Remsen, J.V. 1977 Grace's Warbler Dendroica graciae May 21 Clark Mountain, San Bernardino Co. Calif.: As we were leaving the white fir path, I heard a strange warbler song and tracked it down to a singing male Grace's Warbler. Six of us got good views as it sang from the tops of pinyons for several minutes. The rest of the group had already moved several hundred yards downhill and by the time they raced back up hill, it had moved off several hundred yards. But luckily it then moved back downhill 200 yds below the original sighting, where it remained for 10-15 minutes and everybody got to see it extremely well. This bird would sing consistently from one or two trees for 5-10 minutes, then move long distances and then begin singing again, as if hunting for a mate. It was not on a fixed territory, as we last saw it 1/4 mile downhill from the original point on pinyon-covered hillside. This bird was among pinyons exclusively - not white firs. The song was a (10-12) rapid series of "sweet" notes, rising in pitch at the end. Description: size and shape of nearby Black-throated Gray Warbler; upperparts all blue-gray with dark streaks on back; two prominent white wingbars; conspicuous yellow eyebrow extending behind eye; cheeks, lores blue-gray; throat and breast bright yellow; belly white with conspicuous dark streaks on lower sides and flanks; tail without conspicuous marks - (paler gray) some paleness along outer rectrices. or tail spots They all yellow eyebrow, and absence of white neck patch eliminates Yellow-throated Warbler. The yellow eyebrow and yellow breast eliminates Audubon's Warbler.
