52 RIDGWAV OKNITHOI.OGIGAL CLUB. 



was built was so stiff and matted together that it could have moved 

 but little, even in a strong w^ind. 



It is a rare bird in Southern California so far as my experience 

 goes and from its inhabiting such thick brush is very hard to get at. 



102. Helmintiiophila ruficapilla gutturalis Ridgw. 

 {^Calaveras Warbler). This is a very rare species with us, I have 

 oiily taken one specimen prior to this year when I was fortunate 

 enough to obtain three males in the Cohuilla Valley on April 9th., 

 1 2th., and 14th., respectively. It seems strange to me that this 

 species is wanting in the interior. 



103. Helminthophila celata lutescens (Ridgw.). [Lu- 

 tescent Warbler'). This species is not uncommon in the Cohuilla 

 Valley during the migrations. Five specimens were taken between 

 April 1st. and 12th. I have no record of its occurrence at Yuma. 

 A young $ was taken in Bear Valley June 25th. 



104?*^ DE?JDnoioA jeotiva (Gmel.) . (^Tellow Warbler). Com- 

 mon everywhere. 



105. Dendroica auduboni (Towns.). {Auduboti's Warbler). 

 Quite abundant in the Cohuilla Valley where they are Winter resi- 

 dents in small numbers. Not uncommon at Bear Valley. A ? 

 taken at the latter place June 19th. had a feather in her mouth, and, 

 as she was hopping about the ground, I suppose she was in search 

 of other materials for a nest. Her abdomen contained a mass of 

 tape-worms that would equal one of her eggs in bulk. A few 

 breed in the high mountains. They are common Winter residents 

 \\\ the coast region. 



io5. Dendroica nigrescens (Towns.). {Black Throated 

 Gray Warbler). Probably only a migrant in the Colorado Desert. 

 They breed not uncommonly in Bear Valley where several, both 

 adults and young were taken in June. 



107. Dendroica townsendi (Nutt.). {Townsend''s Warbler). 

 Rare. Only three were seen. These were taken at Yuma May 

 13th. They were excessively fat. The species is a rare migrant 

 in Southern California. 



108. Geothlypis macgillivrayi (And.). {Macgillivray^s 

 Warbler). ^ Not uncommon in Cohuilla Valley and at Yuma. None 



were noted elsewhere although they occur at San Bernardino and 

 probably in Bear Valley. 



109. Geothlypis trichas occidentalis Brewst. ( Western 

 Tellowthroat) This species is not common in Cohuilla Valley; 

 three specimens were taken here and one at Banning.
