for a very conspicuous white eye-ring Eye: dark Throat: whitish with a dark whistler on either side composed of small dark spots Breast and sides: very bright clean white which highlighted the sharply defined oval spots which proceeded down the breast in rows Belly and flanks: mostly pure white - some very faint small spots on flanks Undertail coverts: white Back: Uniform brown Wings: Uniform brown Underwings: Not seen Rump: Brown Uppertail coverts: Brown
