attributed to variations in the time of flights. Depending upon the occurrence 
of cold fronts and other adverse weather conditions, the greatest movement 
of passerines in fall migration in central Illinois takes place generally 
during the third week in September. 
In the case of both kills, the Tennessee Warbler, Ovenbird, and Red- 
eyed Vireo were among the five species suffering the greatest mortality. 
It was interesting to note that fifteen Bobolinks were picked up after each 
kill; presently this bird is considered rare in central Illinois during migra- 
tion. Most of these birds may go directly through and only during some 
Gisaster such as this would their presence be detected. Species recorded 
for the Sept., 1963, flight but absent in the Sept., 1958, counts include the 
Mourning Dove, Yellow-throated Vireo, Wilson’s Warbler, and Grasshopper 
Sparrow. All are common migrants but, like many of the species of which 
only one or a few specimens were recovered, their occurrence in such kills 
is probably in direct proportion to differences in time and location of local 
migration routes. Records of bird mortality at the WICS-TV tower over a 
period of years will establish more clearly the abundance and percentage 
of fall migrants in this local central Illinois area.
