Winter Birding at Black Hill
Section A: Sunday, December 1 (8:30-11 am)
Section B: Saturday, January 4 (8:30-11 am)
Section C: Saturday, February 1 (8:30-11 am)
Section D: Sunday, March 1 (8:30-11 am)
Leader: Mark England
Each walk: members $24; nonmembers $34
Entire series $87/$123
The winter months can be an ideal time to learn more about birds and birding, and Black Hill Regional Park, in upper Montgomery County, is an ideal outdoor classroom for this study. Each walk in our series, intended for beginning to mid-level birders, will visit one or more sites in the Park in a search for waterfowl, sparrows, raptors, and other both resident and overwintering species. The Park’s habitats are varied and include wetlands and Little Seneca Lake, as well as forest and field. Join us for the entire series and observe the seasonal changes in numbers and species, or just sign up for individual walks. REGISTER

Georgetown Geology Loop
Saturday, December 7 (1-5 pm)
Leader: Joe Marx
Members: $26; nonmembers $36
The Georgetown section of Washington, DC sits squarely on a mass of ancient granite, surro8nded by various other types and ages of rock. Our hike will be around 5 miles long, through wooded parkland and along city streets. The terrain varies from 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 an afternoon walk around town. The pace set and distance covered on our geology field trips is faster and farther than our usual “naturalists’ shuffle.” REGISTER

Winter in the Parks
(9 am-1 pm)
A: Saturday, December 7: Jug Bay Natural Area, MD
B: Sunday, January 5: Huntley Meadows, VA
C: Sunday, February 2, Rock Creek Park, DC
Leader: Stephanie Mason
Each walk: members $28; nonmembers $38
Entire Series: $78/$108
Sign up for one or more of these seasonal, broad-based nature explorations of nearby parks rich in natural history. Winter is often called the quiet season, but there is still lots to look and listen for in the natural world despite the cold temperatures. Our Senior Naturalist will lead this series of walks to observe winter wildlife and plants, all the while discussing their strategies for winter survival. We’ll work to cover between 2-3 miles, with some uphill and downhill on walks A and C, in order to counter the likely chilly weather. REGISTER

Winter Waterfowl Prowl
Sunday, December 8 (8 am-12:30 pm)
Leader: Mike Bowen
Members $26; nonmembers $36
Early in the year is the best time to search for and learn to ID overwintering waterfowl in our area. Basing our search at wetlands and waterways relatively close-in to the metro area, we’ll visit sites in or near the District, Northern Virginia, or Montgomery County.  Our exact locations will be determined closer to the date of the field trip, based on our leader’s scouting expeditions. While our focus will be waterfowl, we’ll keep an eye open for all birdlife. All levels of birders welcome. REGISTER

Winter Weeds
Friday, December 13 (10 am-2:30 pm)
Leader: Stephanie Mason
Members $28; nonmembers $38
Not all herbaceous plants disappear in the winter. Many persist as dried stalks and seed clusters, with a beauty to match the season. Join ANS Senior Naturalist Stephanie Mason for an indoor/outdoor introduction to winter weed and wildflower identification at our Woodend Sanctuary. We’ll also investigate seed dispersal strategies and examine plant skeletons for signs of summer insect activity, such as insect galls, chrysalids, cocoons, and egg cases. REGISTER
