wildlife management are identified. 
Research should be directed toward 
various aspects of hunter behavior, 
nonconsumptive uses of wildlife, wild- 
life economics, and political-legal 
issues. As nonconsumptive use of 
wildlife increases, managers are chal- 
lenged to both gain support from and 
supply satisfaction to appreciative 
users.

Results are reported of studies of 
peregrine falcons in the lower Hudson 
River Valley, New York, from 1930 to 
1960. By 1961 the falcon population 
was extirpated following several years 
of persecution by humans. Disturbance 
resulted in abandonment of clutches 
and persistent renesting.

Among factors responsible for the 
elimination of peregrine falcons from 
the Hudson River Valley, New York, was 
extreme persecution by humans. Shoot- 
ing and trapping of adults, robbing of 
young and disruption of breeding 
adults by falconers, and the construc- 
tion of a highway and recreation fa- 
cilities in the valley all contributed 
to the extirpation.

The decline in the numbers of breeding 
peregrine falcons in Switzerland and 
possible reasons for the decline are 
discussed. Human disturbances includ- 
ing camping and rock climbing have 
caused some losses. Some eyries have 
been abandoned due to noise and other 
human disturbances.

Grizzly bear attacks on humans in Na- 
tional Parks of North America are ex- 
amined. Hiking, camping, or provoca- 
tion of the bear preceded attacks in 
98% of cases. Opinion surveys indi- 
cated that the public favored more ef- 
fective management of people’ and 
bears, rather than elimination of 
bears, as a solution to man-bear prob- 
lems.

Data are examined relating to grizzly 
bear-human interactions. Circum- 
stances related to attacks and man's 
values and attitudes relating to griz-~ 
zly bears are discussed. The author 
contends that human-bear coexistence 
is possible, and is especially valu- 
able in Glacier and Yellowstone Na- 
tional Parks.
