Prairie Warbler
Dendroica discolor
Sept.3 Monterey area, Monterey Co., Calif.: 1 - Washington Park, Pacific Grove where it was found by others yesterday. We located the bird with a mixed species feeding flock of warblers, vireos,
and parids. The Prairie foraged slowly and deliberately
in live oak foliage within 20' of the ground. The call note
was a soft 'seep' like Townsend's. Upperparts were a dull
greenish; wings with 2 obscure pale wingbars; underparts
(not entire throat)
mostly yellow but chin and undertail coverts white; eyebrow
and sub-ocular line yellow; line between throat and subocular
yellow grey-black; dark streaks and spots along sides
and flanks; wagged tail; smaller (slightly) than Townsend's
Warbler. This bird looked intermediate between the illustrations
(in Robbins et al Birds of North America) of imm ♀ and ♀
adult on p. 269: the throat wasn't as extensively white
as the imm.♀ and the face and flank markings were more
distinct, but not as distinct as shown for the ad. ♀.
Sept.5 Point Reyes, Marin Co., Calif.: 1 imm.♀ at Drane's Beach
in willows and shrubs and on hillsides between the
cypresses and the pond where it had first been seen Sept.2.
A small warbler (smaller than accompanying Orange-crowned)
with white tail spots; wagging tail; obscure wingbars; greenish
back and head tised slightly rusty on back; pale superciliary
and subocular stripe; whitish-yellow throat; yellow underparts
with dusky, broad streaks and flanks.
