Bird Watchers Wanted 
Dr. ALBERT WOLFSON, professor at Northwestern University, Evanston, 
Illinois, would like to enlist the help of the members of the Illinois 
Audubon Society in making a count of white-throated sparrows and myrtle 
warblers during May. He is making this study in cooperation with the 
Wisconsin Society for Ornithology, which is making a migration census 
of these two species. 
Birders scattered over the state of Wisconsin are pledged to make 
daily observations of this count in their vicinity in an effort to determine 
the relationship between weather, winds and time in the appearance of 
the birds, and also whether they appear suddenly throughout the state, 
or move in a steady fiow from south to north. People who have kept 
records for a period of years, especially of trapped or banded birds, are 
particularly sought by Dr. Wolfson. He wants information about the 
fall migration also, and observations at this time are meager as far as 
reported results are concerned. Even sight records at intervals will be 
welcome. 
Local bird clubs throughout the state of Illinois are urged to partici- 
pate. Records of the Cahokia Nature League, for instance, or some other 
group in the south, would make interesting reading in comparison with 
the reports from Superior, Wisconsin. We hope to publish the eventual 
results of these surveys in the Passenger Pigeon (‘Wisconsin) as well as 
in the Illinois Audubon Bulletin. Dr. Wolfson is collecting the reports 
from this area and forwarding them to the Wisconsin group. Clubs or 
individuals wishing to participate are requested to write to Dr. Albert 
Wolfson, 2016 Sheridan Road, Evanston, Illinois. 
Book Reviews 
“Birds of Montezuma and Tuzigoot,”’ by Henry H. Collins Jr., illustra- 
tions by Roger Tory Peterson. Published by Southwestern Monuments 
Association, Box 2011 J, Santa Fe, N.M. Price 25 cents. 
This 16-page booklet, including cover, is the first of a series planned 
by Mr. Collins for various national parks and monuments. It is directed 
toward the average park visitor with a potential but not yet developed 
interest in nature. The booklet is an introduction to the birds most likely 
to be seen in a particular park, each species being represented with either 
a color or black and white sketch by Peterson, a bit of history and general 
information about the bird, and field marks. Also included is a quiz 
section based on the text, a description of the park or monument area 
with tips on where particular birds may be found, and a check list of 
all birds reported in the area. 
Mr. Collins, whose address is 136 Parkview Ave., Bronxville, N.Y., has 
done an excellent job on this project, covering two national monuments 
in Arizona, and it is to be hoped he will be able to do the same for many 
more areas. The seven postcard size Peterson paintings alone should more 
than recompense any park visitor for the nominal price asked.
