nesting and by July 18 had young out of the nest. They disappeared by 

 the end of the first week in September. The Virginia's Warbler resembles 

 Vermivora r. rubricapilla in its habits, except that it frequents the bushes 

 instead of the high trees, and has a song almost exactly like that bird, in 

 the late summer they were found in family parties and could be located 

 usually by the sharp chipping notes of the adults. The brushy draws and 

 thickets of Chimney Gulch were a favorite resort with them but they were 

 more often heard than seen. 



83 Vermivora celata celata. Orange-crowned Warbler.— 

 Fairly common along Clear Creek from May 6 to May 16. Not noted 



during the fall. „ , 



84 Vermivora celata lutescens. Lutescent Warbler.— Found 

 in the spring from May 6 to May 16, and taken once on Lookout Mountain 

 Sept 19 The relative abundance of celata and lutescens cannot be gauged 

 from the meager series in the present collection. We have two of the 

 former and four of the latter, and of these all but one lutescens were taken 



'" 85 "" 'oendroica aestiva aestiva. Yellow Warbler.- Arrived by the 

 end of the first week in May and was noted along Clear Creek and m the 

 town of Golden all summer. During the spring migration a few were seen 

 in the small draws near the mouth of Chimney Gulch. Two adult males 

 taken agree closely with Kansas specimens. ^ , • , 



86 Dendroica coronata. Myrtle Warbler.- Found spanngly 

 along Clear Creek below Golden, from the first to the sixteenth of May. 

 None were seen in the foothills nor was the species noted durmg the fall. 

 87. Dendroica auduboni auduboni. Audubon s Warbler.- Ar- 

 rived about April 25 and was common until May 20 along Clear Creek 

 Only a few were seen in the foothills, though a female was taken on Lookout 

 Mountain as late as June 6. It was probably a stray here however as it is 

 doubtful if the bird breeds this low down. Durmg the faU it occurred 

 sparingly in the foothills from September 5 to October 10 but was not 

 observed in abundance at any time. 



88 Oporornis tolmiei. Macgillivray's Warbler.- First se^n on 

 the edge of the foothills May 16 and was common from the mouth of Chim- 

 ney Gulch up to seven thousand feet by May 23. They were very restless 

 and active and had a sharp chipping note besides the song. Th^y ^^^^ 

 fairly common all summer in this locality. The last one, a female, was 



'1r ^GeotWypiftrichas occidentalis. Western Yellow-throat.- 

 ■ Occasional along Clear Creek dunng the summer, but more common 

 further east in the plains country, where they arrived May 5. 



90 Icteria virens longicauda. Long-tailed Chat.- Sevei al noted 

 in a draw on South Table Mountain facing Clear Creek on August 1 and 

 one ttken. They were still in full song and as usual wei. very secretive.
