This paper summarizes present manage- 
ment and control programs, known mor- 
tality data, and biological informa- 
tion on grizzly populations in Montana 
and the Yellowstone region. Manage- 
ment in Montana has been based on reg- 
ulated hunting, studies of garbage 
dump closure, and man-caused bear mor- 
tality studies. Problems associated 
with various management practices are 
discussed,

This popular article recounts recent 
problems with grizzly bears and visi- 
tors in National Parks, and summarizes 
research activities of Dick Russell in 
Jasper National Park and Steve Herrero 
in Banff National Park. Conditions 
under which bear attacks on humans are 
likely to occur are listed, and man- 
agement activities carried out to date 
and necessary in the future are de- 
scribed.

Data are presented concerning behavior 
and productivity of bald eagles in re- 
sponse to climbing to nests in Ontar- 
io. No evidence was found of changes 
in bald eagle productivity resulting 
from single climbs to nests when young 
were from 2 to 1l weeks old.

A report of the committee on environ- 
mental quality is presented, including 
consideration of snowmobile effects on 
wildlife and wildlife habitat. A de- 
ficiency in snowmobile recreation 
planning has been a lack of concern 
for environmental impact, including 
harassment of wildlife and intrusion 
into big game winter ranges. The au- 
thor recommends the protection of 
critical wildlife habitat and the es- 
tablishment of laws regarding harass- 
ment of wildlife.

Nesting bald eagles 
Auk 93:842-843. 
While studying bald eagles on the Ko- 
diak National Wildlife Refuge, Alaska, 
a researcher was attacked by a pair of 
eagles. While climbing a tree to 
reach an eagle nest, the researcher 
was struck with some force on the back 
by one of the eagles; both birds re- 
peatedly flew very close but did not 
strike again.
