OTTER KIT STEALS FROG FROM OTTER MOM?

Mother Otters burrow near to, and within, North American Beaver lodges, to give birth and to raise their young. The den will often have many entrances and exits. The mother raises her young alone. At about five weeks old the newborns will begin playing. At two months, the kits (also called pups) coat has grown in and she introduces them to water. At nine weeks they begin to eat solid food and are weaned by twelve weeks.

The family bond is beautiful to watch and the young River Otters are utterly adorable in their playfulness. Just some of the familial behaviors that have been so wonderful to observe–otters grooming each other, snuggling under Mom (and playfully biting her tail), siblings wrestling each other, and all taking a morning nap together.

One of the most interesting moments was observing what happened one morning after the mother caught a frog. At first look it appeared as though the kit was stealing the frog from her, but after examining the footage, she caught the frog and deliberately incapacitated it, although she did not eat. She was holding the frog for her young otter to come and catch it from her.

An Otter’s whiskers are extra sensitive; the long whiskers have evolved to aid in hunting underwater. NA River otters are near-sighted, possibly as a result of underwater hunting.

A family of otters is called a “romp.”

Cape Ann’s growing Otter population is a clear sign that our waterways are in good health. North American River Otters are very sensitive to dirty water. Clean water, along with the expanded range of the North American Beavers, has helped create a welcoming habitat for River Otters to dwell and to breed.

Mom continually checks the landscape for pending danger. At the slightest hint of disturbance, underwater they all go. A NA River Otter can last up to four minutes underwater.

An Otterly Delicious Breakfast!

The North American River Otter is making an amazing comeback, not just on Cape Ann and all around Massachusetts, but in many regions throughout the United States. River Otters need unpolluted wetlands, streams, rivers, and ponds to survive, along with secluded places to den. Hollows in the banks of ponds and rivers make excellent dens and so do former Beaver lodges. As the perpetually-lodge-building Beaver has returned, so has the North American River Otter.

River Otters also need plenty of prey. Locally, they eat fish, frogs, snakes, and EELS!

This summer over in West Gloucester there appeared to be two Otter families, one mama with three pups and another mama with four pups. After watching the romp of Otters eat tadpoles and frogs early in the summer, by midsummer they had graduated to American Eels. I at first could not figure out what they were doing skirmishing around in the tall grass at the pond bank. Compared to diving and resurfacing with a mouthful of frog, this was entirely new behavior. There was much excited chortling when one of the pups caught an eel, which then seemed to set off a chain of eel ambushing and eating. One morning I had the great fun of observing three otter siblings chomping down on an otterly delicious breakfast!

First one pup catches an eel and brings it to the old wooden perch, which is also the otters favorite place to play hide and seek with each other.

Then the second pup, and soon all three were chowing down on eels!

The first one was getting jostled by his siblings and sought out more private room in which to dine.

American Eels can grow up to five feet long and weigh as much as 16 pounds. These Eels were about three to four feet long. American Eels spend most of their lives in freshwater and only return to saltwater to spawn and then die.

The pups deftly use their feet to hold fast the slippery eel.

Photographed on a different day, I think this pup is eating a snake. Notice the tapering tail in the above photo.

Why is clean water so vital to the survival of River Otters? Pesticides, industrial pollution run off such as polychlorinated biphenyls (PCBs), and mercury are absorbed by the River Otters prey. The chemicals accumulate in the River Otters, causing illness and death.

GOOD MORNING! BROUGHT TO YOU BY FAT AND FURRY CAPE ANN RIVER OTTERS

Soulful eyes of River Otters.

What a treat to come upon this North American River Otter family foraging along the pond’s edge. They are quite shy and mine was a brief encounter, but I hope to meet up with them again soon.

River Otters are returning to Massachusetts for several reasons, including better wetland conservation, pollution control, and the fact that the remarkable comeback of North American Beavers has also helped NA River Otters. For the few short moments that I saw the otters, the youngsters were playing with each other, while also intently feeding on frogs and tadpoles.
