Autumn Bird Watchers Wanted — VI 
By JAMES H. ZIMMERMAN 
THE COOPERATIVE MIGRATION StupY for the fall of 1957 hopes to have an 
even greater number of observers in Illinois in order to complete its investi- 
gations of southward flight patterns in the Middle West. Our appeals for 
help have resulted in fine cooperation from a large number of Illinois bird 
watchers, but we still do not have adequate coverage in the central and 
southern counties. There can never be too many reports. 
A valuable report only has to include the arrival and departure dates 
of a handful of the species listed below. Daily observations of the same 
species in the same area provide the most useful data. Random “birding”’ 
notes covering widely scattered areas at irregular intervals are not espe- 
cially helpful. Counts or estimates of the numbers of birds seen, and the 
dates on which these numbers reached a peak, give us some assistance. 
For this year, the fall list includes noctural and diurnal migrants, early 
and late travelers, solitary and flocking species — each one included for a 
specific purpose. In some cases, we are attempting to correlate bird move- 
ments with weather conditions. In other cases, we are gathering data for 
technicians studying a particular species. These are the birds on which 
reports are wanted: 
Canada Goose Catbird Rose-br. Grosbeak 
Mallard Duck Hermit Thrush Evening Grosbeak 
Broad-winged Hawk Golden-cr. Kinglet Slate-col. Junco 
Wilson’s Snipe Myrtle Warbler Am. Tree Sparrow 
Mourning Dove Red-winged Blackbird White-cr. Sparrow 
Common Nighthawk Baltimore Oriole White-thr. Sparrow 
Chimney Swift Purple Grackle Fox Sparrow 
Crested Flycatcher
