regulations for grouse without being labeled as 
AHM. Trial and error comes to mind. 
The chapter by Oyler-McCance ct al. on global 
climate change using White-tailed Ptarmigan (L 
leucum) as a vehicle is novel and explores new 
approaches. The data are presently unclear and it 
is not known which of several variables arc 
inrolved with the apparent changes over a 70+ 
;.earpenod. It is of interest that population size in 
ihe area studied over this period has not changed 
drastically. 
I was unable to attend the 11 th International 
Grouse Symposium and now wonder what I missed 
in the presentations (papers) that did not make it 
into Studies in Avian Biology Number 39. Research 
on species of grouse has contributed to science on 
many fronts. As this volume demonstrates, grouse 
remain ideal research subjects to explore a wide 
variety of topics important to ornithologists. 1 
recommend this Volume to everyone interested in 
grouse or emerging techniques for examining 
processes that affect population biology. It is 
remarkably well organized and free of obvious 
errors.—CLA1T E. BRAUN. Grouse Inc., 5572
