    Black bear

    Capable of killing people, though the agency says this is extremely rare. “Yes. Black bears are capable of killing people, but it is an extremely rare occurrence. The last time someone was killed by a black bear in New Hampshire was 1784.” New Hampshire Fish and Game Department

  • Raccoons, skunks, bats and foxes

    Account for most reported rabies cases in New Hampshire, per NH Fish and Game. “…as raccoons, skunks, bats and foxes account for most of the reported rabies cases in New Hampshire.” New Hampshire Fish and Game Department

What the sources say

Habitat: Mixed deciduous and coniferous forests with a variety of horizontal and vertical structure. Conifer cover is important during winter and course woody debris on the ground provides denning and nesting sites and refuge from predators. Typically found in spruce-fir forests above 2,700 feet in elevation. (New Hampshire Fish and Game Department)

Where in New Hampshire
The Little Brown Bat is found from Labrador west to central Alaska and south to the Appalachians in Georgia and Arkansas … New Hampshire Fish and Game Department
Conservation
NH endangered; Species of Greatest Conservation Need
What the sources say

Range: The Little Brown Bat is found from Labrador west to central Alaska and south to the Appalachians in Georgia and Arkansas. Located in most states except Florida, Texas, and southern California. The little brown bat was found abundantly throughout New Hampshire until about 2010, but the entire population is now at great risk from White-nose Syndrome.

Habitat: Little brown bats feed primarily over wetlands and other still water where insects are abundant. They use rivers, streams, and trails as travel corridors to navigate across the landscape. Bats will occasionally swoop down close to mammals to indulge on the insects that swarm around them. They can follow the same flight pattern each night as they search for food. They will prefer summer roosts close to water. (New Hampshire Fish and Game Department)

Mammals people confuse

Bobcat or Canada lynx?

Bobcat Not stated

Canada lynx

Canada lynx Not stated

A lynx has longer ear tufts and large, fur-covered feet (3.5 to 4.5 inches wide). A bobcat's feet are small and hairless (up to 2.5 inches). A lynx's tail has a black tip and no white underneath; a bobcat's tail is white underneath. Do not use the tail tip alone, because agencies describe the bobcat's tip differently (New Mexico white, Arizona black).

Coyote or Gray wolf?

Gray wolf
Photo: Robbie Hannawacker · CC0 1.0 · iNaturalist

Gray wolf Not stated

NY DEC: gray wolves are much larger (females typically 50-100 lb, males 70-145 lb, 5-6 ft nose to tail, 27-33 in at the shoulder); eastern coyotes rarely exceed 50 lb and generally stand under 2 ft at the shoulder. Wolves have small rounded ears and a short blocky snout; coyotes have larger, more pointed ears (can look rounded in winter coat) and a long, narrow, pointed snout. Coyote tracks are typically 3 x 2 in, wolf tracks about 5 x 4 in. NY DEC says most wolf reports in New York were coyotes, dogs or wolf-dog hybrids.
