WILDFLOWERS OF EASTERN 
NORTH AMERICA 
By John Klimas and 
James Cunningham 
276p. 304 color photographs 
and 
WILDFLOWERS OF WESTERN 
NORTH AMERICA 
By Robert and Margaret Ore 
276 p. 291 color photographs — both 
volumes from Alfred A. Knopf, 
New York, 1974, $17.95 each 
These two books provide a cov- 
erage of nearly 800 representative 
flowers of the U.S. The color photo- 
graphs are excellent and the repro- 
duction is fine. Both volumes are 
comparable in photographic quality 
to the series by Rickert on the 
more limited geographic regions. 
In addition to the photographs the 
text describes the plants and is 
organized by color rather than tax- 
onomy to make identifications 
easier for the amateur. A section 
on edible and medicinal plants is 
included as well as a glossary of 
terms, common and scientific in- 
dexes. The dividing line between 
the volumes is the Mississippi 
River, making it desirable to have 
both for use in Illinois.

GARDENING WITH WILDLIFE 
By Russell Bourne, Ed. National 
Wildlife Federation, 
Washington, D.C., 1974, 
19lp., many line drawings and 
color plates, $12.95 
Since most of the land in this 
country is owned by private in- 
dividuals the National Wildlife 
Federation reasons that more wild- 
life habitat can be created by peo- 
ple developing their own property 
than by any other means. In a 
beautifully produced and laid out 
book eight authors show the reader 
how to turn his backyard into a 
wildlife refuge. It includes plant- 
ing maps, feeding charts, a month 
by month gardener’s. calender, 
landscaping to provide natural 
homes and food, designing brush 
shelters, building pools and water- 
falls for pond life and construct- 
ing bird feeders, baths and houses. 
It accomplishes its purpose while 
also providing a selection of fine 
nature photographs which illus- 
trate the suggestions made in the 
text.

AUTUMN HAWK FLIGHTS — 
THE MIGRATION OF EASTERN 
NORTH AMERICA 
By Donald S. Heinzelman 
Ruigers University Press, 
New Brunswick, N.J., 1975, 
398p., 88 black-and-white photo- 
graphs, 48 maps, 60 tables, 
40 charts, drawings and graphs, 
$30.00 
For those interested in recording 
hawk migration in Illinois, this 
book is a must. The first part is 
devoted to techniques and proce- 
dures used in studying and record- 
ing migrations and to pictorial and 
descriptive clues used for accurate 
identfication of the hawks as they 
fly past at eye-level or high over- 
head. The second part lists and de- 
scribes most hawk lookouts from 
Canada through Central America 
with most emphasis on Middle At- 
lantic lookouts which includes 
Hawk Mountain. There was no 
mention of the hawk flights which 
pass through Illinois. The rest of 
the text deals with flight, weather 
patterns, migration routes and the 
various conditions allowing or caus- 
ing the hawks to migrate the way 
they do. It explains the function 
of thermals and up-drafts and how 
migration can be predicted by ap- 
propriate weather conditions. In 
appendix, numerous tables show 
actual count data, banding results 
and population trends. Although 
somewhat expensive, this is an ex- 
cellent book for observers wanting 
to learn more about hawk migra- 
tions. —Editor
