ivare at Baird, where I obtained only a single s[)ecimcn. In August 

 the}' were rather eominon among the bushes about the margin of Castle 

 Lake, 1*0 miles west of JNlouut Shasta., associating with the Pileolated 

 Warblers [Sijlcania pileolata), which were equally common. 



A little later some were found on the highest timber-line of Shasta, 

 w !nM<' a few young birds also were seen.

Probal)ly raic as I have but one specimen, which was taken at the 

 t iiiibei -]iiu> of Shasta.

A bird api)arently as common as in the Eastern States. It arrived 

 at 1> 111- 1 al) )ut May 1, where it was abundant uutil midsummer, when 

 its numbers greatly diminished. Three nests were found in the bushes 

 by the river, t-.vo o:i May 2-9, one on June 10.

A number of specimens from Ked Bluft", which I at first took to be

 timber belts about May 1 aiul at Humbohlt Bay in the fall. 



Dendroica aiiduboiJ. ;Ti)\vus.). Andiihon'' n Warhlcr. 



Although 1 was in the foot-hills of Shasta County from April 1 to 

 July 1, ISS.J, I did not find this species itntil I ascended Mount Shasta 

 in August. It was the commonest species of Warbler immediately below 

 the timber-line, the bulk of these being young birds. On March 29 of 

 the following year they arrived at Ked Bluff, where they were rather 

 common during the spring. 



Dendroica nigrescens (Towns.). Blaolc-ihroalcd Gran Jl'arbhr. 



Quite common in the foot-hills along the Lower McCloud Biver. It 

 was first seen at Baird May 10, and at Bed Bluti' the following spring 

 on May G. At the latter place, however, it was \'ery rare, aud was 

 totally wanting in the heavy pine regions al)0ut Mounts Shasta and 

 Lassen.
