Red Fox
There are many different species of foxes such as the Red fox, Gray fox, Arctic fox, and Fennec Fox and many more. Here in Massachusetts we only have Red, and Gray foxes.
Foxes typically have about 4 pups whom don't venture outside the den until around a month old, by the time they're 3 months old they're already learning to hunt.
Red and Gray foxes are omnivores so they eat both plants and meat. Red foxes measure about 35-40 inches from the tip of their nose to the tip of their tail and weigh around 7-15 pounds. Gray Foxes Measure about 31-44 pounds and weigh about 7-13 pounds. Similar to cats, Red foxes vertical pupils to enhance night vision for hunting and Gray foxes can climb trees.
If you do not want a Fox friend taking residence on your property close off crawl spaces they could potentially make a den in, and cut back any bushy edges as they use them for cover when hunting. Cats and dogs may not be a Foxes prime source of food but nonetheless they may still view them as food so keep an eye on them when they're outside and do not feed them outside as it may attract predators.
Do not let a fox intimidate you, they are just as scared of you as you are of them, if not more.
The eastern coyote may look a bit like a dog, but I assure you it is not. Their coats are typically grizzled gray but can also be red, creamy blonde, or an almost solid black. Females typically weigh around 33-40 pounds and males typically weigh around 34-47 pounds. A very large male can weigh 60 pounds! Coyotes have thick fur that often make them look bigger then they are.
A pair of Coyotes territory can range anywhere from 2 to 30 square miles. Breeding season is at its highest mid February. In April or May they give birth to 4-8 pups. Late Autumn the pups leave their parents also known as "disperse" to find a mate for themselves.
Coyotes are Opportunistic feeders/Omnivores. They scavenge a lot and are known to kill cats and small dogs. During the day coyotes are known to come out in search of food especially after they have pups.
Coyotes communicate with one and another by vocalizing, scent marking, and through body language. When hearing coyotes howling its typically just a few adult coyotes and their pups. Contrary to popular belief coyotes do not howl to announce a kill for this would attract other wild animals. Some reasons a coyote may howl are may be because they are looking to mate, telling other coyotes to stay out of their territory, looking for family members with in their territory, trying to distract a predictors away from their den site to protect their pups. You may also hear pups practicing howling typically in late summer.
Eastern Cottontail
In Massachusetts we have the Native New England Cottontail and the non-native Eastern Cottontail which where introduced into the state before 1900 and New England cottontail are much rarer these days because of the competition. They look very similar however some key differences are New England Cottontails have a darker back and typically a black spot between their ears, where as Eastern Cottontails have a paler coat, Cinnamon rust nape and a white or light brown spot on their forehead.
They are most active between dusk and dawn. They are solitary animals. They communicate with with soft grunts and purrs and thump the ground with their hind feet. They can scream a bloodcurdling scream when caught by predators. They eat any vegetation they can find.
They mate as early as February and as late as September. They give birth after 30 days to an average of 5 babies. The mother finds a rock, hole or digs a shallow hole in the ground known as a "scrape" and lines it with several layers of fur grass, leaves, rabbit droppings and sometimes paper or other trash. Baby Rabbits are born completely helpless but are outside the Scrape exploring by the time they're 2 weeks old and by the time they're 4 weeks old they are completely independent.
In Massachusetts we have White-tailed deer. An adult male deer also known as a buck weighs a 100-250 lbs and is 3.5-4 feet tall. Their antlers main branch is about 30 inches long and with twines that grow upwards every few inches. Adult female deer also known as a Doe weigh around 70-150 lbs.
Their coats changes through out the year, in the summer they have a reddish brown on top and white underneath. In the winter they are a grayish-brown with longer hollow hairs to help with insulation. Baby deer also known as a Fawn are a chestnut brown color with white spots. These spots disappear when they reach 3-4 months old after their first molt. Deer's are herbivores which means they eat a large variety of plants. They usually feed at dawn or dusk.
Bucks and Does live in separate groups except during rutting season which takes place during fall. Groups of Bucks will disband in August and September in search of Does, they usually mate in November or Early December and then return back to their maternal groups. Fawns are usually born in May or June and are hidden in the grass alone for the first week except when the mother returns to nurse. They stay with their mother for about 2 years before going off to find their own group.
Raccoons live throughout most of the United States and Southern Canada in wooded areas near water sources. Raccoon's are omnivores, so they eat both plants and animal matter. They aren't picky and can often be found raiding garbage cans at night.
Mating season is at its highest point January through March. Females only let the males around during mating season because males can be aggressive towards the young. The mother will find a nest which is often in a hollow tree, chimney or another similar spot. They typically have 2-5 young who are immobile and stay in their nest for the nest for the first eight weeks while the mother is out searching to food. When they reach 7-9 weeks old the mother moves them to a new nest and they accompany her during the night and learn how to find their own food. They usually stay with their mother for the first winter and leave in the spring in search of their own territories.
In Massachusetts we have Eastern Chipmunks, they are in the Squirrel family, yes I said Squirrel. Eastern Chipmunks are diurnal, which means they are active during the day and may be found gathering and storing food in their burrows for the winter. Eastern Chipmunks have short dense fur that is a reddish rust color on top and five black striped on their back,one going down the center and two on each side outlined by a white stripe. They have white eyeliner below each eye. Their body is 5-6 inches long with a tail that is 3-4 inches long.
Chipmunks typically eat Seed, berries, buts and fruit but can also be found eating insects, insect larvae. snails, slugs, earthworms and occasionally birds, bird eggs, frogs and small snakes. They store their food in their huge cheek pouches before bring it to their burrows. Eastern Chipmunks usually mate twice a year, once March to early April and a second early June to mid July. The mother will raise the the young alone. The first litter is born in April and May and the second in July and August. Litters can range in 2-5 babies which are born hairless and blind. When the baby's reach 6 weeks old they venture outside the burrow but never go to far. When they're 6-7 weeks old the mother becomes more aggressive toward her baby's to help prepare them to be independent, and by 10 weeks the mother kicks them out and the young are forced to disperse on and find or dig burrows of their own. You may hear a loud chirp during this time, this is presumably to let the young know of occupied territory.
During the winter chipmunks enter a torpid state, where their body temperature and heartbeat decreases and they wake up every few days to eat the food they gathered during the fall and defecate. In Massachusetts the enter their burrow late October and emerge March or April.
The entrance hole of a chipmunks burrow is about 2 inches in diameter goes down around 2 feet then parallel to the surface for up to 10 feet for the individual chambers Similar to human houses a Chipmunks burrow is composed of multiple chambers for sleeping, storing food, defecating, and giving birth. After the chambers are complete they use the dirt to plug the working tunnel and make a new entrance hidden near stonewalls, fallen trees or rocks, that are unnoticed by predators.

In Massachusetts have Gray Squirrels, They are very adaptable and live just about everywhere here. They range from 17 to 20 inches long and have have big fluffy tails that are almost have their body length that help keep them warm. The most common coloring is gray with a white underside but some can be white, brown or even black. We also have American Red Squirrels which are smaller then Grey Squirrels, typically about 12 inches long and have a white ring around their eyes. Northern and Southern flying squirrels are also here but only come out at night. They range from 10-15 inches and can launch them self 10+ feet through the air. Squirrels move quickly on the ground and through trees and can navigate all sorts of surfaces. They can jump 6 feet straight up or launch themselves 10+ feet from a tall surface.
They rarely live longer then 4 years because of predators. They eat nuts, flowers, buds and more. They mate twice a year, once in January or February, those young are born in March or early April, and again in August or September. Their eyes open around five weeks old and they tend stay with their mother till the next litter.
Squirrels have 2 nests, one in the trees made out of twigs that they use in the summer. These nests are sometimes also sometimes used in the winter if there is a food source nearby but they prefer to use a more permanent, protected den in the cavity of an alive hardwood tree or in the attic or eaves of a house.
