The only water birds on my list are those which were seen flying over. 

 The Solitary Sandpipers were seen in a slough near the farm buildings. 

 On October 23. thousands of Brant were seen flying southward ; they were 

 evidently fleeing from the early cold weather and snow which we had this 

 Fall. Many species of water birds could be seen in this countv if one 

 lived along the Mississippi or Rock River or on Rock River Bottom. I have 

 four new records on my list this fall. A flock of about 50 Lapland Long- 

 spurs were seen in one of our fields on Nov. 4 ; they were also seen and 

 heard Nov. 11. 18. and 19. One Nelson's Sparrow was seen Sept. 23, 

 and one YVhite-crowned Sparrow Oct. 14. Four or five Harris's Sparrows 

 were seen on Oct. 28, while observing three different flocks of sparrows in 

 some timber and brush land ; there was one with the first flock, two or 

 three with the second, and one with the third. Harris's Sparrow is easy 

 to observe, as it is not so restless as other sparrows are. While observing 

 the second flock, I had the pleasure of seeing a Harris's Sparrow, and a Fox 

 Sparrow, sitting about a foot apart. The next day, Oct. 29. it snowed all 

 day from the northwest. The Golden-winged Warbler is a regular visitor 

 here in the fall, but I have never seen any in the spring. It is remarkable 

 that I have never seen any of the blue colored warblers, neither during the 

 spring or fall migrations. On October 25. 1914, I saw a small bird in the 

 brush, which was entirely blue on the back, but when I tried to observe 

 it with my field glass, it had disappeared. It probably was a Black- 

 throated Blue Warbler. J. J. Schaefer.

Check List of Illinois Birds 



The following check list of birds found in Illinois is a very careful 

 revision of the one printed in the Spring 1917 Bulletin. For this the 

 members of the Illinois Audubon Society and all who may have 

 occasion to use this check list are greatly indebted to Mr. Benjamin T. 

 Gault of Glen Ellyn. It has been his somewhat trying task to sift out 

 fully verified records from the hazy or uncertain ones, and to deal with 

 not yet clearly determined matters relating to the variation between north- 

 ern and southern representatives of certain species of birds which make 

 the work of editing a check list rather perplexing. All this and the pro- 

 saic but important work of correcting nomenclature and errors of spelling 

 have doubtless made Mr. Gault's task a heavy one, but it surely has been 

 worth while. The list as now published is authoritative for Illinois as
