### Identification Look for a lithe, cigar-shaped silhouette draped in fur so dark it appears nearly obsidian, especially when slicked with water. The American Mink (*Neogale vison*) is a medium-sized mustelid, typically 12–20 inches long. The definitive field mark is a stark white patch on the chin, and occasionally the throat, set against a rich chocolate-brown body. While beginners may mistake them for River Otters, the mink is significantly smaller with a more pointed muzzle and a narrower, less flattened tail. Unlike the Long-tailed Weasel, the mink lacks a pale yellowish underbelly, maintaining its dark, uniform coloration throughout the year.
### Habitat & Range The mink is a creature of the "edge," rarely found far from a shoreline. They occupy nearly all of North America, from the subarctic tundra to the swamps of Florida. You will find them patrolling the rocky margins of trout streams, the tangled reeds of freshwater marshes, and even coastal salt marshes. They require dense cover—think fallen logs, root tangles, and thick riparian brush—to feel secure.
### Behaviour Watching a mink is a lesson in perpetual motion. They move with a characteristic "bounding" gait, arching their backs with every stride. While primarily crepuscular, they are bold and often hunt in broad daylight. They are solitary and fiercely territorial, using scent glands to mark their boundaries with a pungent, skunk-like musk. During the spring breeding season, males become nomadic, traveling miles of shoreline in search of mates.
### Diet The mink is a relentless generalist. It is an "all-terrain" predator, equally comfortable diving for crayfish and trout as it is raiding a muskrat lodge or snatching a marsh wren. They are high-metabolism hunters that kill with a precision bite to the back of the skull, often caching extra prey in their dens during successful hunts.
### Fascinating Fact The mink’s coat is so dense—boasting nearly 29,000 hairs per square inch—that when they dive, air becomes trapped in the underfur. This creates a silvery "bubble" around their body that acts as an underwater dry suit, keeping their skin perfectly dry even in near-freezing currents!
