52 RIDGWAY ORNITHOLOGIGAL CLUB. 



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

 but little, even in a strong wind. 



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. Helminthophila. ruficapilla gutturalis Ridgw. 

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

 only 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;* Dekdroioa iEOTiVA (Gmcl. ). (Fellow Warbler). Com- 

 mon everywhere. 



105. Dendroica auduboni (Towns.). (Audubon'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 

 in the coast region. 



106. 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). (Towns end" 1 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 (Aud.). (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 

 Vellowthroat) This species is not common in Cohuilla Valley; 

 three specimens were taken here and one at Banning.
