Demise of the Translocated Wolves

All four translocated wolves were killed by humans (Table 8). The alpha

male (No. 12) was the first victim. He was found from the air in the

same location on July 6 and 10. A ground check on July 11 showed him

already decomposed. He lay about 60 feet (18.3 m) from paved highway US

141 north of Amasa (Fig. 22). The articular processes on the right side

of his fifth and sixth cervical vertebrae were broken and inverted. Part

of the process of the sixth cervical vertebra was lodged in the neural

canal between the fifth and sixth cervical vertebrae and would have

exerted pressure on his spinal cord. His acrylic radio collar was also

cracked on the right side in three places. We concluded that he had been

struck and killed by an automobile. A scat found beneath the remains

contained deer hair, so apparently the animal had been feeding not long

before his death.

highway, and broken bones indicated he had been hit by a vehicle (Photo

Wolf No. 13 was killed next. He had been located south of Sagola in

Dickinson County on July 20, the first time he was found since June 27.

He was still there on July 27, so a ground check was made. It revealed

that the wolf had been dead for perhaps 2 or 3 weeks. His flesh had

decomposed, and only hair, bones and the transmitting collar remained

(Fig. 23). His leg bones and ribs were mostly disarticulated, his skull

was separated from the vertebral column, and his mandible had separated.

A small caliber bullet had passed through the ramus of the left mandible

and had entered the base of the cranium. The hole through the mandible

was 0.26 inch x 0.34 inch (6.6 mm. x 8.6 mm.) and that through the

cranium was 0.34 inch x 1.30 inch (8.6 mm. x 33.0 mm.). Three small lead

fragments were removed from the cranium.

jawbone indicates (Photo by Tom Weise)_]

The remains of Wolf No. 13 were sent to the Michigan Department of

Natural Resources Wildlife Research Center at Rose Lake and examined by

staff pathologists Dr. L. D. Fay and Mr. John Stuht. No fractures or

other signs were found that might indicate that he had been trapped.

However, some of the smaller foot bones were missing and a complete

examination was not possible. Notches were found in both shoulder

blades, and one rib was broken, suggesting that the animal had been shot

twice by a small caliber firearm in addition to the head shot. The hole

in the left scapula indicated a deep penetrating wound. The notch in the

right scapula indicated a bullet traveling more parallel to the body.

Wolf No. 11 was caught the night of September 19, 1974 in a coyote trap

set by a trapper from Channing. The next morning the trapper came upon

the trapped wolf by surprise at a range of 12 feet (3.6 m). She growled

and lunged toward him, and thinking he was in danger, the trapper shot

the wolf in the head. The .22 caliber bullet entered below the right eye

and lodged in the skull. The trapper immediately took the animal to the

Michigan Department of Natural Resources office in Crystal Falls and

reported the incident.

The wolf weighed 56.5 lb. (25.6 kg), 1.5 lb. (0.68 kg) less than when

she was brought to Michigan. Her general condition was good, with some

omental fat, but no subcutaneous fat. She did harbor ten tapeworms

(_Taenia pisiformis_) about 40-50 cm long and a few hookworms

(_Uncinaria stenocephala_), as determined by Mr. John Wenstrom (personal

communication), Biology Department, Northern Michigan University. Both

are common tapeworms of wolves (Mech 1970).

Wolf No. 10 was shot by a deer hunter, probably on the morning of

November 16, the second day of firearms deer season. On November 17 her

signal was heard from near a cabin on the south shore of Van Riper Lake.

The hunters occupying the cabin later said they had removed the collar

from the wolf, which they had found dead on the afternoon of November

16. Before we had learned this, the carcass of Wolf No. 10 was

discovered without the collar by another hunter, about a half mile (0.8

km) south of Van Riper Lake. It had been shot through the right leg,

shattering the radius and ulna, and through the head, the bullet

entering the left frontal bone and exiting below the right eye. In

addition the radio collar had been shattered by a bullet and was

missing, and one ear had been cut off. We identified the wolf from the

tag in the other ear.

The wolf had gained 6 lb. (2.7 kg) since she had been brought to

Michigan, and had heavy internal and subcutaneous fat. She had light

infections of two species of tapeworms (_Echinococcus granulosus_ and

_Taenia pisiformis_), and of one species of hookworm (Uncinaria

stenocephala), as determined by John Wenstrom. _Echinococcus granulosus_

is not uncommon in wolves (Mech 1970). The other two species were

discussed above.
