3 Shy Creatures of Massachusetts

There are some species of wildlife we can see almost every day–from a rabbit munching on plants to a squirrel climbing a tree. Others, like the bobcat, fisher, or coyote, are a bit more elusive. Learn more about each of these shy creatures and what to do if you do encounter one. 

Only Wild Cat in Massachusetts

Bobcats, marked by their short “bobbed” tail, live in a range of habitats, with the highest populations in the central and western regions of Massachusetts. They’re roughly twice the size of a domestic house cat (from 15 to 35 pounds) but still smaller than most other wild cats found in the US.

Even though these cats are very wary of humans, small pets, livestock, and chickens can be on their diet. If there’s sightings in your area, be sure to keep your animals in a secure pen or indoors at night. If you see one in the wild, make sure you keep your distance and appreciate them from afar.

Weasels That Don’t Actually Fish

Despite being called “fisher cats,” fishers aren’t feline nor do they catch fish. Fishers look like most other weasels, with a sleek body (from 32-40 inches) and a long tail that makes up a third of their total length. These predators are equipped with retractable claws to help them hunt on the ground and roost in tall trees.

In the late 19th century, fishers were almost completely eliminated from southern New England because of forest destruction and unregulated trapping. After reintroduction to Massachusetts in the 1950s, fishers are now widespread across the state.

They prefer to keep their distance from humans but can attack free-roaming domestic birds, cats, and rabbits. They are also one of the only natural predators to eat porcupines. To help avoid fisher conflicts, make sure to clean the seeds below birdfeeders (which may attract small rodents), secure your garbage, and keep your pets and livestock enclosed at night.

Not Your Average Canine

Eastern Coyotes are a resilient species that have adapted to live in almost any landscape, including cities. These canines look like medium-sized dogs (23-26 inches tall) but have longer and thicker fur.

You can hear coyotes howling and yipping at night all year round, as they don’t hibernate. Coyotes are opportunistic feeders, meaning they will eat whatever food is available, including small animals, birds, garbage, and compost.  

Although the chances of being attacked by a coyote are slim, there are some simple precautions to keep you and your pets safe. Never approach or feed a coyote, and keep your garbage secured to prevent access. If you do come across a coyote, make lots of noise to scare it away.  

Protecting All Wildlife 

Mammals like bobcats, fisher, and coyotes may not be seen on a daily basis, but they still play a critical role in balancing their ecosystem by keeping other animal populations in check.

City Living for Trees

In the mix of a bustling city lined with buildings and people, it can be a welcome sight to see the blossoming branches of a tree in a local park or along a sidewalk. These trees are a bit different from the ones populating a more rural forest and face unique challenges. Mass Audubon’s first urban ecologist, Erica Holm, shares some of the thoughts and considerations that play into urban forestry.

Not Just Branches and Trunks 

Forget Spiderman and Superman: trees are the superheroes of concrete jungles, benefitting public health by storing carbon, absorbing and filtering stormwater, improving air and soil quality, preventing erosion, and adding biodiversity and wildlife habitat to our neighborhoods. 

Urban forests also keep cities cool. Many populated areas, often environmental justice neighborhoods, experience the urban heat island effect, a phenomenon where temperatures are significantly higher than in less-populated natural landscapes. These higher temperatures can have significant implications for public health and the lives of local residents. 

Role of an Urban Ecologist 

Erica Holm

Before each new urban tree is planted, there are numerous factors that an ecologist needs to consider.

What species is the tree, or what tree species would do best given specific site conditions? How tall will the tree get? Will it interfere with any existing infrastructure? Will pollen, seeds, or deciduous leaves be produced? Who will revisit the tree to water it during the establishment period (3-5 years after planting), and ensure its maintenance in other ways?

“Urban forestry is a hard field,” said Holm. “We can’t just plant a tree and walk away, expecting it to survive. We are asking urban trees to live in some of the most challenging conditions possible–unnatural levels of de-icing salt from roads and other pollutants, infrastructure barriers to growth, areas where storm damage needs to be monitored and cleaned up due to public safety, and a lack of natural plant communities and hydrologic function.” 

It’s also not just about planting new trees. Preserving existing trees is just as important. Trees on whole have much longer, slower lifespans than humans. Both new and old trees play a part in the city’s future in terms of ecology and resilience.

Supporting Your Trees

There are actions you can take right now to protect urban green spaces. If you want to plant a tree, first ask your local certified arborist or tree warden well in advance (at least one growing season) of when you want to plant, or get involved with the Department of Conservation and Recreation (DCR) Urban and Community Forestry Program. You can also volunteer at one of Mass Audubon’s wildlife sanctuaries to plant not just trees, but also pollinator plants and shrubs.
