JAN., 1909. BIRDS OF ILLINOIS AND WISCONSIN CORY. 



405 



Length, 6.85; wing, 4.95; tarsus, .95; bill, .95. 



This species is not common, occurring irrregularly in Wisconsin 

 and Illinois during the migrations. 



Mr. T. M. Woodruff considers it "a very rare migrant" in the 

 Chicago area and states he has taken it at Meredosia, Illinois. (Birds 

 of Chicago Area, 1907, p. 69.) Nelson procured a specimen and saw 

 a number of others on the Lake shore near Waukegan, 111., on June 

 9, 1876; he also states that Mr. R. P. Clarke had taken it late in 

 the autumn near Chicago. (Birds of N. E. Illinois, 1876, p. 127.) 



Messrs. Kumlien and Hollister give it as occuring regularly in 

 Wisconsin but by no means abundant. They say : " Small flocks of 

 a dozen or less are sometimes found about Lake Koshkonong until 

 the middle of June, and they are back again with barely full-fledged 

 young by August i." (Birds of Wisconsin, 1903, p. 46.)
