ALASKA RED FOX (Vulpes kenaiensis)

The red fox of the Kenai Peninsula, Alaska, and the adjacent mainland

is probably the largest of its kind in the world, although those of

Kodiak Island and of the Mackenzie River valley are nearly as large.

Compared with its relatives of the United States, the Kenai fox is

a giant, with heavier, duller-colored coat and a huge tail, more

like that of a wolf than of a fox. The spruce and birch forests of

Alaska and the Mackenzie Valley are apparently peculiarly adapted to

red foxes, as shown by the development there of these animals--good

illustrations of the relative increase in size and vigor of animals in

a specially favorable environment.

As noted in the general account of the red foxes, the occurrence of the

black phase is sporadic, and the relative number of dark individuals

varies greatly in different parts of their range. The region about the

upper Yukon and its tributaries and the Mackenzie River basin are noted

for the number of black foxes produced, apparently a decidedly greater

proportion than in any other similarly large area. The prices for which

these black skins sell in the London market prove them to be of equal

quality with those from any other area.

Like other red foxes, the Alaskan species digs its burrows, with

several entrances, in some dry secluded spot, where both male and

female share in the care of the young. In northern wilds the food

problem differs from that in a settled country. There the surrounding

wild life is the only dependence, and varying hares, lemmings, and

other mice are usually to be had by the possessor of a keen scent

and an active body. In summer many nesting wild-fowl and their young

are easy prey, while heathberries and other northern fruits are also

available.

Winter brings a season of scarcity, when life requires the exercise of

every trained faculty. The snow-white ptarmigan is then a prize to be

gained only by the most skillful stalking, and the white hare is almost

equally difficult to secure. At this season foxes wander many miles

each day, their erratic tracks in the snow telling the tale of their

industrious search for prey in every likely spot. It is in this season

of insistent hunger that many of them fall victims to the wiles of

trappers or to the unscrupulous hunter who scatters poisoned baits.

Fortunately the season for trapping these and other fur-bearers in

Alaska is now limited by law and the use of poisons is forbidden. These

measures will aid in preserving one of the valuable natural assets of

these northern wilds.

=GRAY FOX= (=Urocyon cinereoargenteus= and its relatives)

Gray foxes average about the size of common red foxes, but are longer

and more slender in body, with longer legs and a longer, thinner tail.

They are peculiar to America, where they have a wide range--from New

Hampshire, Wisconsin, and Oregon south through Mexico and Central

America to Colombia. Within this area there are numerous geographic

forms closely alike in color and general appearance, but varying much

in size; the largest of all, larger than the red fox, occupying the New

England States.

Gray foxes inhabit wooded and brush-grown country and are much more

numerous in the arid or semiarid regions of the southwestern United

States and western Mexico than elsewhere. In parts of California they

are far more numerous than red foxes ever become. They do not regularly

dig a den, but occupy a hollow tree or cavity in the rocks, where they

bring forth from three to five young each spring. As with other foxes,

the cubs are born blind and helpless, and are also almost blackish in

color, entirely unlike the adults. The parents, as usual with all

members of the dog family, are devoted to their young and care for them

with the utmost solicitude.
