Groundhog day was a little over two months ago. However, this is the time of year when they usually start to make their appearance, emerging from their dens following a long winter of hibernation. Until last Monday – when winter reared its ugly head, once more – it looked as if we would be seeing these little rodents soon. They may have rethought their intentions, and gone back to sleep.

Groundhogs, Marmota monax, also known as woodchucks, are a rodent, belonging to the group of large ground squirrels known as marmots. It was first scientifically described by Carl Linnaeus in 1758.

The groundhog is also referred to as a chuck, woodshock, groundpig, whistlepig, whistler, thickwood badger, Canada maramot, monx, moonack, weenusk, red monk, and, among French Canadians in eastern Canada, siffleux, which translates to whistler.

They are a lowland creature, found through much of the eastern United States across Canada and into Alaska. Adults are 16 – 20 inches long, including a six-inch tail, and weigh between 5 – 12 pounds. Extremely large individuals can weigh as much as 15 pounds.

The name woodchuck is unrelated to wood or chucking. It stems from the Native American Algonquian or possibly Narragansett word for the animal, wuchak. The similarities in the name led to the popular tongue-twister: “How much wood would a woodchuck chuck if a woodchuck could chuck wood? A woodchuck would chuck all the wood he could if a woodchuck could chuck wood.”

Groundhogs prefer open country and the edges of woodlands, and is rarely far from a burrow entrance. It is typically found in low-elevation forests, small woodlots, fields, pastures and hedgerows. It constructs dens in well-drained soil, and most have summer and winter dens.

In the wild, groundhogs can live up to six years, although three years is the average. In captivity, they can live up to 14 years. Humans, dogs, coyotes and foxes are about the only predators that can kill adult groundhogs, with the red fox being the major predator. Young may be taken by owls and hawks.

According to studies, despite their heavy body weight, they are accomplished swimmers and will occasionally climb trees to escape a predator. They prefer to retreat to their den when threatened, and will defend themselves with their incisors and front claws. They are territorial among their species and will skirmish to establish dominance.

When alarmed, they will use a high-pitched whistle to warn the rest of the colony, hence the nickname whistlepig. They will also squeal when fighting, seriously injured, or caught by a predator. They will also produce a low bark and a sound produced by grinding their teeth.

They are excellent burrowers, using the burrow to sleep, rear their young, and hibernate. An excavated den can remove about six cubic feet of soil, on average, or almost five bushels per den. They are relatively large and include a sleeping berth and an excrement chamber.

The burrow can be a threat to agricultural and residential development by damaging farm machinery and even undermining building foundations. However, in a June 7, 2009, issue of the Humane Society of the United States, How to Humanely Chuck a Woodchuck Out of Your Yard, John Griffin, director of Human Wildlife Services wrote, “you would have to have a lot of woodchucks working over a lot of years to create tunnel systems that would pose any risk to structures.”

The burrow is used for safety, retreat in bad weather, hibernating, sleeping, love nest, and nursery.

Groundhogs are one of the few species that enter into true hibernation. In most areas they hibernate from October to March or April. They drop their body temperature, the heart rate falls to 4 – 10 beats per minute and breathing falls to one breath every six minutes. Researching the hibernation patterns of groundhogs may lead to benefits for humans, including lowering the heart rate in complicated surgical procedures.

Groundhogs are already used in medical research on hepatitis B-induced cancer. Humans can’t receive hepatitis from woodchucks but the virus and its effects on the liver make the woodchuck the best available animal for the study of viral hepatitis in humans. The only other animal model for hepatitis B virus studies is the chimpanzee, which is an endangered species.

Always thought to be a nuisance species, groundhog dens often provide homes for skunks, red foxes and cottontail rabbits. The fox and skunk feed upon field mice, grasshoppers, beetles and other creatures that destroy farm crops. In aiding these animals, groundhogs indirectly help the farmers.

Well, I had a groundhog living near my garden a few years ago, and he unceremoniously cleaned out all my string beans. Well, I unceremoniously captured him in a Hav-a-Hart trap, and relocated him to the wild, and wished him the best of luck.

Before Mookie Betts, who was the last Boston Red Sox player to win the American League batting title?

An era has ended in New England. Heck, it has ended throughout the United States. Rob Gronkowski, the happy-go-lucky, larger-than-life, bruising tight end for the New England Patriots has announced his retirement following nine seasons in the National Football League. Patriots fans lament his decision, while the rest of the league breathes a collective sigh of relief now that they don’t have to deal with the constant downfield threat.

I met Gronk once, right after his rookie season. A massive human being with a jovial personality, his hand enveloped mine and almost crushed every bone during a vigorous and aggressive handshake. I lost that one. I have met many professional sports athletes, but the encounter with Gronk is one that comes to the forefront of memories.

Chosen in the second round of the 2010 draft, the 42nd player picked overall, Gronk went on to a stellar career. The 6-foot 6-inch, 268-pound tight end amassed 521 career receptions, 7,861 receiving yards and 79 receiving touchdowns as a player. Along with that, he played on three Super Bowl-winning Patriots teams, was chosen to five Pro Bowls, four-time All Pro, and NFL comeback player of the year in 2014. He is a shoe-in for the NFL Hall of Fame.

With the many accomplishments and accolades, Gronkowski is regarded by many sports analysts, writers and peers as not only one of the the finest players in the league, but the greatest tight end to ever play the game.

But, the position of tight end was revolutionized a long time ago by another Patriots player.

Russ Francis, a 6-foot, 6-inch, 242-pound tight end with the Patriots, changed the position’s importance back in the 1970s.

Drafted out of the University of Oregon in 1975, in the first round, the 16th overall pick, he went on to become the premiere tight end of his era. He played seven seasons with the Patriots and six seasons with the San Francisco 49ers, where he was a member of the Super Bowl XIX champions in 1984.

During the 1976 season, in the Patriots 30-27 victory over the Pittsburgh Steelers, the defending Super Bowl champions, Francis caught a 38-yard touchdown pass from Steve Grogan on a fourth and one. In that game, Francis had a career-best 139 receiving yards, prompting sportscaster Howard Cosell to proclaim him as the “All-World Tight End.”

Francis was a Pro Bowl selection for three consecutive seasons from 1977-79.

However, many years prior to Russ Francis coming onto the scene, there was another man who made a mark as a tight end in the NFL.

Mike Ditka arrived in the National Football League in 1961 out of the University of Pittsburgh. The 6-foot, 3-inch, 228-pound Ditka was nicknamed “Iron Mike,” perhaps because he was born and raised in a steel town in Pennsylvania. But Ditka had a nasty side to him that shook the league. He was the fifth pick overall in the 1961 college draft, by the Chicago Bears. He had the distinction of having been picked in the first round of both the NFL, and the American Football League, rival leagues at the time.

In his inaugural season in the NFL, he had 58 receptions, introducing a new dimension to a tight end position which had previously been dedicated to blocking. He was selected rookie of the year. He went on to play for the Philadelphia Eagles and Dallas Cowboys, and was inducted into the Pro Football Hall of Fame in 1988, becoming the first tight end to do so. Ditka totaled 4,503 yards (ranking him first in Bears history), 316 receptions and 34 touchdowns.

When his playing days were over, he became an assistant coach with the Cowboys in 1972, where he was a member of the Super Bowl winning team, in 1977. From there he went on to coach the Chicago Bears, where he won a Super Bowl in 1986, becoming one of only two men to win a Super Bowl as a player, assistant coach and head coach. Mike Flores is the other. Ditka, Flores, Gary Kubiak and Doug Pederson are also the only people in modern NFL history to win a championship as head coach of a team for which he once played.

There are other tight ends around the NFL that are mentioned when discussions arise about the tight end position. But, in my opinion, these are the three that stand out as having the largest impact on the position from how it was once utilized, to the importance it now represents in the modern offensive schemes in the league. Gronk is, without a doubt, a member of an elite trio responsible for that.

This week, we’re going to move away from the animal world and take a look at some fauna.

Joan Chaffee, of Clinton, recently sent some photos of pussy willows she snapped while snowshoeing. She wrote, “I was snowshoeing this past Saturday, March 9, in our back field and came across these pussy willows. A sure sign of Spring!”

At the tail end of winter, fuzzy nubs start to appear along the branches of pussy willows. So, what exactly, are these little nubs?

They are actually flowers just before they fully bloom, and not seeds or fruits like they are perceived. The soft coating of hairs acts as insulation to protect these early bloomers from cold temperatures. The species most commonly called pussy willows in the northeast, Salix discolor, is a small, shrubby species of willow that can be found dotting wetlands and most woods throughout much of North America.

Their blooms, also known for their delightfulness, usually signal the last throes of winter.

The petal-less male flowers are covered with pollen-bearing stamens. Catkins, as they are called, usually don’t rely on pollinators to spread their pollen. Instead, they simply release it into the wind, where it may or may not land on the female flower parts. In order to hit their targets, the catkins must produce a tremendous amount of pollen.

Pussy willows are dioecious, meaning there are both male plants and female plants. Only the male plants will produce the fuzzy flowers. Some home gardeners become disappointed once they learn they have a female tree. The flowers are equally pleasing, but look more like greenish hairy caterpillars.

Most cut pussy willow stems are in a sort of time warp – dried at their peak fuzziness, and never allowed to fully flower. But if you keep fresh-cut pussy willows hydrated, you can see the whole flowering cycle and even the leafing-out process. It is important to get healthy-looking bunches (look for flexible, greenish stems that don’t feel brittle or look shriveled), and place in a vase near a window, changing the water daily. You can add a little flower food if you have some. Watch for new flower buds to cast off the shiny brown bud scales that surround the flower. When the flowers mature, you will see many yellow stamens emerge to cover each catkin. Wait even longer, and you may also see pale green, strappy leaves unfurl from the leaf buds. At this point, your willow stems will be in full spring growth and will need to be planted in soil outdoors to root. They may or may not take.

In films, pussy willows are featured in a key part of the film Serial Mom, as one character, Beverly Sutphin, begins leaving clues to her identity for her neighbor Dottie Hinkle.

In literature, Pussy Willow, a children’s book by Maraget Wise Brown (1951), tells the story of a gray “pussycat not much bigger than a pussy willow,” who names himself Pussy Willow after the catkins he finds around him in spring. When the catkins disappear with the passing of the season, he goes in search of them, asking each different kind of animal he encounters where he might find them. The animals all answer from their own perspective. “Up in the air,” says the butterfly; “under a leaf,” says the squirrel. Pussy Willow finally finds them a year later when spring comes around again.

Pussy willows get their name for their resemblance to tiny cats’ paws, and they feel so much like fur that young children often wonder if they are animals instead of plants.

So, with the sighting of pussy willows on March 9, it is a sure sign that spring is imminent. Let’s hope so.

ERMINE UPDATE

A friend of The Town Line recently told me of an incident she encountered in her own home. One day she opened the cupboard doors under her sink in the kitchen, and noticed these beady little eyes staring back at her. Startled at first, she stood motionless while the little critter stared back at her, neither moving for a moment. Finally, the little white ermine scurried off, probably from where it came.

As reported in this column in the February 14, 2019, issue, ermines, a/k/a weasels, have been finding their way into homes this winter. The first reports came from southern Maine. This recent sighting happened in China.

It seems to be a universal happening.

Roland’s trivia question of the week:

Which pitcher, originally drafted by the Boston Red Sox and traded to Baltimore before ever playing a game with Boston, returned for both of the Sox’ titles in 2004 and 2007?

A 40-year study conducted by the Audubon Society has found that more than half of 305 bird species in North America are spending the winter about 35 miles farther north than they did 40 years ago. Some of these birds include chickadees, robins and owls.

Bird ranges can expand for many reasons, among them urban sprawl, deforestation and the backyard feeders.

The study suggests that the reason so many birds over such a broad area are wintering in more northern locations is climate change.

The study of migration habits from 1966 through 2005 found that about a quarter of the species have moved farther south. But the number moving northward (177 species) is double that amount.

Of all the birds, the purple finch was the biggest mover. Its wintering grounds are now more along the latitude of Milwaukee, Wisconsin, instead of Springfield, Missouri.

Over the four decades covered by the study, the average January temperature in the United States rose by about five degrees. That warming was most pronounced in northern states, which have already recorded an influx of more southern species and could see some northern species move into Canada.

The study also provides support for what many bird watchers across the country have long thought – that many birds are responding to climate change by moving farther north.

Previous studies of breeding birds in Great Britain and the eastern U.S. have noticed similar trends. But the Audubon study covers a broader area and includes many more species.

Examples of these are the purple finch and the boreal chickadee. They are spending their summers in the forests of Canada and fly south into the U.S. for the winter. Climate change could be playing a role in why they are not flying as far south as they used to. This is reflected in the fact that these species of birds are no longer as common as they once were in states like Maine and Vermont.

The Audubon Society likes to conduct their bird counts in mid-December. At that time of year, temperature is the primary driver for where birds go and whether they live or die.To survive the cold, birds need to eat enough during the day to have the energy needed to shiver through the cold nights.

With the milder winters that the northeast has been experiencing in that four-decade span, it is possible that birds don’t need to expend as much energy shivering, and can get by eating less food in the day.

However, researchers cannot explain why some certain species are moving. It’s speculated that changes in temperature affect different birds in different ways.

Researchers don’t know for a fact that it is warming. But when they keep finding the same thing over and over, they reason that it is not just a figment of the imagination.

Over the past 40 years, the Christmas Bird Count has documented shifts to the north or inland for the majority and for nearly every kind of North American bird species. Audubon’s analysis confirms the evidence from bird enthusiasts who have frequently reported changing populations.

Given the strong evidence that global warming is indeed a key factor in documented bird movements, shifts like these will continue for familiar species — for better or worse — as long as the climate continues to change. Though these movements clearly point to significant ecological disruption underway, their short and long term impacts will vary for specific species and even groups.

Among all landbirds in the study, 64 percent showed significant northward movement, including more than 70 percent of all woodland birds and 70 percent of those that frequent feeders.

Among the birds that depend on feeders, such as Boreal Chickadee and Pygmy Nuthatch, have moved hundreds of miles since 1966. Already adapted to human surroundings, they are unusually well-suited to a shifting climate. Most will fare well in the short term, as long as food is provided to them. However, northern-wintering birds are highly vulnerable to the sudden onset of cold and stormy conditions. They are also likely to further disrupt ecosystem balance by forcing out less adaptable species.

Woodland birds that do not visit bird feeders, such as Spruce Grouse and Barred Owl, also showed long-distance northward movements. Their continued survival in northern winters will depend on healthy forest habitat, which is already at risk due to both the drying effects of global warming and over-development by humans.

Grassland birds are among the few groups that did not move north over the past 40 years, but are the most vulnerable. Only 10 of 26 (38 percent) grassland species moved north significantly, while nine moved south. Many probably could not move into northern areas despite increasingly moderate temperatures, because conversion to human uses such as crops, pastures, and hayfields, has greatly reduced availability of grassland habitat. These species are facing an uncertain future.

These little creatures of Mother Nature are wonderful to watch, track and photograph, as they go about their daily routines. In the process, they are trying to tell us something. We need to take note.

Roland’s trivia question of the week:

The NBA’s Memphis Grizzlies formerly played in what Canadian city?

Answer can be found here.

by Roland D. Hallee

In recent weeks, there have been numerous reports of incidences where weasels have found their way into homes. There were reports in Harpswell, Cumberland and Bangor.

The woman in Bangor said she noticed what she thought was a rat or an escaped ferret in her ceiling. It had been running around in the ceiling, so she removed one of the ceiling panels. When it poked its head out, she called the landlord and both determined it was someone’s escaped pet ferret. However, it was later determined to be a weasel, or ermine as they are also known.

Weasels are naturally very curious and do wander from time to time into people’s houses, perhaps in search of mice. Their small size allows them to get into nooks and crannies.

There was one instance when the homeowner captured the ermine in a humane trap, and before she even had it for a minute, the ermine escaped.

Ermines are common throughout Maine and hunt both night and day, but people don’t often see this small animal because it’s well camouflaged, moves fast and tends to keep out of sight.

Weasels are usually brown, gray or black with white or yellowish markings. All weasels become all white in the winter. The winter fur of the least weasel glows a bright lavender color when exposed to ultraviolet light.

Ermines are especially difficult to spot in the winter season, when their coat turns from brown to white, an adaptation that allows it to hide in the snow. The only thing that remains pigmented on an ermine is the tip of its tail, which is jet black.

As nocturnal animals, weasels sleep during the day and are active at night. Most of a weasel’s time awake consists of hunting, storing excess food and eating. Their bodies don’t store fat, so they need a constant supply of food to provide enough energy. In fact, the least weasel eats 40 – 60 percent of its body weight every day, according to the Nature Conservancy.

The most common weasel is the short-tailed weasel. It can be found in North America, Europe and Asia, in regions as far north as the Arctic. Their homes include marshes, scrubs, hedgerows, alpine meadows, riparian woodlands and riverbank habitats, according to the International Union for Conservation of Nature and Natural Resources (IUCN).

The genus includes least weasels, polecats, stoats, ferrets and minks. These animals are small, active predators with long and slender bodies and short legs.

According to Dr. Alessio Mortelliti, assistant professor in the University of Maine Department of Wildlife, Fisheries and Conservation Biology, “It’s pretty much anywhere in the world, plus it’s an invasive species in some places.”

Ermines are especially ferocious and bold. It is not uncommon for this predator to attack and kill prey that exceeds them in size and weight. For example, ermines, that weigh between 1.6 to 3.7 ounces, have been known to attack gray squirrels, which are much heavier, typically weighing between 12 and 24 ounces. Ermines are very aggressive, “they can go for prey that is bigger than them,” said Mortelliti. Ermines will attack young rabbits and hares, but they prefer smaller prey such as mice and voles. In fact, one of the ermine’s key adaptations is their ability to manipulate its flexible body into small tunnels that are created by smaller animals.

They are also bullies. Although they can dig their own burrows quite quickly, they sometimes take over another animal’s burrows and make them their own.

In Greek culture, a weasel near one’s house is a sign of bad luck, even evil, especially if there is a girl about to be married, since the animal was thought to be an unhappy bride who was transformed into a weasel, and consequently delights in destroying wedding dresses. However, in neighboring Macedonia, weasels are generally seen as an omen of good fortune.

In North America, Native Americans, in the region of North Carolina, deemed the weasel to be a bad sign: crossing its path meant a “speedy death.” According to Daniel Dafoe, meeting a weasel is a bad omen.

In the English language, being called a weasel is considered an insult, being regarded as sneaky, conniving or untrustworthy.

How do these animals find their way into homes? Usually through some openings in the foundation, broken windows or sometimes through openings in the roof like attic vents or chimneys.

How do you rid yourself of one? Use fresh meat, if possible. Position your bait strategically, so that the weasel must bring its entire body into the trap and step on the trigger plate to get to it. Make sure the bait is far enough from the trap walls that an animal cannot reach inside and steal it without entering. Weasels are known to bite, so wear heavy gloves whenever handling the trapped animal and refrain from sticking your fingers inside the trap.

Again, weasels are cute, but do not approach one unless it is safely in a Havahart trap, be careful handling it, and take it deep into the woods, where it belongs.
