Reston’s Red Fox population is alive and well, providing exciting wildlife encounters and comic relief for residents. Learn what’s in store for these adaptable small dogs and what challenges they face for the coming summer.

Our fox—a brief historyOf the 5 fox species in the world, the one with the red hair, Vulpes vulpes, is by far the most plentiful and wide-ranging. It is the sly adversary of Aesopian fables, the trickster Reynard of French-Canadian folklore, and the fox you can easily encounter right here in Reston. Despite the introduction of European Red Foxes for sport during Virginia’s colonial period, DNA research has shown that most of the matrilineal ancestry of eastern Red Foxes originated in North America.

The latest from your neighborhood fox denIn dens throughout our natural areas and possibly even in your backyard, fox pups (sometimes called kits or cubs) are taking their first breaths of air. Born deaf and blind in early March, they will spend the next two weeks in the leaf-lined nesting chamber snuggling with their mother. She will rarely leave their sides as her pups are unable to thermoregulate at this point. During this time, their father is the sole bread winner for the little family, bringing mice and small rodents for the mother as she nurses the young. Typical litter size is six although there may be as few as two or as many as 12.

After a month, the pups begin to emerge from the den. Their black newborn hair has begun to fade to a sandy grey color, which better matches the soil around the den where they will romp and play for the coming weeks. Continued on page 2

Pups in the Woods Continued from page 1

These first few weeks above ground are the most dangerous for the pups as they are the right size snack for cats, Coyotes and Great Horned

Owls. If a den is disturbed too frequently by predators or people, the parents will move their pups to a safer location. In some cases, foxes will

use the same dens for generations.

At ten weeks, the inquisitive pups begin to follow their mother out on hunting excursions. They will develop their stealth and sharp senses, essential in a few short weeks to locate prey from a distance without being noticed. For now, they will practice these abilities on their brothers and sisters, but soon it could be a matter of life and death. Stalking and pouncing skills are key to taking their prey by surprise.

By fall, roughly six months from their birth, the pups take on their adult coloration and are capable of fending for themselves. Although not fully grown, they will soon wander away from home to stake out territory of their own. Generally, male pups will be run off by their father early in the fall. Whereas some of the young females may stay in the den through the winter to help their mother with next year’s litter. During their first winter, young solitary foxes have to hunt and forage on their own. Foxes can be active at any time of day, but prefer to hunt at dawn and dusk when the light is in their favor. While small rodents, bugs and berries are favorite foods, foxes are opportunistic eaters when preparing to survive the cold months ahead.

Fox life—the hard truthMore than half of every litter will succumb to the elements, disease, predators, traps, or poison before reaching maturity. For those making it to adulthood, the average life span is three to seven seasons. You can help foxes by not feeding them on purpose or by accident. Don’t leave unattended pet food bowls outside and secure your trash in a can with a tight fitting lid. Feeding of wildlife can threaten human and animal safety. When foxes are fed, they begin to lose their instinctual fear of humans and become too comfortable in residential areas, sometimes appearing almost tame. These animals may be considered a nuisance, display aggressive behaviors and become dangerous.

This spring, watch for Red Foxes at the nature center, trotting across RA ballfields, taking a morning walk through The Glade Stream Valley or stalking gray squirrels in your own yard. These adaptable omnivores have a knack for making a life for themselves across the globe.

Reston’s Red Fox Facts• A Red Fox measures ~3 ft. long, including its luxuriant foot-long tail.

It stands 14-16” at the shoulders, and weighs a mere 8-10 pounds.• Healthy foxes are often active during the day. Habitat loss and competition from larger predators (i.e. Coyotes) have resulted in their more diurnal behavior.• Foxes are not known to attack cats or other domestic animals.

However, larger Coyotes WILL go after cats and small dogs. • Red Foxes reach speeds of nearly 30 mph and can leap more than 6’ high.• The Red Fox uses its bushy tail as a blanket to keep warm.

Stay ActiveBy Earl the Squirrel with help from Abby Stocking

Winter sure is quiet in my neck of the woods. That’s why I really look forward to spring and the buzz, hum and chirp it brings. Spring is the time of year when insects start to wake up from their winter naps. They bring nature’s music back to our ears, and they add to the color and fun of spring. Be on the lookout for some of my favorites.

• Ladybugs – In the winter, they crawl into cracks in trees or even into people’s homes where they sleep, sometimes in large groups. In spring, adult ladybugs crawl out to look for aphids and other small insects to eat.

• Mourning Cloak Butterfly – One of the first butterflies to wake up in spring, these lovely creatures really brighten my day. Many butterflies spend the winter inside an egg or in a chrysalis covering. But Mourning Cloaks survive as adult butterflies. After drinking some tree sap in early spring, they will lay eggs to create more of these beautiful creatures.

• Bumblebees – Only the young queen bees survive winter. They hibernate under the soil. In early spring, the queen wakes up to find nectar to eat and a place

for a new nest. She lays eggs in the nest and takes care of the baby bees that

grow up to be worker bees. The queen continues to lay eggs that

the worker bees will then help take care of.

Make Your Own Ladybug1. Cut out one section from a clean egg carton. (You may need an adult to help you.)2. Turn the piece of egg carton so that the bottom side is facing up. This will be its body. Color that side red.3. Add black dots to the ladybug’s body.4. Glue a black pom pom (or cotton ball) to one end of the ladybug’s body. This will be its head.5. Glue two googly eyes to the pom pom or draw eyes on the cotton ball.6. Make as many ladybugs as you want. Try using different colors or numbers of spots for each new one.

Native Spotlight: JACK-IN-THE-PULPIT(Arisaema triphyllum)By Sharon Gurtz

One of the more distinctive plants you may find while hiking in the spring woods is Jack-in-the-pulpit. Its structure and lifestyle are almost as unique as its name. Jacks can grow 6 inches to 3 feet tall. They have one or two large, glossy leaves, each on its own stem, divided into three leaflets—not to be confused with poison ivy.

If you pay attention to the flower structure you can recognize it every time. Look for a long, tube-shaped stalk that has a "hood" draped over it. The hood can be white, green, brown or purple. It can be a solid color or have a striped appearance. In the fall, bright red fruit, eaten by Wild Turkey and Wood Thrush, may be found on the center stalk after the leaf stems and hood have fallen off.

Why the name Jack-in-the-pulpit?The name comes from the distinctive shape of the flower-bearing stalk. The long, central club, called the spadix, is the “Jack”, and the leaf-like hood, also called a spathe, is the “pulpit”. The spadix extends above the bottom edge of the spathe suggesting the appearance of a country parson perched on an elevated stand over his congregation. The upper part of the spathe curves forward and downward acting as an umbrella to protect the preacher, also preventing water from flooding the 30-60 tiny flowers hidden at the base of the spadix. Other common names for this plant are Arum, Indian Turnip, Wild Turnip and Dragon Arum.

Jack-in-the-pulpit - or is it Jill?Can plants be male one year, and female the next? In the case of Jack-in-the-pulpit, the plant can control the number of female and male parts it produces. It appears to be male one year, and female another. In some years there are no flowers at all. Why would a plant change its gender from year to year? Apparently age and environmental conditions are key factors.

A young plant may not form flowers for 4-6 years. When the plant is large enough, the first flowers will be pollen-producing males. As years pass and the plant increases in size, the larger spadix will begin to produce female flowers. Female flowers can produce fruit and seeds. The sex of the current year’s plant will be determined by the size of the previous year’s root storage structure called the corm. When a plant uses its energy to produce berries, the next year its corm will be smaller and often will have male flowers. Environmental conditions that are less than ideal can also cause corm size to be smaller, with a change in sexual expression from female to male. There may be no flowers at all following a stressful year for the plant. This can be caused in part by drought, competition or even browsing by the local deer herd that decided it would make a tasty snack.

If you come across this plant in our woods, there is a fairly reliable way to distinguish female plants from males. In most cases, females will have 2 leaves (6 leaflets) and males only one (3 leaflets). If you look deep inside the spathe, and see a group of round green berries, you are looking at a female plant.

Native Americans are reported to have dried the corms and cooked them as food and also used the plant medicinally, but the corm is loaded with oxalic acid and the plant is considered to be poisonous. Raw root and stems can burn the mouth, swell the tongue and cause stomach distress. So, while Jack-in-the-pulpit may not make the best addition to your diet, it is still a beautiful plant that adds intriguing variety to woodland gardens. Find a moist-to-wet site in shade or part shade with plenty of organic material. Then, be patient. It can take several years to get flowers, but it is a very long-lived perennial that spreads easily by seed.

Next time you come across this native, or its relative skunk cabbage, in our woods or along the stream banks, remember how lucky we are to have natural woodland areas where we can view such unique plants. Better yet, observe it over the years to see if the plant gets bigger, is male, female or switching it up.

Reston Winter Bird CountBy Abby Stocking The Reston Winter Bird Count was held on January 2. Thanks to the 25 volunteers and 3 RA staff who participated in this year’s count. The Winter Bird Count is one of two annual counts that helps Reston Association monitor the success of our community in supporting a variety of wildlife. On this year’s count, there were 51 species of birds observed and over 2,000 individual birds recorded. That is about average for a winter count. The species seen in the greatest abundance were the Canada Goose, American Robin, Northern Cardinal, and Cedar Waxwing. A new species for a Winter Bird Count were a pair of Redheads observed at Bright Pond. Redheads are ducks that are found in northern Virginia in the winter, but are not frequently observed in Reston. A Common Raven was also observed, which is a bird that is becoming increasingly more common in Reston. Volunteers gathered for lunch after the count at Nature House where they were able to share their findings as well as their favorite sightings of the day.
