184 Smith, Notes on Colorado Birds. [April 



rando:m notes on the distribution of so.me 



COLORADO birds, WITH ADDITIONS TO THE 

 STATE AVIFAUNA. 



BY TIORACE G. SMITH. ^ 



Since the publication of Prof. W. W. Cooke's 'Birds of Colorado* 

 some additional information has been obtained relative to the dis- 

 tribution and breeding habits of some species whose range at that 

 time was but little known, so far as the State of Colorado was con- 

 cerned. 



Through connection with the State Historical and Natural His- 

 tory Society, the writer has had opportunities, both to collect and 

 examine a number of specimens from various localities within the 

 State, and presumes the following notes will be of interest to bird 

 students at this time. Unless otherwise stated, the specimens 

 referred to were donated to the museum by the persons whose 

 names appear in connection with the information given. Others 

 were taken by Curator William C. Ferril and the writer, while on 

 short collecting trips, and in this connection it may be well to state 

 that usually but one to three days were spent in any one locality. 

 Had time been available for more continuous and thorough work, 

 additional facts would doubtless have been secured. My thanks 

 are due Prof. Robert Ridgway of the National ^Museum, also to 

 members of the staff of the Biological Survey, who kindly examined 

 some of the more difficult subspecies. 



Harelda hyemalis. Old-squaw. — Three more specimens, now in the 

 State collection, may be recorded for the State. One was shot at Love- 

 land, Colo., Oct. 16, 1898; another at Calkins Lake, near Longmont, Oct. 

 23, of the same year. Both were probably males and were taken by Mr. 

 Bryan Haywood. A later specimen, a male, was secured by Judge Park, 

 at Longmont, about Nov. 20, 1903. 



Oidemia deglandi. White-winged Scoter. — A male was taken at 

 La Salle, Weld Co., Oct. 24, 1904, and presented to the museum by Mr. 

 H. G. Clark. 



Oidemia perspicillata. Surf Scoter. — Two specimens, both males, 



'Assistant Curator, State Historical and Natural History Society, Denver, Col- 

 orado.
