Fall 12 Volume Seventeen

Let’s put this on the table from the start: Coyotes are smart. Look up “coyote” online or in a book and you will find a variety of words to describe it: clever, intelligent, socially complex, unique, amazing, successful, adaptable.

Even the coyote’s human detractors begrudgingly recognize this animal’s intelligence. In the legends of many Native Americans, especially southwestern tribes, the coyote is often portrayed as a trickster or culture hero. Their intelligence adds an air of mystery, and is mainly responsible for coyotes being one of the most successful and widespread of North American mammals.

Keep it down out there!No trait of the coyote lends greater credence to its intelligence than its frequent vocalizations. The use of a variety of yips, barks and howls conveys information to other coyotes. Group howls can be territorial, warning other transient coyotes that they are not welcome. The group will also howl to call the family unit back together after individual hunting. Short barks are used to communicate danger, while yips welcome family members back from the hunt.

Wile E. in RestonBy Ken Rosenthal

But don’t be fooled. Just because you haven’t heard a coyote in Reston doesn’t mean that they’re not here. Coyotes in the eastern states are much less vocal than western coyotes. This may be due to the higher density of people and domestic dogs. The best times of year to hear coyotes are during their breeding season in January and February or when their young are moving about and learning vocalizations from their parents in the summer.

Wile E. in Reston continued from page 1

New NeighborsOriginally, coyotes were thought to be a species of open grasslands and prairie, and were first called “Prairie Wolf.” Their diet is varied and uncomplicated. If it is small enough, they will eat it-rodents, rabbits, birds, reptiles, insects, fruit, nuts, carrion, and garbage as a small sample. With the extirpation of the gray wolf, their chief competitor and predator, coyote populations have flourished. An easy appetite, no natural predators, little to no competition from other predators, and the adaptability to live in close proximity to humans have allowed coyotes to thrive. They have expanded into forest habitats and lands east of the Mississippi River in the absence of wolves.

Despite more than 200 years of hunting and trapping, coyotes continue to survive and expand their range. They are now found from Alaska to Central America, across much of Canada, and throughout the lower 48 states. Northern Virginia is no exception. Confirmed coyotes sighting in Reston date back more than ten years and cover all areas.

What does a coyote look like?At first glance, eastern coyotes can have a German Shepherd-like appearance. They tend to have brownish-gray fur, long legs and a black tipped tail, which they carry low to the ground. Most adult coyotes weigh between 35 and 60 pounds, which is much larger than our common Red Fox, which sports a white tipped tail, often carried high when walking.

Should I be concerned?Like any large predator, coyotes should be treated with caution. But living in fear is not the answer. Coyotes tend to be nocturnal, non-confrontational and shy, slinking away as soon as they detect a human presence. You are more likely to be harmed by a traffic accident, lightning strike or domestic dog than a coyote.

The risk of a negative encounter with a coyote increases when coyotes become too accustomed to people. There are several safeguards you can take to prevent negative encounters. Never feed coyotes, and do not feed your pets outdoors. Keep small pets such as cats and rabbits inside. Keep your dog on a leash during walks. Secure your trash cans with tight fitting lids. If a coyote approaches you, yell or make loud noises to scare it off. You can also throw rocks or sticks near the coyote. This “hazing” will benefit coyotes by keeping them wary of humans.

There is good news that comes with having coyotes in Reston. They can help curb the growth of certain populations of wildlife often considered a nuisance for people such as rodents, Canada geese and deer. While mice and rats are staples in a coyote diet, Goose Eggs are quite a delicacy as well as an occasional full goose dinner and even though a large, strong deer may be too much to take down, a small, sick or injured deer makes a great coyote meal.

Observing coyotes can be fun and rewarding. Understanding how to coexist with them safely can ensure that these experiences will be positive.

Wildlife Count ResultsBy Abby Stocking, Katie Shaw and Kevin Munroe

Summer Bird Count: June 2Over 20 volunteers participated in the count, breaking into four groups to tally the number of species and individual birds seen and heard in Reston’s natural areas. The information collected gives a snapshot of how well our natural areas support wildlife.

This year’s count was quite impressive. There were 64 species of birds identified and over 1,200 individual birds counted. Since the count started in 1997, the only year with a higher number of species was 2007, with a total of 68. Several birds were seen for the first time on a summer count, including Osprey, Blue-winged Warbler and American Redstart. The birds seen in the highest numbers were the Northern Cardinal, American Robin and Common Grackle.

Butterfly Count: July 7Temperatures weren’t the only records being broken this summer. We also broke the Reston record for the most butterflies tallied on a count day. 17 people counted 435 butterflies of 27 species, just one species short of the record last set in 1999.

Counters gained a newfound appreciation of skippers, since 255 of our butterflies were in this family. The Sachem Skipper was the most

prevalent species with 181 counted. The next most numerous species included the

Cabbage White, Eastern Tiger Swallowtail and Eastern-tailed Blue. Special finds were a Meadow Fritillary at the Fox Mill Meadow, a Northern Cloudywing in North Reston, a Viceroy at Lake Audubon, and Tawny-edge Skippers

found in the Sunrise Valley Wetlands. Our data was submitted to the North

American Butterfly Association for inclusion in it’s annual report.

Dragonfly Count: July 14For a count that almost got rained out, 16 species made it a fine success. 14 counters participated, adding the last species, a Least Clubtail, to the results in the Glade Stream Valley near Twin Branches. It was great to see this uncommon stream species in exactly the same spot as last year. Two Black-shouldered Spinylegs along Buttermilk Creek Nature Trail were also counted. Although not uncommon in Northern Virginia, it was only the second time the species had been recorded in Reston.

Many thanks to all who participated in the counts. The next count will be the Winter Bird Count on Saturday, January 5.

THE OTHER ACORN EATERSBy Earl the Squirrel with help from Abby Stocking

What animals come to mind when you think of acorns? Hopefully you think of squirrels, and maybe chipmunks, too. While we certainly eat plenty of acorns, there is another critter that also feeds on these delicious nuts. Acorn weevils are small insects that use acorns as food, nurseries and homes.

There are many different types of acorn weevils. Most weevils are about ½ inch long. Many acorn weevils have long snouts that can be about the same length as their bodies. In the summer when acorns are growing on trees, weevils use sharp jaws at the end of their snouts to drill through the acorn shell and eat the nut inside.

The acorn weevils are not just eating the acorns. Females dig a tunnel into the center of the acorn and lay an egg inside. The acorn helps protect the egg. The eggs hatch after a few days. Legless larvae grow inside the acorn for a few weeks. The larvae look like white worms, and are the young form of the weevil. When the larvae are full size, they will chew their way out of the acorn, leaving a small hole in the shell. By this time, the acorn has fallen to the ground. The larvae burrow underground where they will live for one to two years. When summer comes, adult acorn weevils will come out of the ground and start the life cycle again.

We squirrels prefer to eat acorns without weevils. If you look on the ground in late fall, you may find

some acorns we’ve left behind. If they have small holes in them, you’ll

know why we didn’t eat it. It was probably a home to

an acorn weevil.

Kid’s Corner

Find an Acorn WeevilFollow these steps to see if you can find an acorn weevil inside an acorn.

ACORN MAZEHelp the weevil get to the center of the acorn.

1. In early fall, gather a few acorns that have fallen from an oak tree.

2. Put the acorns in a bucket full of water.

3. If the acorns float on top of the water, then they are most likely home to some kind of insect.

4. With an adult’s help, use a nutcracker to open the shell of the acorn. Try not to crush the nut inside. Look for a small, wormy creature inside the nut.

5. If it is whitish and shaped like the letter “C”, it is most likely an acorn weevil. If it is green like a caterpillar, it is most likely an acorn moth larva.

Native Spotlight: RED CHOKEBERRY & BLACK CHOKEBERRY(Photinia pyrifolia & Photinia melanocarpa)

By Sharon GurtzNative to eastern North America, chokeberries are deciduous shrubs belonging to the rose family. They are multi-stemmed, medium to large shrubs with an oval shape. Red varieties grow to 6 -10 feet tall, and the black matures at 3 - 7 feet. Red ‘Brilliantissima’ and black ‘Autumn Magic’ are common cultivars of this native that have excellent fruit production and fall foliage. Chokeberries prefer sun to part-sun and wet or dry soils that are slightly acidic. Planting in full sun results in best flower and berry production.

ColorfulFrom spring into winter you can enjoy the seasonal colors of these plants. Clusters of fragrant white five-petaled flowers appear in the spring from April to May. The dark green, glossy leaves of summer give your garden color in the fall as they turn orange to red. Bright red or black pear-shaped berries are prevalent in fall and persist into winter. Although the berries are edible, they are very tart and bitter. The common name is said to have originated from the “choking” reflex of people attempting to eat them.

Wildlife ValueWhile not a favorite of most backyard birds, the berries are eaten by Eastern Bluebirds, Brown Thrashers, American Robins and Cedar Waxwings. Chokeberry plants are sometimes used as a larval food by underwing moths and a source of nectar for insects. They also provide protective cover for wildlife.

Chokeberries can be used as a border and pruned as a hedge. They can form sizable colonies and are excellent for use in your natural landscape instead of invasive exotic species such as Winged Burning Bush or Bush Honeysuckles, which are banned from new plantings in Reston. Chokeberries are seldom severely damaged by deer.

Get Nuts For Clean WaterHow to Help:

• Collect acorns in your yard or other open area where the acorns will not be able to grow.

• Please do not collect at the nature center or any natural area in Reston.

• Separate the acorns by species and place them into breathable bags

(no plastic bags). • Label each bag with the kind of nuts that are inside.• Store in a cool dry place then drop

them off at the nature center.

When: Nut drop offs are accepted September 15 – October 21.

Where: Information and collection bags can be picked up at the Walker Nature Center. Please deposit bagged and identified acorns in the container on the side porch at Nature House. Contact: Sharon Gurtz, [email protected], 703-435-6514.

This fall, you can help to restore native forests and protect streams throughout the Potomac River region, one acorn at a time. When those acorns fall from the trees in your yard or you see them in an open space, don’t rake them away with the yard waste. Consider getting involved in this fun activity that can be enjoyed by all and help with reforestation.

Citizens throughout the Potomac River watershed are invited to take part in a native seed collection effort. Collected seeds are donated to state tree nurseries, where they are nurtured and transplanted for use in streamside and riverside reforestation.

Growing Native is coordinated by Potomac Conservancy on behalf of the Potomac Watershed Partnership. For additional information about the program, detailed instructions (including desirable seeds),and seed identification materials, visit www.growingnative.org.
