An extensive search was made for 1051's signals on May 2 in an area of at least 50 miles radius from his last known location, but it was unsuccessful. On each subsequent tracking flight, the wolf's frequency was also monitored with no success. Possible explanations for the loss of the signal from this wolf include the following: (1) premature expiration of the transmitter, (2) capture of the wolf and breakage of the transmitter, (3) loss of the exposed antenna and consequent reduction of range, and (4) travel of the wolf out of range of the tracking aircraft. During 1051's travels a number of interesting events took place: Nov. 27, 1968--Captured and radiotagged Dec. 4, 1968--Crossed road in front of tracking truck Dec. 8, 1968--Moved to Area B Dec. 9, 1968--Surprised on the ground at distance of 35 feet Dec. 18, 1968--Chased by loggers with axes Dec. 25, 1968--Almost shot by trapper who saw collar and withheld fire Jan. 5, 1969--Returned to Area A Jan. 13, 1969--"Bumped" twice on logging road by loggers in auto but no apparent injury Feb. 4, 1969--Moved to Area C Feb. 26, 1969--Began long-range southwest movement considered to be dispersal Mar. 14, 1969--Seen feeding on old carcass within 200 yards of houses, dogs, and a man walking Mar. 27, 1969--Chased two deer across 4-lane State highway 53 Apr. 3, 1969--Found with another wolf at point farthest south in his range Apr. 24, 1969--Last contact with this animal; was seen traveling NW _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). [Illustration: _Figure 21.--Locations and range of wolf 1053. Only 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.
