Well hello there little mouse! My husband Tom was releasing a mouse that was caught in his have-a-heart trap. He first opened opened the front door of the trap, with no sign of movement within, and then the back door. After a few minutes passed, out ran the little mouse, but then he froze in his tracks, only several feet from where I was standing. As I was motionless taking his photo, I think he must have thought I was a tree. He suddenly ran up my leg, up under my dress, and poked his head out from beneath my coat. It’s too bad I was holding the camera and not my husband!
Thinking about hantavirus, as well as other diseases mice carry, and just to be on the safe side, I changed my clothes and washed immediately.
Off towards the woods he ran.
Studies show how the increasing Eastern Coyote population has impacted White-footed Mice, Red Fox, and the explosion of Lyme disease. In areas where the Eastern Coyote has outcompeted the Red Fox for habitat, Lyme disease has increased. Coyotes not only kill Red Fox, they simply aren’t as interested in eating mice as are the fox.
Answer: Both the White-footed and Deer Mouse carry hantavirus, not the House Mouse. To be on the safe side, if you find rodent droppings in your home or office, do not vacuum because that will disperse the virus throughout the air. Instead, wipe up with a dampened paper towel and discard.
Cape Ann provides welcome habitat for a menagerie of creatures beautiful, from the tiniest winged wonder to our region’s top predator, the Eastern Coyote. Last year I posted a Cape Ann Wildlife Year in Pictures 2016 and I hope you will find the wildlife stories of 2017 equally as beautiful. Click on the image to find the name of each species.
Winter: Only partially frozen ponds allowed for dabblers and divers such as Mallards, Mergansers, and Buffleheads to forage at the freshwater. Mr. Swan had his usual entourage of quwackers and daily heads to the other side of the pond to get away for his morning stretches. Sightings of Red-tailed Hawks and other raptors abounded. Although photographed in Newburyport, the owl photos are included, well, just because I like them. An Eastern Screech Owl (red-morph) was seen daily perched above a playground and Barred Owl sightings too were reported throughout the winter. Raptors live on Cape Ann all year round but are much easier to see in winter when the trees are bare of foliage.
The beautiful green eyes of the juvenile Double-crested Cormorants were seen wintering at both Niles Pond and Rockport Harbor. And during a warm February day on a snowless marsh a turkey bromance shindig commenced.
In early spring, a male and female American Wigeon arrived on the scene making local ponds their home for several weeks. In the right light the male’s electric green feathers at the top of his head shine brightly and both the male and female have baby blue bills.
Meadow and marsh, dune and treetop were graced with the heralding harbingers of spring with photos of a Red-winged Blackbird, a pair of Cedar Waxwings, Northern Mockingbird, Brown Thrasher, Eastern Towhee, Eastern Kingbird, Tree Swallow, and Grackle included here.
The Great Swan Escape story made the news in Boston as Mr. Swan eluded captors for hours. He had re-injured his foot and someone took it upon themselves to call the animal rescuers, which would have surely meant death for our beloved 27-year old swan if he had been wrangled into captivity.
M is clearly for Migration through Massachusetts and the month-long arrivals and departures did not abate. Short-billed Dowitchers, winsome Willets, Yellow Legs, and Ruddy Turnstones are just some of the migrating shorebirds spied on Cape Ann beaches and marshes. The best news in May was the return of the Piping Plovers. Of the five or six that camped at Good Harbor Beach to investigate potential nesting sites, one pair bonded and built their nest mere yards from the nesting pair of last year. Could it be the same pair? The nesting Piping Plover story took up much of the spring and by early summer four little Piping Plover chicks hatched over Fiesta weekend. Hundreds of photos and hours of film footage are in the process of being organized with a children’s book and documentary in progress.

The survival of one Piping Plover chick was made possible by a wholesale community effort, with volunteers covering all hours of daylight, along with Mayor Sefatia and her team, Ken Whittaker from the conservation office, Chief McCarthy, and animal control officer Diane Corliss all lending a hand.
Sadly, several Northern Gannets came ashore to die on our Cape Ann beaches, struck by the same mysterious and deadly disease that is afflicting Northern Gannets in other regions. During the summer season they are typically at their North American breeding grounds, which are six well-established colonies, three in the Gulf of St. Lawrence, Quebec, and three in the North Atlantic, off the coast of Newfoundland.
An orphaned swan was introduced to Niles Pond, much to the dismay of Mr. Swan. Eastern Point residents Skip and Lyn kept watch over the two while they reluctantly became acquainted.
By mid-July many of us were seeing Monarchs in much greater numbers than recent years. Nearly every region within the continental United States experienced a fantastic Painted Lady irruption and butterflies of every stripe and polka dot were seen flitting about our meadows, fields, and gardens.
The tadpoles and froglets of American Bullfrogs and Green Frogs made for good eating for several families of resident otters, who are making their homes in abandoned beaver lodges. Little Blue Herons too, find plentiful frogs at our local ponds.
In early August we see the Tree Swallows begin to mass for their return migration. They find an abundance of fruits and insects in the dunes, headlands, and beaches. The Cedar Waxwings and Ruddy Trunstones were back again observed foraging on their southward journey, along with myriad species of songbird, shorebird, diver, and dabbler.
Tree Swallows Massing
The Late Great Monarch migration continued into the fall as we were treated to a wonderfully warm autumn. Waves and waves of Monarchs came ashore and more butterflies arrived on the scene including new batches of Painted Ladies, Clouded Sulphurs and Common Buckeyes (nothing common about these beauties!).
A pair of Northern Pintails called Cape Ann ponds and coves home for nearly a month while we seem to be seeing more and more raptors such as Red-tailed Hawks, Osprey, Bald Eagles, and Peregrine Falcons. Juvenile herons of every species that breeds on Cape Ann lingered long into the fall—Black-crowned Night Herons, Yellow-crowned Herons, Great Blue Herons, Snowy Egrets, Great Egrets, and Green Herons.
Just as Mr. Swan and the Young Swan appeared to be warming to each other, the Young Swan, who has yet to learn to fly, became trapped in the ice at Niles Pond. He was rescued by caretakers Lyn and Dan and is now spending the winter at a cozy sanctuary built by Lyn and friends.

With its expansive marshes and dunes, bodies of fresh clear water, saltwater coves and inlets, and geographic location within the Atlantic Flyway, 2017 has been a banner year for Cape Ann’s wild and wonderful creatures. I can’t wait to see what awaits in 2018!
Snowy Owl “Hedwig” January 2018 Backshore Gloucester
When out filming for projects, I’d often thought about what my reaction would be if ever again I came eye to eye with a coyote. Many have crossed my path, but too quickly and too unexpectedly to capture. I don’t bring my dog with me any longer because one brazen one had a go at her two winters ago and it’s just not a good idea to tempt fate. I hoped that calmness would prevail, allowing for a non-blurry photo, or two.
Well, I didn’t panic and got some great footage, and when the coyote was too far out of range for my movie camera, took a few snapshots.
This one appears smaller than what I have typically encountered, perhaps it is only a year or two old, or possibly coyotes are not as plump after the winter months. He/she was very intent upon scavenging in a bed of seaweed that had washed ashore and think it must have been quite hungry to allow me to get so close. He reluctantly left his meal as I moved toward him and then watched me for some time from under cover of beach grass. His shining eyes were easily seen in the fading low light. Mistakenly, I thought that was the end of our meeting and went back to filming B-roll.
Beach grass provides excellent camouflage
I was losing the light and decided to call it a day. Packing up cameras and turning to go, there he was, a hundred yards away, staring at me. Deftly traveling through the tall reeds he had circled around. I don’t think he had me in mind for his next meal, but I was halfway between him and the scavanged dinner from which he had so rudely been interrupted. Plans on how to weaponize my tripod and camera bag quickly came to mind. He trotted leisurely towards me, changed his mind, and then trotted in the opposite direction. A car came down the road and he again turned toward my direction, making his way along the beach until slipping back into the grass.
If ever you have a close encounter with a coyote, be sure to remind yourself of this story and know that they may indeed still be very close by.
Are Coyotes the Cause of an Increase in Lyme Disease?
Struck by the recent interest in coyotes after the fascinating video Two Coyotes Versus One Deer by Shawn Henry was posted on GMG, I became interested in reading various studies and reports about coyotes, wolves, and foxes in Massachusetts and the Northeast. My primary interest at the onset was of concern for the Red Fox (Vulpes vulpes), which has seen a tremendous decline in numbers. I wondered if the presence of coyotes (Canis latrans) was negatively impacting the Red Fox. In the past, I often saw a Red Fox in the early morning hours trotting along the shoreline at Brace Cove. I wish so much that I had filmed the last that one that I saw because it was a gorgeous scene; a strikingly beautiful creature so completely unaware of my presence and so at home in its realm, investigating rock and seaweed, pausing to sniff the air, and then resuming its journey. The last time I saw a Red Fox in our neighborhood was over three years ago. As I was reading about coyotes I learned the findings of some of the most recent studies indicate that because Eastern Coyotes out-compete the Red Fox, the coyotes are the cause of an increase in Lyme disease. More on that in a moment.
The coyotes that now inhabit every region in Massachusetts are an invasive species. They are a hybrid cross species of the Western Coyote (found west of the Mississippi) and Red Wolf (Canis lupus rufus). “Researchers now believe that the Eastern Coyote is a hybridization between the Western Coyote and Red Wolf many generations ago in the upper Great Lakes region of the United States. It is theorized that as populations of the Western Coyote increased, they were forced to move east and north in search of food. As they moved into Minnesota they crossbred with Gray/Red Wolves and produced a genetically hardy animal able to sustain itself through New England winters.” (Mass Audubon)
Coyotes are not “re-populating” this region because this new species was never in our region.
Eastern Coyotes have extremely broad food habits and many factors affect the coyotes’ diet, including competition with other mammals, abundance of prey, season, and weather. In the Northeast, their diet consists of shrews, rabbits, voles, woodchucks, mice, deer, beaver, muskrat, weasels, squirrels, and carrion. And according to Mass Audubon, “They eat ground-nesting birds and their eggs, as well as reptiles and amphibians. When other prey is scarce they will eat a variety of insects including grasshoppers, beetles and cicadas. When animal matter is scarce, they will eat available fruits including apples, cherries, grapes, and strawberries.”
The rapid invasion of the alien Eastern Coyote has negatively impacted many sympatric native species, as the coyote has assumed the role of top-order predator. The coyote has fundamentally altered the existing ecosystem and various species have experienced population declines as a direct result of their role as coyote prey or from direct competition for food. “Culturally and ecologically significant species including Red Fox decline dramatically in response to increasing coyote populations. Eastern Coyote and Red Fox share many common habitat requirements and occupy overlapping niches. Through time, the larger and more resilient coyote is able to out-compete and displace resident fox populations.” (Department of Natural Resources, Maryland.)
Studies have shown repeatedly that Eastern Coyote predation on deer is minimal. Most herds can handle the coyotes. Typically coyotes have success with fawns that are 4-5 weeks old (after they have become more active and are not by the mother’s side), weakened and sickly adults, and deer separated from the herd. These targets represent approximately one or two percent of the total deer population. While coyote diet studies show consistently the use of deer for food, it does not appear that coyote limit deer population on a regional scale.
Although the population of White-tailed Deer has stabilized, Lyme disease continues to increase. In June of 2012 researchers at the University of California Santa Cruz published their findings from the study “Deer, Predators, and the Emergence of Lyme Disease.” (Taal Levi, lead author.)
The study found that once where there was an abundance of Red Foxes, there is now an abundance of Eastern Coyotes. Even more significantly, fewer coyotes will inhabit an area once populated by more foxes. The greater number of foxes would have consumed a larger number of small tick-bearing animals, primarily White-footed Mice, Short-tailed Shrews, and Eastern Chipmunks, all of which transmit Lyme disease bacteria to ticks. It appears as though it is the Red Fox that once kept the population of these smaller rodents under control.
Even when there is a threefold rise in deer population, study after study now shows that the strongest predictors of a current year’s risk of Lyme disease are an abundance of acorns two years previously. How does that work?
Many acorns = many healthy mice and chipmunks.
Many healthy mice and chipmunks = many tick nymphs.
The following year when it may not be a bumper acorn crop = fewer mice.
Fewer mice and chipmunk = dogs and humans become vectors for the ticks.
While acorns don’t serve as a universal predictor because Lyme disease can be traced to forests where there are no oak trees, the data suggest that food sources and predators of small forest mammals are likely to be valuable in predicting Lyme disease risk for humans.
To summarize, multiple studies suggest that the invasive Eastern Coyote out-competes and kills the native Red Fox population, which leads to a rise in the number of small animals particularly the White-footed Mouse and Eastern Chipmunk, which in turn leads to an increase in ticks that carry Lyme disease. The impact of the Eastern Coyote on native deer population is negligible. And, as many family’s can attest, the impact of the Eastern Coyote on populations of domestic cats and small dogs has been devastating.
Typically the excuse given for unwanted encounters with wildlife is that people are encroaching on the animal’s habitat. That simply is not the case with the Eastern Coyote. The Eastern Coyote is advancing on humans–and they like what they see; no large predators, a reluctance on the part of people to hunt and trap, and an abundance of food. The environmentally and culturally destructive chain reaction caused by the Eastern Coyote invasion is taking on added urgency as the coyote strikes closer and closer to home.
If confronted by a coyote, make as much noise as possible, if attacked, fight back aggressively.
