Mammals taken Along the Alaska Highway Part 7

Grizzly

_Specimens examined._--Total 5, as follows: _Yukon Territory_: E side Aishihik River, 17 mi. N Canyon, 1; Unahini River, 5 mi. N and 1 mi. E Dalton Post, 1; Unahini River, 3 mi. N and 1 mi. E Dalton Post, 2.

_British Columbia_: Buckinghorse River, 94 mi. S Fort Nelson, 1.

_Remarks._--Of three specimens obtained at the Unahini River, two males resemble each other closely, while the third, an old adult represented by an uns.e.xed skull with broken cranium, is markedly different, the skull being noticeably shorter with shorter rostrum and lower jaw and other distinctive features. It closely resembles the skull of an adult male taken at the Aishihik River. Furthermore, the first two animals show close relationships with an uns.e.xed skull which Alcorn obtained at the Buckinghorse River in British Columbia.

Two males taken at the Unahini River in the Yukon Territory have the following external measurements: Total length, 1933, 1812; tail, 150, 96; hind foot, 262, 260; ear from notch, 129, 131. Other specimens, skulls only, obtained from native hunters, are partly broken. Alcorn writes that the local hunters always shoot a grizzly in the head to be certain that it is dead.

_Specimen examined._--One (broken and uns.e.xed skull) from _Yukon Territory_: Champagne, N side Dezadeash River.

_Remarks._--While studying moose at Medicine Lake, near Circle Hot Springs, Alaska, on August 9, 1947, Alcorn observed some mink concerning which he records the following: "After waiting about an hour a large mink was seen traveling northward on land at the edge of the lake. It continued and went out of sight. I waited about two minutes and then started a series of loud squeaks. To our surprise we soon saw what we judged was the same mink. In company with this mink were five others.... These mink were much interested in the squeaking noise and some came within 10 feet of me. They stayed on land most of the time but some of them made short swims a few feet out into the lake. One had a white chin, another had a white spot on its chest.

This group may have been an adult female with her young."
