As we slowly slip into winter from a delightful Fall season, there are still plenty of reasons to get outside with your binoculars. Out in my neck of the woods in western Loudoun, all of the woodpecker species are particularly abundant -- especially the downy, hairy and pileated -- and you can always see the not-so-common red headed woodpecker out at Sky Meadows State Park managed by DCR's Tim Skinner and his staff. And, of course, all of our "year 'rounder" species seem to be everywhere: the chickadees, tufted titmouse, and even the raptors that stick around such as the red tailed, red shouldered and Cooper's hawks. If you're looking for something to see and don't know where to go, you can always ask us at 703-438-6008 or email@example.com.
Also, we want to remind everyone, experienced and beginner alike, that we'll be running our Christmas Bird Count on December 19 this year. If you're a regular, Bob Shipman or one of his sector leaders will be getting in touch with you. But, if you're new to the CBC, give us a call and we'll give you the information you need. The CBC is extremely important in monitoring the state of birds across the continent. It's also an awful lot of fun. So, by all means, come out, have fun and give us a hand.
And, staying on a winter theme, we will also run our annual Winter Waterfowl Count later in January. If that interests you, call us and we'll put you in touch with Larry Cartwright, who is always looking for new volunteers.
Finally, looking way into spring, it seems pretty clear at this point that we will have an opportunity of assisting in a ornithological study to examine stress factors in habitat loss in two identified songbird species being conducted by the biology department at Mary Washington University in conjunction with the Fairfax County Park Authority. Specifically, we at ASNV will be looking for birders who can dedicate several hours a week to conduct a breeding survey which in turn will lead to netting, banding, and blood sampling. This is a wonderful opportunity to really expand your knowledge of birds and bird behavior and if this is something you would like to get involved in, give us a call and we'll start to compile a list of those interested. Although the protocols of the project are still being formulated, we will be looking for volunteers who will agree to participate in a regular team effort over a period of several months.
Stay in touch, Bruce
Time to Sign Up for our Annual Manassas-Bull Run Christmas Bird Count!
Our annual Manassas-Bull Run Christmas Bird Countwill be on Sunday, December 19. Our count circle is around Centreville and includes Manassas Battlefield, parts of Bull Run Regional Park, undeveloped areas south of Dulles Airport, and many stream valley parks and undeveloped locations from Clifton to west Fairfax City. As in the past, well be offering a hot lunch to participants.
We have had good turnouts the past couple of years, but we still need new volunteers. Those of you who participated last year will be contacted by your sector leader in the near future to ask about this year. If you dont hear from your sector leader, or if you would like to be in a different sector, please contact the ASNV office.
Also, this year, we will be offering an opportunity for feeder watchers. If you or someone you know lives within the count circle and cannot go out on the count, he or she can sit inside and count the birds that come to a feeder on count day as an alternate way to participate. If you are new to CBCs and want to volunteer, contact the ASNV office at firstname.lastname@example.org or 703-438-6008.
More information will be provided in next months newsletter.
ASNV's Nature Afternoon: An Audubon Update on the Impact of the Gulf Oil Spill
The Gulf oil spill, the largest environmental catastrophe in U.S. history, has unprecedented impacts for the people and wildlife of the Gulf region. Although the oil leak has stopped, the damage it has caused to the Gulf Coasts most vital and diverse habitats has dire implications for both people and wildlife.
Migratory bird species depend on at-risk habitats like those along the Gulf Coast and the Coastal Plain of the Arctic National Wildlife Refuge. Shortly after the spill, National Audubon Society mobilized volunteers who played a significant role in wildlife rescue, clean-up, and monitoring.
Join ASNV at our Nature Afternoon, when Taldi Walter, Assistant Director of Government Relations for the National Audubon Society, will present an update on what Audubon has been doing and continues to do on the ground in the Gulf region and how the Gulf spill provides a cautionary tale for how our country approaches energy development.
When: Sunday, December 12, 3-5 p.m.
Where: 11100 Wildlife Center Drive, Reston
Directions: From Sunset Hills Road, turn into Lake Fairfax Business Center (Sunset Hills between Wiehle Avenue and Hunter Mill Road). Follow Business Center Drive to the end and turn left. Turn right into the National Wildlife Federation.
Insects in Winter
Cliff Fairweather, ASNV Naturalist
As fall grades into winter, insects disappear from the scene. Or do they? They are still out there, but mostly hidden from view or in forms we dont readily recognize. A few, such as monarch butterflies, migrate to warmer regions, but most remain, usually as eggs, larvae, pupae or, in a few cases, adults. Those that remain through the winter need strategies to withstand freezing temperatures.
Some insects can supercool a process in which they go through physiological changes that inhibit ice formation within their bodies. These changes include reducing the amount of water in their bodies and eliminating body wastes around which ice crystals can form. Supercooled insects can withstand temperatures well below freezing without cell-damaging ice crystals forming. If they are disturbed while in a supercooled state, however, they will flash freeze and die. Consequently, supercooled insects try to find secluded and secure places in which to spend the winter.
Other insects take a different approach, called freeze tolerance. They actually allow ice to form inside their bodies, but in a controlled way that confines that ice to spaces outside the cells. This extracellular ice draws water from inside the cells, reducing their vulnerability to internal ice crystal formation. There is a limit to how much an insect can reduce water in its cells without causing fatal cell dehydration.
Some insects employ both supercooling and freeze tolerance and many insects also produce natural antifreeze to further retard ice formation. A few insects, such as winter stoneflies, use antifreeze to remain active in the winter. Watch for these small, slender, dark insects on rocks, bark or snow near streams. A variety of aquatic insects remain active underwater during winter. In fact, the highest diversity of these insects in our streams occurs in winter; most of these are larvae that will emerge as terrestrial adults in the spring and summer.
Whatever strategy they use for winter survival, insects and other overwintering arthropods provide an important part of the diet of many year-round and winter resident birds. Even entirely insectivorous species, such as ruby-crowned kinglets, manage to find enough insects to survive.

The leader will have a scope and waterfowl identification guides. For directions and additional information, click here.
Advocacy Update: Conservation Depends on You
Congress Should Not Choke EPA
The results of the November 2 election cloud prospects for many environmental bills in the next Congress, most Congressional observers predict. With the switch in control of the House of Representatives, from Democratic to Republican in January 2011, changes in the Houses agenda and priorities are anticipated.
Virginias House delegation changed from six Democrats and five Republicans to three Democrats and eight Republicans. All three Northern Virginia incumbents won (results have not yet been certified by the state): Jim Moran (D-8), Frank Wolf (R-10) and Gerry Connolly (D-11).
The current Congress recessed in early October without passing a comprehensive clean energy and climate bill and now there are rumblings that legislators may try to limit the U. S. Environmental Protection Agencys ability to reduce greenhouse gas emissions under the current Clean Air Act. There were several unsuccessful efforts to limit EPA this past summer.
The Senate rejected Senator Lisa Murkowskis bill, S. J. Res. 26, and both Senators Webb and Warner voted against it. In Senate debate on June 10, 2010, Senator Webb said he would support Senator Jay Rockefeller bill, S. 3072, to prevent EPA from acting for two years. You can read Senators Murkowskis and Rockefellers bills online by entering the bill numbers.
The current Clean Air Act is designed to protect human health and welfare. Greenhouse gas emissions are a threat to human health, many experts say. As the planet warms, for example, climate change will worsen health problems like heat-related mortality, diarrheal diseases and diseases associated with exposure to ozone and allergens from the air. Warmer temperatures encourage the formation of ozone, which aggravates asthma.
The Virginia Commission on Climate Change reported that more extreme weather events from climate change could compromise water and food supplies, increase waterborne and food-borne illnesses and increase the incidence of respiratory and cardiovascular conditions.
EPA administers several laws designed to protect the public health. The Obama administration is using the authority under the current Clean Air Act to tighten up on vehicle emission standards. Without a comprehensive law, the Clean Air Act authority is EPAs primary legal tool for controlling greenhouse gas emissions.
Every day the Congress fails to act means continued dependence on imported oil and fossil fuels, little resolution of the threats to our national security posed by imported oil and climate changes, more extreme weather events like hurricanes and droughts and more threats to public infrastructure and health. Inaction on climate change adds costs to government at every level, from increased flooding from sea level rise to damage from more extreme weather events.
The National Audubon Society opposes bills to curb EPAs authority to reduce greenhouse gas emissions and urges you to ask your current and, if you will have a new one in January, your new Congressman and Virginia Senators Mark Warner and Jim Webb to oppose bills that would limit EPAs authority to reduce greenhouse gas emissions that lead to climate change. How to contact Virginias U. S. Senators:
You can also send an e-mail at your senators web site or through Audubons Action Center.

Clean Up the Chesapeake Bay
ASNV President, Bruce Johnson, sent Virginia Governor Bob McDonnell these comments on the state's watershed implementation plan:
On behalf of the more than 4,000 members of the Audubon Society of Northern Virginia, we are providing comments on Virginias draft Watershed Implementation Plan, part of the U. S. Environmental Protection Agencys total maximum daily load (TMDL) effort to clean up the Chesapeake Bay, a treasured Virginia resource. We appreciate this opportunity.
The mission of the National Audubon Society is to conserve and restore natural ecosystems, focusing on birds, other wildlife and their habitats for the benefit of humanity and the earth's biological diversity. The Chesapeake Bay ecosystem is a valued natural resource and important to the Commonwealths economy. It is an outdoor laboratory for hundreds students, scientists, researchers and outdoor and nature lovers. Despite twenty-five years of effort, the Bay is still degraded and we must take stronger steps toward a clean Chesapeake Bay and fishable rivers and streams. We need to put real, enforceable steps in place.
Several facts show the urgency of this mission:
We are disappointed in Virginias draft watershed implementation/TMDL plan. We urge you to issue a more specific step-by-step plan that has clear requirements, provides funding and establishes real deadlines with the following provisions:
- 12,103 miles of rivers in Virginia were designated as impaired in 2010, 1,560 more miles than in 2008.
- Eighty percent of Fairfax Countys streams are in fair to poor condition. Many do not meet standards for E. coli and PCBs, for example.
- Stormwater runoff is a major, growing source of pollution and inadequately controlled by local and state laws, regulations and land use policies.
Clean water is a shared responsibility. All of us must act. Polls show that Virginians support cleaning up our waterways and the Chesapeake Bay.
- Requirements, incentives and specific actions to reduce polluted runoff from all sources.
- Explicit strategies for controlling urban/suburban stormwater runoff (e.g. remove phosphorous from homeowner fertilizers, require low-impact development for new construction, limit the flooding and pollution from developed properties).
- Sufficient funding in your proposed budget and a commitment to work with the legislature for sufficient funding.
- Proposed legislation to the General Assembly and proposals to amend regulations so all pollution sources help stop the pollution of our waterways.
We look forward to Virginia improving the Virginia plan.
Focus on the State Legislature
On December 4, the Virginia Conservation Network will host the annual VCN Legislative Workshop at the state capitol in Richmond. Up to 150 conservation leaders and activists attend this annual preview of the coming General Assembly session. It runs 9 a.m. - noon in House Room 3 and Senate Room 3. Exhibitors will have information on current advocacy campaigns and speakers will discuss the top issues in VCN's "common agenda for conservation." State legislators are invited speak. Everyone who attends will get breakfast and a copy of the 2011 Conservation Briefing Book.
If you plan to go, please let Glenda Booth know. The Virginia League of Conservation Voters seeks members of their legislative contact teams for every member of the General Assembly. If you can volunteer, let Glenda know. It is not very time consuming.

Hidden Oaks Nature Center (FCPA) sponsors weekly bird walks along the Accotink Stream Valley.
We meet every Monday morning (weather permitting) at the parking lot on Prosperity Ave. about half way between Routes 50 and 236 (Little River Turnpike). We begin at 7:30 a.m. Dec. through Feb. and 7:00 a.m. the rest of the year. No need to sign up. The walk generally goes for a couple of hours but can vary depending on how "birdy" it is and the weather. If you have any questions please contact the leader Carolyn Williams at 703-273-1961.
Volunteer Need to Coordinate Science Fair
ASNV is looking for a volunteer to coordinate our assistance with the Fairfax County and Prince William County public schools science fairs. ASNV is invited every year to judge the science fairs, and this is an opportunity for ASNV to encourage young scientists in research, conservation, and the environment.
This is not a time consuming volunteer effort but does require:
If you are interested, please contact Kristy Liercke at firstname.lastname@example.org or 703-255-3021. Thanks!
- Finding four judges (there are 2 or 3 people who have done this in the past and will readily volunteer to judge so it will probably be necessary to find another 1 or 2 judges)
- Creating a certificate for the judges to give to the ASNV awardees. A certificate was given in the past but probably needs to be improved.
- Coordinating with the ASNV Board of Directors for some prize to give to students.
- Writing up the names of the winners and judges for the Potomac Flier.
- Coordinating with the ASNV office to communicate with the science fair coordinators.
Are You Interested in Natural History?
