MUSKRATS MATING!

Walking along the edge of the pond I heard a new-to-my-ears sound, an odd sort of mewing, repeated over and over again. What could that be? I snuck along as quiet as could be following the sound. To my amazement, it was a pair of Muskrats cavorting in the reeds, and they were courting and mating!!! You can just barely make out two together in the photo with the dense reeds, too dense to get a good photo, but not too dense to see what they were up to.

A female Muskrat is ready to breed at only one year of age. The breeding season lasts from March through August. A pair will mate while partially submerged, or on water-logged debris above the surface (where our little pair was mating). She may have 2-3 litters per year, with an average of 6 to 8 kits per litter.

Lest folks worry the pond will become overrun with Muskrats, they are a relatively short-lived mammal and have many, many predators including Snapping Turtles, large fish, Eastern Coyotes, Red and Gray Foxes, Weasels, River Otters, Bobcats, Great Horned Owls, and Northern Harriers. But their chief enemy are Minks and Raccoons.

For our reader’s general information, Muskrats are easy to distinguish from Beavers. They are about a tenth the size; Muskrats weigh 1 to 4 pounds whereas Beavers weighs 30 pounds or more. The muskrat’s tail is not large large and flat, but slender and elongated.

The Three Muskrateers

three-muskrat-family-massachusetts-copyright-kim-smithMore muskrat love! Did you know Muskrats eat phragmites?!! They gnaw off the emerging and exposed shoots at the base and then eat the green stems. Very cool. Other fun facts: Muskrats can hold their breath underwater for up to fifteen minutes. They can also chew underwater. Unlike beavers, whose tails are flattened horizontally, a muskrats tail is laterally flattened (in other words vertically). The tail functions like a rudder to help the Muskrat maneuver through water. Muskrats can swim forward and backward.three-muskrat-family-massachusetts-2-copyright-kim-smith

Hermine’s Gifts

Tropical storm Hermine’s rain has breathed new life into Cape Ann’s drought depleted freshwater ponds and brackish marshes. Perhaps it was her winds that delivered a surprise visit from the Yellow-crowned Night Heron, a rarity for Massachusetts as we are at the tippy northern end of their breeding range. Towering waves accompanied by a tumbling undertow tossed from the deep sea gifts of nutrient rich seaweeds, mollusks, and tiny crustaceans, providing a feast for our feathered friends. See all that she brought!
