_Wolf 1053._--This wolf was basically a scavenger who subsisted for

long periods on the remains of old carcasses. She was known to have

visited the remains of at least four deer and three moose, and she

stayed near one moose carcass from February 8 to 20, at least during

the day. Between her date of capture, December 10, and February 28,

1053 traveled about in an area of 31 square miles in the Arrow

Lake-Maniwaki Lake region (fig. 21).

selected lakes are shown._]

Between February 28 and March 6 she suddenly moved 13 miles to the

east-southeast near the Sawbill Trail, and during the next week she

traveled a straight line distance of 24 miles southwest to a point

southeast of the town of Isabella. Her subsequent travels eventually

took her over a much larger area. Before February 28, 1053's average

weekly straight line distance was 2 miles, but after that date it

increased to 11 miles.

_Wolf 1055._--The range of this animal from January 5, when she was

captured, to February 23 covered about 40 square miles near Stony Lake,

Slate Lake, and the Jack Pine Lookout Tower (fig. 22), and her mean

weekly distance was 4 miles. Between February 23 and 24, however, she

traveled 13 miles northeastward, the beginning of a series of long

moves. By March 5, 1055 had reached Crescent Lake, a point 39 miles

east-northeast of her previous area of intensive use. She then

gradually headed back toward the west and south during the next 10 days

and within the next month repeated this pattern. When her signal was

heard last on May 30, 1055 was near Martin Landing in the center of her

range. Her mean net weekly distance after February 23 had increased to

22 miles.

selected lakes are shown._]

_Wolf 1057._--The movements of 1057 cannot be considered normal

because freezing of a front foot prevented her accompanying the pack of

which she was a member. Nevertheless, even data from an abnormal animal

can provide some information. On January 13, 5 days after capture and

release on Red Rock Lake, 1057 was located 4 miles from the capture

point with a pack of 10 other wolves. She was limping and fell behind

when they moved. Five days later she was again seen with the pack 12

miles away between Knife Lake and Kekekabic Lake. She then remained in

about 14 square miles of that general area through April 17 (fig. 23).

[Illustration: _Figure 23.--Locations and range of wolf 1057. Only

selected lakes are shown._]

Suddenly on April 24, 1057 was found in Ontario some 31 miles northeast

of her location of the previous week. That was the last time we heard

her signal even though on May 2 we scanned an area with a radius of 35

miles from her last known location and listened for her signal during

every subsequent flight.

_Wolf 1059._--This animal was a member of a pack of three to five

wolves (see next section). The movements of the group varied little and

were concentrated in the August Lake, Omaday Lake, and Keeley Creek

area in about 43 square miles (fig. 24). Contrary to animals 1051,

1053, and 1055, this pack did not suddenly begin a series of longer

weekly movements in late February. Both before and after February 28,

the average weekly straight line movement of the pack was just less

than 3 miles.

[Illustration: _Figure 24.--Location and range of wolf 1059 and pack.

Only selected lakes are shown._]

Probably these animals did begin traveling more in late February, for

their net daily distances did increase at that time along with those of

the other wolves (table 4). However, the increased travel took place

within the restricted area of the pack's usual range rather than in new

areas as occurred with the other wolves.

Because 1059 was later found to have bred and carried five fetuses, her

movements during whelping season (late April and early May) are of

interest. Her locations on both April 24 and May 2 were within 250

yards of each other, which might indicate that she was denning. On May

9, however, she was 2.5 miles east of these locations, on the 17th and

21st was 2 miles west of them, and on the 30th was 3 miles north of

them.

In early January 1970, Wolf 1059 was killed by a trapper in the

southeast corner of her pack's 1969 range.

_Summer locations._--Signals from only 1053 and 1059 were heard during

summer, and then tracking attempts were made only on June 28, July 29,

and August 29. Locations for 1053 on those occasions were near Kelly

Landing and Isabella Lake, within her previous range. Wolf 1059 was

found each time within 2 miles outside of the southwest corner of the

pack's winter and spring range.
