30 THE AUDUBON BUD Bie 
launched next spring by Illinois Natural History Survey wildlife biologists. 
They plan to trace a group of night-flying thrushes by means of tiny 
radio transmitters attached to their backs — the first such large scale 
piece of research of this kind by INHS. The main objective is to determine 
what cues the thrushes use to steer by.

LETTER TO THE EDITOR / Writes Ralph M. Eiseman, faculty member 
of Highland Park High School: “How many people have heard about the 
Willets seen last week in Waukegan or the Little Blue Heron seen last 
month at Illinois Beach State Park — etc.? I have, and it’s frustrating: 
I propose, therefore, that some local bird club assume basic responsibility 
of setting up a rare bird alert, patterned somewhat after the Massachusetts 
system ... through a telephone recording service. It would be invaluable 
to local birders as well as out-of-town visitors.”

Prairie Chicken Foundation Buys 5th Sanctuary 
A sixty-acre tract of high prairie soil, an extension of the lateral moraine— 
predominate range of the native prairie grouse in southeastern Illinois — 
has been purchased as Sanctuary No. 5 by the Prairie Chicken Foundation 
of Illinois. This 60 acres joins Sanctuary 3 — the Donnelley 60 acres on the 
east. The addition will be sowed to permanent grassland this winter, 
adding essential nesting and brood rearing cover. This will make a total 
297 acres owned or managed by the P.C.F.I. in its effort to preserve this 
magnificent species in IIlinois. 
This added obligation necessitates raising of $10,000 revenue per year 
to meet payments. Sponsoring organizations and loyal contributors are 
expected to make an extra financial effort in 1968 to meet indebtedness. 
Those interested in assisting in preservation of this species are en- 
couraged to mail contributions to Elmer Neulieb, Treasurer, 309 South 
Cakwood, Geneseo, Illinois. All contributions are tax exempt.
