ON SIX SPECIES OF BIRDS NEW TO THE FAUNA OF 

 ILLINOIS, WITH NOTES ON OTHER RARE ILLINOIS 

 BIRDS. 



BY ROBERT RIDGWAY. 



The already large list of Illinois birds is materially increased by 

 the addition of the following six species, which brings the number 

 up to 34G, not including several species of doubtful occurrence. 



1. Zonotrichia querula. Harris's Finch. — Under date of Decem- 

 ber 4, 1879, Mr. W. H. Garman, of the Illinois State Laboratory of Nat- 

 ural History, at Normal, writes as follows: "I desire to call your atten- 

 tion to the fact that there are in the collection of this Laboratory two 

 specimens of Zonotrichia querula taken by the writer, one in the spring of 

 1877, near Bloomington, Illinois, the other on the ]4th of November, 1879, 

 near this place, and in company Avith Z. leucoplirys." The species was 

 included by Mr. Nelson in his list of the birds of Northeastern Illinois, on 

 the strength of a specimen being taken at Racine, Wisconsin, by Dr. Hoy.
