Great Falls Park - VirginiaGeology at Great Falls, MD  1 SPOT LEFT
Sunday, June 26 (8-11 am)
Leader: Joe Marx
Members $20; nonmembers $28
People in our region find Great Falls both fascinating and perplexing. Arguably our most dramatic landscape feature, its origin and development remain obscure to many. We will take a short and easy walk from the Great Falls Tavern Visitor Center to the falls overlook, a round trip of about a mile. During the walk, we will discuss how the bedrock of the Great Falls area formed in tectonic collisions hundreds of millions of years ago and how the waxing and waning of the continental glacier led to the much more recent creation of the falls. There should even be time to examine the flora and birdlife along our path.

Forest Bathing Walk  FULL - REGISTER FOR WAITLIST ONLINE
Sunday, August 7 (9:30 am-12:30 pm)
Leader: Melanie Choukas-Bradley
Members $28 nonmembers $40
We are happy to offer a Shinrin-yoku or forest bathing walk on a farm in Comus, MD near Sugarloaf Mountain. Numerous studies in Japan, Europe and North America have demonstrated the health benefits of spending quiet time immersed in nature, including lowered levels of the stress hormone cortisol, lowered blood pressure, increased immune system function, and elevated mood (things that ANS members already knew!). We will walk less than a mile at a slow pace and spend quiet time sitting and watching summer wildflowers and nectaring butterflies.  Our leader says this walk is “more about being than IDing.” She has portable forest bathing stools to loan to each participant for the duration of the foray. Melanie welcomes any questions about this new form of nature meditation, which evolved from practices in Japan and Korea: mcb@melaniechoukas-bradley.com.

DamselflyIntroduction to Dragonfly and Damselfly Studies
Thursday, August 11 (7:30-9:30 pm)
Sunday, August 14 (3/4 day field trip)
Leader: Richard Orr
Members $46; nonmembers $64
Lecture only $20/$28
Grab your binoculars and prepare to set your sights not on birds — although “mosquito hawk” is a common moniker — but on those six-legged, aerial acrobats of wetland habitats: the dragonflies and damselflies. On Thursday evening, local entomologist and dragonfly expert Richard Orr will use slides and videos to discuss identification, biology, and behavior of the more common species of Odonates in our area. Our field trip to the Patuxent Research Refuge (North Tract) near Bowie, MD, where our leader has conducted dragonfly studies, will give us a chance to test our identification skills.

Bugs 101
Saturday, August 20 (8:30-11 am)
Leader: Cliff Fairweather
Members $24; nonmembers $34
All true bugs are insects, but not all insects are truly bugs. Confused?  In this field trip for beginning bug-huggers, a naturalist will try to clear up such confusion. Using the McKee-Beshers WMA near Poolesville as our outdoor classroom, we’ll learn to distinguish insects from related arthropods, and look for the identifying characteristics of major insect groups. Our leader will also talk about adaptations, life histories and ecology. Field conditions will include sunny, open areas with tall vegetation.

Introduction to the Natural History and ID of Shorebirds: Part 2BairdsSandpiper
Thursday, August 25 (7:30-9:30 pm)
Saturday, August 27 (full-day field trip)
Leaders: Cyndie Loeper and John Bjerke
Members $48; nonmembers $68
Lecture only $20/$28
Shorebirds are among the most spectacular migrants of the avian world.  Many species breed as far north as the Arctic tundra and winter as far south as Patagonia.  In this advanced session of our annual beginner’s class in late-May or mid-July, our leaders will review the natural histories of shorebirds and offer ID pointers in the classroom part of the workshop.  On the field trip to Delaware’s Bombay Hook, we’ll encounter the more difficult plumages of this time of year, including juveniles.  Our late August date will give us chances for rarities, such as Baird’s Sandpiper, and “grasspipers”, such as American Golden Plover and Buff-breasted Sandpiper.  Although the IDs can be more challenging in late summer, beginners who wish to experience the great diversity of species in southbound migration are welcome to sign up.

Crickets Count! Citizen Science Activity
Friday, August 26 (after dark)
Be a part of the third annual DC/Baltimore Cricket Crawl. Participants will learn the songs of eight species of crickets and katydids, then spend a few minutes to listen for their songs and send in their observations.

Our leader is a Master Naturalist Volunteer with a particular passion for these flying mammals. 

Sharp-shinned Hawk flyingOn the Move at Cape May
Monday, September 19 (9 am) to
Tuesday, September 20 (4 pm)
Leader: Mark Garland
Members $100; nonmembers $140
Cape May, at New Jersey’s southern tip, is known around the world as a great concentration point for southbound migrants. Staggering numbers of birds pass through Cape May when the winds come from the northwest after an autumn cold front. A great mix of habitats means there’s always lots to see here, even when the winds don’t bring the big migratory push. Late September is a peak time for migrating falcons, accipiters, warblers, and monarch butterflies. We plan to visit Cape May Point State Park, the Cape May Migratory Bird Refuge, Higbee Beach Wildlife Management Area, and other natural areas around Cape May. Overnight options include a variety of motels, hotels, B&Bs, and campgrounds in or near Cape May. 

Georgetown Geology Loop Hike
Saturday, September 24 (9 am-1 pm)
Leader: Joe Marx
Members $24; nonmembers $34
The Georgetown section of Washington, DC sits squarely on a mass of ancient granite, surrounded by various other types and ages of rock. Our hike will be about 5 miles long, through wooded parkland and along city streets. The terrain is easy to moderate, with hills being the biggest challenge. During our hike, we will visit the Coastal Plain, three canyons, the Piedmont upland, and a major fault zone. Not bad for a walk around town. (Note: this hike will move at a faster pace than our usual naturalists’ shuffle.)

Fall Botany at Gunpowder Falls State Park
Sunday, September 25 (10 am-2 pm)
Leader: Dwight Johnson
Members $24; nonmembers $34
Our leader describes the Hereford Area of Gunpowder Falls SP in Central Baltimore County as “the best walk in the Maryland piedmont.” Join him on this 2-mile walk through rich upland and bottomland woods where we’ll make frequent stops to ID and admire trees and shrubs, ferns, fall fruits, and late-blooming wildflowers.  

OCTOBER 

PurpleGerardiaLate Season Wildflowers
Saturday, October 1 (8:30 am-Noon)
Leader: Sujata Roy
Members $24; nonmembers $34
We’re returning to the wetlands of Huntley Meadows Park, Alexandria, VA, to search for the last blooms of the season in the rich marsh habitats there. Plants will be our primary focus, we’ll also keep our eyes and ears open for wildlife, including still-active turtles, frogs, butterflies, and other wildlife. Flat walking conditions predominate, but forest trails may be muddy.

Window into the World of Fungi|
Thursday, October 6 (7-9:30 pm)
Leader: Tovi Lehmann
Free, but registration required.
Rooted, yet not plants, heterotrophs, but not animals (growing in fairy rings, yet not even fairies), fungi are members of another kingdom. Mostly hidden under the surface, fungi have evolved their own solutions to life’s persistent problems. Gaining the recognition for their pivotal role in shaping the living world, they now reshape fundamental perceptions of biologists. In this lecture at our Woodend Sanctuary, we will explore the natural history and ecology of our local fungal neighbors, rather than focus on the edibility of particular species of mushrooms.

Fall Flora Fridays

Our Senior Naturalist leads these broad-based nature explorations of nearby parks rich in natural history. We’ll walk up to 3 miles, on possibly muddy surfaces, as we enjoy changing fall colors, late season blooms, migrant birds and butterflies, and all manner of wildlife. Battle Creek Cypress Swamp Sanctuary in Calvert County is considered the northwestern-most bald cypress swamp in the US. Here, piney woods and farm fields surround the 100-acre swamp, accessed by a boardwalk trail. Kenilworth Aquatic Gardens Park, on the banks of the Anacostia River, harbors a variety of plant and animal life in its swamp, marsh and woodland habitats within sight of urban sprawl. An exploration of the Coastal plain woods and wetlands of Mason Neck National Wildlife Refuge near Woodbridge will conclude our series. 

Introduction to Tree Identification
Friday, October 14 (10 am-3 pm)
Leader: Stephanie Mason
Members $30; nonmembers $42
Fall is a great time to learn to identify our local trees and shrubs. With brilliant leaves highlighting the twigs, new buds already formed, and many fruits hanging on, there are lots of distinguishing features that help sort out the various species. This program at our Woodend Sanctuary will begin indoors with a look at some techniques of tree identification, coupled with practice using a simple key. We’ll then move outdoors to use our new skills to identify many of the trees growing on the grounds. Both beginners and those who want to brush up on their ID skills are welcome. 

Fall on the Appalachian Trail
Sunday, October 16 (full-day hike)
Leader: Stephanie Mason
Members $34; nonmembers $46
One of the best ways to explore the seasonal richness of our region is to take a trek along the Appalachian Trail. We’ll hike about 6 miles in the fall woods on Maryland’s South Mountain, covering the stretch from Gath land State Park, the former estate of a Civil War correspondent, to Fox Gap, an area of heavy fighting in the Battle of South Mountain. We’ll stop to enjoy fall plant displays, as well as animal activity, but we will keep a pace necessary to cover the distance stated. Our hike should be considered moderately strenuous to strenuous, with both uphill and downhill hiking over rocky and uneven terrain.  

ChickenOfTheWoods2Fall Fungus Walk
Saturday, October 22 (9 am-12:30 pm)
Leader: Tovi Lehmann
Members $24; nonmembers $34
Fall is a great time to get introduced to the most common families of fungi in our area and find out more about their natural history and many ecological functions. We’ll visit Brookside Park in Montgomery County, where the natural surface trails will include some uphill and downhill walking. Note: the focus of our field trip is fungi’s important and under-appreciated role in forest ecology, not the edibility of particular species of mushrooms. 

The Natural and Cultural History of the Ag Reserve
Wednesday, October 26 (10 am-4 pm)
Leaders: Melanie Choukas-Bradley & Stephanie Mason
Members $30; nonmembers $42
Thirty-four years ago, with regional farmland rapidly diminishing, Montgomery County had the foresight to set aside more than 90,000 acres of farms and open space in the western and northern third of the county as an “Agricultural Reserve.” Come explore this scenic, biologically diverse area and learn how it contributes to clean air and water, the availability of fresh local produce, and the overall quality of life for residents of the metro area. Our trip will visit a working CSA farm, a fall produce and pumpkin stand, an historical site, and perhaps an artist’s studio, time permitting, to experience the rich diversity of plants and wildlife (and human livelihoods) that thrive in the Reserve’s fields, meadows, wetlands, and rocky woodlands. We’ll begin and end the tour in some of the beautiful parkland along its borders: Seneca Creek State Park and Dickerson Conservation Park, site of an American sycamore, officially the largest known tree in MD. 

Late Fall at Cape May  FULL - REGISTER FOR WAITLIST ONLINENorthernGannet
Saturday, October 29 (8 am) – Sunday, October 30 (5 pm)
Leader: Mark Garland
Members $100; nonmembers $140
Cape May is one of the premier spots in North America to see concentrations of southbound birds during the fall migration. October’s end typically brings the year’s largest concentrations of coastal waterbirds, including scoters, cormorants, and gannets, along with temperate songbird migrants -- those species whose migrations stop before reaching the tropics. When the weather conditions are right in late fall, there can be many thousands of sparrows, blackbirds, American Robins, Eastern Bluebirds, Gray Catbirds, kinglets, and others. This is also a time when rare birds show up in Cape May. Some owls are migrating too, and we may have a chance to visit researchers working at night to band them.  

A Year at Boundary Bridge

Section D: October 29
Leader: Melanie Choukas-Bradley
Each walk members $30; nonmembers $42
Join the author of the award-winning book, A Year in Rock Creek Park—the Wild, Wooded Heart of Washington, DC, for our 10th year of hikes in one of D.C.'s most beautiful wild areas. Celebrating the National Park Service's Centennial during 2016, we'll start at Boundary Bridge and follow the same 2.5 mile loop trail each season, admiring and IDing the rich plant life along a scenic stretch of Rock Creek. We'll also see and hear many species of birds, butterflies, and amphibians. Melanie will introduce the Japanese concept of "forest bathing" or shinrin-yoku, a mindful and sensory form of nature meditation with proven health benefits, during a portion of each of her 2016 walks. On our winter walk, an ideal time to admire the Park's topography, we'll look and listen for winter flocks, identify many species of woody plants, and find the first skunk cabbages in bloom. In April, we'll witness the spring magic of Rock Creek's myriad wildflowers. As summer arrives in the Park, we'll hope for a glimpse of a kingfisher as we look for ferns and early seasonal wildflowers such as enchanter's nightshade. Autumn is glorious in Rock Creek Park, and we'll conclude our series with a walk through colorful oaks, maples, and ashes, searching for the flowers of an early witch hazel in bloom. Our hike will be on trails with moderate uphill and downhill walking. An ANS/Rock Creek Conservancy Partnership.

Raptors on the Move at Waggoner’s Gap
Saturday, October 29 (3/4 day field trip)
Leaders: Liam McGranaghan and Laura McGranaghan
Members $30; nonmembers $42
Fall brings thousands of migrating raptors—hawks, falcons, eagles, and their allies—to the Appalachian ridges and Atlantic coast. Our field trip goes to one of the premier hawk-watching sites in the area: Pennsylvania’s Waggoner’s Gap, about a 2.5-hour drive from DC. Our experienced leaders, known for their raptor expertise, will help you develop your own ID skills for these birds-on-the-move. Getting to the hawk watch lookout requires walking up a short, but rocky, trail to an outcropping of perched boulders.

With trees ablaze in fall colors and their fruits hanging high, we’ll learn the identifying characteristics visible through binoculars of the most common species of trees and shrubs along the C&O Canal towpath upstream of Carderock. 

Geology of the Gettysburg Battlefield
Sunday, October 30 (10 am-3pm)
Leader: Joe Marx
Members $30; nonmembers $42
Although geology in 1863 was an immature science and military geology had not yet been invented, the terrain of southern Pennsylvania directly influenced the strategies and actions of the Union and Confederate armies in their climactic clash at Gettysburg. We will tour the battlefield by car and on foot, visiting a number of sites that reveal the geologic processes and materials that created the landscape. In addition, we will discuss several of the regional topographic features that funneled the two armies to their meeting place. We will do several short and relatively easy circuit hikes, totaling a couple of miles in both open and wooded terrain. The ground will vary from dusty or muddy to rocky, and from level to relatively steep. Note: The pace on our geology hikes is faster than the usual naturalists’ shuffle.

TulipTreeInFallBotanical Gems in Montgomery County: Black Hill Regional Park
Sunday, November 6 (9 am-12:30 pm)
Leader: Carole Bergmann
Members $24; nonmembers $34
Designated one of Montgomery Parks Best Natural Areas, Black Hill Regional Park near Boyds offers plant enthusiasts a number of special habitats to explore. The county’s forest ecologist will lead us on a loop hike (between 2-3 miles) to visit some of these, such as: lakeside; early succession meadows; high-quality, chestnut oak-dominated forests; mixed oak forests; and tulip tree-dominated forests. We’ll ID plants along the way, focusing on their seasonal aspects and ecological niches. 

Knock, Knock
Saturday, November 19 (9-11:30 am)
Leaders: Pam and Chris Oves
Free, but registration required.
On this approximately 4-mile roundtrip bird walk along the Canal’s towpath at Riley’s Lock, we’ll work to see or at least hear all 7 species of woodpeckers (a grand-slam!) that frequent our woods this time of year. Our walk is aimed at beginning birders, but all are welcome.
