THE CONDOR 
Vol. XVII 
tary Sandpipers ( Helodromas solitarius cinnamomeus ) were seen occasionally, 
and on August 23 a small flock of Pectoral Sandpipers ( Pisobia maculata ) was 
noted. Eared Grebes ( Colymbus nigricollis calif ornicus) appeared on the 
waters of the lake, and some of the song birds, notably the Western Tanager 
( Piranga ludoviciana) , had greatly decreased in numbers. 
On the last day of my stay at the station, August 25, another new bird was 
added to the Flathead list. A swift flew over the station building, and hovered 
about long enough to be identified as a Chactura. I did not see it closely 
enough to make sure of the species, but considering the locality there is little 
doubt but that it was Vaux Swift ( Cliaetura vauxi). This bird has been re- 
corded but once previously from Montana, when a bird was taken at Silver, 
Missoula County, June 25, 1891 (Bendire, Life Histories of North American 
Birds, vol. ii, 1895, p. 183). This is also in the western part of the state. Mon-

tana records of the Chimney Swift are equally rare and only from the extreme 
eastern part of the state. While visiting Mr. H. P. Stanford at his taxidermist 
shop at Kalispell the next day, he informed me that he had also seen swifts at 
Somers, at the north end of Flathead Lake, but did not know what kind they 
were. 
I obtained from Mr. Stanford several records of other birds that are new 
to Flathead Lake, most of which are represented in his collection of mounted 
birds from this region. He possesses two good specimens of the Western Grebe 
( Aechmophorus occidentalis ) which he states occurs regularly on Flathead 
Lake in September. There are no previously published records of this bird 
from Montana to my knowledge. He also has a specimen of the White-winged 
Scoter ( Oidemia deglandi), and stated that he has mounted for others at least 
three specimens of the Surf Scoter ( Oidemia persjncillata) , both species being
