and
movements
of
sage
grouse
(Centrocercus
urophasianus)
broods
were
studied
with
the
aid
of
radiotelemetry
in
central
Montana
during
the
summers
of
1968
and
19619.
Five
hundred
and
eleven
locations
were
obtained
on
13
radio-marked
sage
grouse
broods.
In
both
sum-
mers
big
sagebrush
(Artemsa
trixlentrata)
in
scattered
(1-10
percent)
and
common
(10-25
percent)
densities
received
the
greatest
utilization
by
broods.
Sagebrush
heights
at
brood
sites
ranged
mainly
between
6
and
18
inches.
For
the
2
years
combined,
sagebrush
canopy
coverage
averaged
14
percent
for
June,
12
percent
for
July,
10
percent
for
August,
and
21
percent
for
September.
Broods
utilized
sagebrush-grassland
benches
early
in
the
summer
(June
and
July)
and
shifted
to
greasewood
(Sarcobatus
vermicalatus)
bottoms
and/or
alfalfa
(Medicago
sativa)
fields
as
the
forbs
on
the
higher
elevations
became
desiccated.
Broods
remained
in
these
bottom
types
until
late
August
and
early
September
and
then
shifted
back
into
sagebrush.
Sizes
of
areas
used
by
broods
averaged
213
acres
in
sagebrush
in
early
summer
(June
and
July),
144
acres
in
alfalfa
fields
(July
and
August),
91
acres
in
greasewood
bottoms
(July
and
August),
and
128
acres
in
sagebrush
in
late
summer
(August
and
September).

Two

Winter

A
4-square-mile

hens
were

during

springs
of
1969,
1970,
1971,
and
1972.
Thirty-one
sage
grouse
hens
were
radio-equipped
resulting
in
22
nests
being
located.
Nineteen
additional
nests
were
located
dur-
ing
nest

and
work
incidental
to
telemetry.
Adults
laid
larger
clutches
than
yearling
hens
and
also
were
more
successful
in
bringing
off
a
brood.
Sixty-eight
percent
of
the
22
nests
of
radio-equipped
hens
occurred
within
1.5
miles
(2.5
km)
of
the
strutting
ground
where
the
hens
were
captured.
Sagebrush
(Artemisia
tridentata)
formed
the
nesting
cover
over
all
of
the
nests
located.
Successful
nests
were
located
in
sagebrush
stands
with
a
higher
average
canopy
coverage
than
those
of
unsuccessful
nests,
and
had
significantly
greater
sagebrush
cover
within
24
inches
(60
cm)
of
nest
and
within
a
100-square
foot
(9-m2)
plot
around
nest.
Consideration
of
the
ecological
requirements
of
animals
affected
by
pub-
licly
funded
programs
is
important.
This
is
especially
true
of
sage
grouse
since
extensive
areas
of
sage-
brush
have
already
been
eliminated
or
modified
by
such
programs
with
little
apparent
regard

the
welfare
of
