ILLINOIS AUDUBON SOCIETY 17 



It can readily be seen that nesting records fairly representing the sev- 

 eral areas into which, through variations in climate, topography, plant life, 

 etc., the state of Illinois might be divided, would be very interesting for 

 purposes of comparison. Such records would show to what extent, for ex- 

 ample, certain western birds are extending their range eastward into 

 Illinois. 



The Invasion of New Areas. 



Elsewhere in this Bulletin under the head of Spring Migrating Records, 

 Mr. T. E. Musselman, reporting for Quincy, notes the appearance within 

 the Quincy area during the last three years of such typical western birds as 

 the white-headed woodpecker, the western grebe and the Harris' sparrow. 

 From Ogle and DeKalb counties come reports of the western meadowlark. 

 Here is an interesting lead to follow up. Observers in any part of Illinois 

 thus "invaded" can be sure of a welcome for reports of occurrences for this 

 season and past seasons and for nesting records of the above named birds. 

 Mr. Musselman will be invited to edit such data and he will doubtless wel- 

 come correspondence on that subject. 



Birds of central and southern Illinois that seem to be extending their 

 range northward might come in for particular attention at their north 

 limits. The cardinal grosbeak, for example, has been nesting for the past 

 three years at Highland Park, which is on a wooded ridge along Lake 

 Michigan, twenty-three miles north of Chicago. Prior to that time the 

 cardinal's "farthest north" was Riverside, Illinois, ten miles southwest of 

 Chicago, on the DesPlaines River, and it was only eight or ten years ago 

 that it was first recorded there. 



The tufted titmouse has apparently appeared for the first time within 

 the Chicago area during the last two years, observers reporting it from 

 Hinsdale, about sixteen miles southwest from Chicago. Observers likely 

 to be within the northward-tending range of the cardinal and the titmouse 

 or of the eastward advance of the western birds named above have a chance 

 to get honorable mention in mapping out the new habitats of these birds. 



Other birds might come in for mention here. Where are the north 

 limits of the mocking-bird? Of the red-bellied woodpecker? The 

 prothonotary warbler? Where does the yellow-headed blackbird nest in 

 Illinois? In Lake County in extreme northeastern part of the state, which 

 has many lakes with marshy margins, the yellow-heads return year after 

 year to nest only at Butler's Lake near Libertyville and, possibly, at Fox 

 Lake. (Gcelitz has an interesting article on the bird life of Butler's Lake 

 in the number of the Wilson Bulletin named above. Upon receipt of thirty 

 cents Professor Lynds Jones of Oberlin, Ohio, will send a copy to any 

 address.) Other birds might be referred to but enough has been said, 

 perhaps, to "start something." It is hoped that no one will hold back 

 his record because it is imperfect or incomplete. It will at least be sug- 

 gestive. Let the readers of the Autumn Bulletin have the benefit of it. 



For Those Who Feel and Thrill But Do Not Act. 



In an article on bird protection laws by Everett L. Millard to be found 

 in another part of this Bulletin it appears that there are seven game
