256 General Notes. [m^i 



this species was taken October 25, in the heavy timber along the river. The 

 sex was not determined. This is the only individual of this form I have 

 ever noted in this vicinity. 



Pandion haliaetus carolinensis. Osprey. — On September 20, while 

 wallving along the river I noted two of this species flying over the water. 

 After waiting on the bank for over an hour I secured one, an adult female. 

 The other one remained about the same place for several days and then 

 disappeared. — Ira N. Gabrielson, Marshalltown, Iowa. 



Two Species New to Colorado. — Recent investigations in the orni- 

 thological collections of the Colorado Museum of Natural History, have 

 revealed some interesting facts and important records heretofore un- 

 published. 



One of the most noteworthy of these is an adult specimen of the rare 

 Yellow Rail {Coturnicops noveboracensis) taken and identified as an imma- 

 ture Porzana Carolina by Mr. L. J. Hersey of this city. As the bird is 

 unquestionably fully adult, the 'immature' on the label is obviously an 

 error by Mr. Hersey. The specimen is in fairly good condition and appears 

 to be typical. It was taken at Barr, Colo., some time during July, 1906, 

 exact date not given, which would suggest the possibility of a breeding 

 record. 



I also desire to record a specimen of Sennett's Night-hawk {Chordeiles 

 virginianus sennetti) taken at Barr, Colo., Aug. 8, 1910, by Mr. Hersey. 

 The identity of this specimen was ascertained by Mr. H. C. Oberholser- 

 of the Bureau of Biological Survey, Washington, D. C. 



Both of these specimens form first records for their respective species in 

 Colorado, and, in the case of the rail, one of the few for the western United 

 States. — F. C. Lincoln, Denver, Colorado. 



Unusual Occurrences at Madison, Wis. — Toxostoma rufum- 



Brown Thrasher. — A specimen in normal condition was taken January 

 25. The stomach contained the skins and seeds of the wild grape. 



Passerherbulus lecontei. LeConte's Sparrow. — Three were seen 

 on October 12, and one collected. Another seen October 19. 



Hesperiphona vespertina vespertina. Evening Grosbeak. — Two 

 female birds were seen December 14. 



Porzana Carolina. Sora Rail. — On December 28 while walking 

 through a frozen marsh two Soras were seen running through the rushes. 

 One bird was caught and found to be minus the right wing. The extreme- 

 minimum temperature for December was 13° and mean minimum 25.9°;. 

 mean monthly temperature 32°. It is not extremely unusual for a few 

 Soras to remain until the marshes freeze, but this would seem to be a case 

 of unusual endurance. En passant Butler in 'Birds of Indiana' writing' 

 of this species says "they are very sensitive to cold." — A. William; 

 ScHORGER, Madison, Wis.
