DICTIONARY OF BUTTERFLIES 
AND MOTHS IN COLOR 
By Allan Watson and 
Paul E.S. Whalley 
McGraw Hill, New York, 1975 
295 pp. $29.95 
Scientists, nature enthusiasts, 
amateur collectors and professional 
lepidopterists alike will welcome 
the unique and handsomely illus- 
trated Dictionary. 
While many books treat the sub- 
ject of butterflies or moths sep- 
arately, this is the first and only 
book to combine both subjects in 
a single volume, giving complete 
data on all the families of butter- 
flies and moths throughout the 
world in an easily referred to A-Z 
dictionary format. Some 2,000 en- 
tries provide such information as 
distribution, habitats, food plants, 
sizes, and any strange relationships 
that occur (e.g., ant-raised cater- 
pillars, and yuccas that are fertil- 
ized by moths). In addition, the 
book contains 144 pages of full 
color plates illustrating over 1,000 
life-sized species alive and in their 
natural habitats, as well as those in 
set specimen pieces. 
Both authors are associates in 
the Department of Lepidoptera at 
the British Museum (Natural His- 
tory), which has the largest col- 
lection of butterflies and moths in 
the world and is also the foremost 
center for the study of lepidopter- 
ology. The introduction to the book 
was written by W. Donald Duck- 
worth, Curator of Lepidoptera at 
the National Museum of Natural 
History, Smithsonian Institution, 
Which has the largest collection of 
butterflies and moths in~ North 
America. —vVictor de Keyserlirig 
TO SAVE A BIRD IN PERIL 
By David R. Zimmerman 
Coward, McCann and Geoghegan, 
Inc., New York, 1975, 286pp., $9.95 
Endangered species is a familiar 
topic among today’s conservation- 
ists and many persons travel great 
distances to see such species before 
they become extinct. How many of 
these same people are willing to 
donate time and energy to preserve 
these species? 
Mr. Zimmerman, in this new book, 
relates the personal dedication of a 
few men and women to the sur- 
vival of such species as the Pere- 
grine Falcon, Osprey, Cahow, 
Whooping Crane, Nene Goose, Kirt- 
land’s Warbler and a few foreign 
species. Included are authentic de- 
tails about recent techniques de- 
veloped to save particular species 
and the progress realized as a result 
of experiment and research. The 
author points out that imprinting 
(“process through which a young 
bird developes its species’ specific 
behavioral traits after watching its 
parents and surroundings during a 
brief, highly indelible period just 
after hatching.) may be used to 
change a species requirements and 
thereby increase its potential sur- 
vival. Such behavioral changes 
may include the modification of 
nesting sites to reduce predation, 
the adaption to new food sources, 
the acceptance of new habitats, etc. 
Mr. Zimmerman emphasizes that 
much more needs to be done for 
endangered species and that all 
conservationists should actively 
participate in the conservation of 
these species rather than passively 
accept their declines. This book is 
highly recommended to people in- 
terested in endangered species pro- 
grams and _ progress’ achieved 
through 1975. —Editor
