American Martens in Northern New England

pine marten2 by Laurie Stokes

American Martens (formerly Pine Martens) are making a comeback in northern New England. On New Hampshire’s Threatened Species List, and on Vermont’s Endangered Species List, American Martens are rebounding from the effects of habitat loss and trapping in the early 1900’s, but are still considered rare. This medium-sized member of the weasel family is slightly larger than a Mink and smaller than a Fisher, and often has a light orange bib, or throat/chest patch. Lighter fur usually is found on their head and along the edges of their ears. In addition to a pair of scent glands, which all weasels have, American Martens have a glandular area on their lower abdomen that exudes a musky-smelling, oily secretion used for scent marking.

American Martens spend a lot of time in trees. Their semi-retractable claws help them climb and hang onto branches. In addition, their hind limbs can be rotated at the ankle (like Gray Squirrels) to allow them to descend a tree very quickly, and their long, bushy tail helps them balance.

Because they store very little fat, martens must hunt every day. In the winter they are active for about four hours a day (14 hours/day in the summer), and during this time consume an average of three voles or the equivalent amount of chipmunks, birds or other small rodents. A sighting of an American Marten is a highly-prized experience. (Thanks to Laurie Stokes, whose photo of a Pine Marten was taken in the White Mountains of New Hampshire.)

Red Fox Kits Romping

5-14-15  red fox kits IMG_7313After spending their first month or so underground in their den, red fox kits emerge and discover the great outdoors. This is the most carefree time of their lives – days are spent playing tag, “king of the mountain,” and “hide and seek.” Engaging in mock fights, pouncing on each other as well as on insects (learning how to capture their own food) and tumbling in the dirt are the norm. Food is delivered to them, coats are groomed and life is good.

Coyotes Mating

1-30-15 coyote2  143Coyotes mate in January and February, but pre-mating behavior started two to three months ago. During this period scent marking increases, as does howling, and males wander far and wide. Female coyotes come into heat only once a year. When this happens, and two coyotes pair up, they may howl in a duet before mating. If there is an ample food supply, most females will breed and between 60% and 90% of adult females will produce a litter. The size of the litter fluctuates with the size of the rodent population; lots of rodents means larger litters. The same pair of coyotes may mate from year to year, but not necessarily for life.

Coyote Shelter

2-24-14 coyote shelter 078Like many carnivores, coyotes do not have permanent homes, other than the maternal dens in which their young are raised. After being active at dawn and dusk (as well as occasionally during the day and night), they are apt to rest, curling up in beds they make in the snow right out in the open. However, they will take advantage of a sheltered spot, such as this hollow stump, if it presents itself. Tracks leading into and out of this stump, in addition to many hairs on the ground inside it, left no question as to what canine had sought shelter here from the cold, winter wind.

Mink Meanderings

2-5-14 mink with tail dragging2 IMG_2152As these wet footprints and tail drag marks indicate, mink are excellent swimmers, and spend a great deal of time in all seasons foraging in and along streams and ponds. As a rule, all weasels can often be found close to water, as they drink often, though relatively little at a time. But mink do far more than drink water – they find much of their prey, including crayfish, frogs and fish, in it and are very well equipped to capture them. Mink can swim underwater to a depth of 18 feet and they can swim as far as 100 yards. Look for their tracks going in and out of openings in the ice that covers much of a stream’s surface this time of year.

Coyote Winter Diet

Coyotes are opportunistic carnivores – whatever is available and relatively easy to find and/or catch, coyotes will eat. In spring, summer and fall, insects, small rodents and fruit make up most of their diet. In winter, when insects aren’t around and rodents are hidden by snow, coyotes are more dependent upon carrion, particularly white-tailed deer. Coyotes are often blamed for preying heavily on deer, and their scat often does contain deer hair, but studies have shown that most (92% in one study) of the deer consumed by coyotes are scavenged after being killed by vehicles or having died as a result of other injuries. A large percentage of the deer that are killed by coyotes have severe pre-existing injuries and would likely have died from them had they not been preyed upon by coyotes. (The pictured coyote scat consists largely of rotting apples, with a sprinkling of deer hair.)

Fisher Sign

1-22-14 fisher bed and scat 074You can spend days following the tracks of a fisher – this tireless member of the weasel family travels up to ten miles a day during the winter, foraging for food and stopping to bed down periodically. One of the more common signs of fisher, other than tracks, is their resting spots. Fishers are active day and night, but even they have to stop now and then to rest, often at the base of a tree. More often than not they defecate before departing. If you look closely you’ll see the fisher’s scat – guide books often state that the scat of fishers is dark and twisted. While this is sometimes so, their scat can also be somewhat mustard-color and not be at all twisted, as in this photograph.
