Worm-eating Warbler
Helmitheros vermivorus
July 17 Tilden Park, Contra Costa Co., Calif.: I seen in dense
willow-dogwood thickets about 200 yds. s. of Jewel
Lake opposite Nature Center where found on July 11
by Phil Gordon. Today, Linda Hale saw it at about
1030 about 20-30 yds into the thicket from the road at
a spot where it had been seen most often the last three days;
she came out to get me, and meanwhile Nancy Conzett,
after being there for only 5 minutes, had the bird at close
range in the same area at ~1045. Then we went back
into the thickets and at about 1115, I heard a warbler
chip note, about 20 yds. N. of the spot where Linda had
seen it, which sounded like a weak or soft Yellow Warbler
note, and glimpsed the bird low in the undergrowth. After 10
minutes or so, the Worm-eating Warbler came into view,
and we watched it intermittently for about 20 seconds
at about 30 ft.' Then we lost it, but it re-appeared a
few minutes later, higher in the foliage, and we saw it
again for about 10 seconds in fairly bright light.
This warbler was very long-billed and short-tailed relative
to other warblers. The wings and back were a dull brown
without streaks or wingbars. The head was conspicuously
marked - a blackish streak through eye and along side of
crown - thus the center of the crown had a broad, pale streak
bordered on either side by a well-defined blackish streak. The
underparts appeared to be a pale buffy, looking almost dull
golden yellow when in the sunny foliage.
