Meadowlark. This information would be helyoful in evaluating future ob- 
servations. 
In general, the above charts follow expected patterns — the oriole seen 
most often in American elm, the meadowlarks in grassy fields, Red-winged 
Blackbird on cat-tail, and the grackle on artificial perching sites. If the 
reader is surprised by the variety of perching sites for the Red-winged 
Blackbird, it must be remembered that quite often these represent trees, 
shrubs, and other sites adjacent to cat-tail marshes; and that when con- 
gregating for migration, the birds will often be found away from marshy 
habitats. Following is the semi-monthly distribution of the preceding 
figures:

One is impressed with the preponderance of records in the spring for 
each species. This is undoubtedly due to a greater secretiveness later on in 
the season. All are early spring arrivals, with the exception of the Balti- 
more Oriole. Also, it is this species which departs earlier than the others 
of the group. The members of this family are noted for using artificial 
perching sites. The table below gives each species and the percentage of 
instances it is found perching on selected artificial perching sites:

THE PREVIOUS ISSUE of the Audubon Bulletin (No. 113, March, 1960) 
was distributed so widely to contributors of articles and Census Re- 
ports that we have almost none for our I. A. S. files at the Museum. 
If you have one or more extra copies of this issue which you will not 
need, please mail them to The Illinois Audubon Society, c/o Dr. R. M.
