One of the things most loved about birds is their wild array of plumage colors and patterns. Where does all that color come from? In this presentation, you’ll learn how pigments and microscopic structures in feathers create the kaleidoscope of beauty we find in the avian world. Topics covered include iridescence, molting and feather wear, the evolution of feather color, and the functions of feather colors.  Audubon Society of Northern Virginia presents.

Ivan Phillipsen is a professional naturalist guide with a background in scientific research. Amphibians and reptiles were his first obsession as a kid. He eventually earned a PhD in Zoology, working in the field of conservation genetics. Ivan’s love of nature has expanded to include plants, fungi, and all animals, including birds. Birds have become his greatest passion. He’s an avid birder, hosts The Science of Birds podcast, and co-owns a birding ecotour company.

Northrop Grumman Awards Community Service Grant to FMN

FMN Lori Scheibe, a Northrop Grumman employee, applied for and received a $500 Community Service Grant to benefit our chapter. Lori says, “Most people who are familiar with Northrop Grumman, think of us as a technology company supporting space, aeronautics, cyber or defense. Over the last few years, one of the things that has inspired me about working at Northrop Grumman is our commitment to environmental sustainability including minimizing our operational footprint and utilizing technology for conservation. Our conservation projects include tracking the quality of coastal waters and forests; monitoring reef health metrics and environmental conditions to support oyster restoration in the Chesapeake Bay; developing sensor data technology for sea turtle conservation on the Florida coastline and my favorite, mapping ice formations in the Arctic for tracking polar bear migration patterns.”

“Northrop Grumman encourages volunteering in four areas: STEM education, support for military/veterans, health and human services and the environment. The FMN mission directly aligns to the environment as well as STEM education. I think volunteering at Science Fairs is a double win.”

Giving back to the community is interwoven into the culture at Northrop Grumman. They believe their employees’ support, dedication and passion help strengthen the partnerships they build in the communities where they work and live. Volunteerism is encouraged as a way to network, team build and develop leadership skills while making a difference. Northrop Grumman provides Community Service Grants in recognition of their employees’ volunteer efforts, whether at a Northrop Grumman volunteer event or when volunteering on their own.

Thank you, Lori! We will certainly use this donation to benefit the environment.

Rare Plant Reintroduction and Restoration, recorded webinar

Watch the presentation now on Vimeo.

On May 12th, Matt Bright of Earth Sangha made a presentation on Rare Plant Reintroduction and Restoration for the Potowmack Chapter of the Virginia Native Plant Society.

Matt reviews how the Earth Sangha and Fairfax County Park Authority have collaborated on reestablishment of several state-rare native plant species, some of the challenges that work has entailed, and why home gardeners may be better served — and better serve our local environment — by focusing on more common plants instead

Audubon Society of Northern Virginia and the Virginia Society of Ornithology are proud to present an author talk with New York Times Bestselling Author, Scott Weidensaul!

His recent book, A World on the Wing: The Global Odyssey of Migratory Birds, has captivated birders and non-birders alike with stories of astounding discoveries about the navigational and physiological feats that enable migratory birds to cross immense oceans or fly above the highest mountains, go weeks without sleep or remain in unbroken flight for months at a stretch.

For this lecture, author and researcher Scott Weidensaul takes you around the globe — with researchers in the lab probing the limits of what migrating birds can do, to the shores of the Yellow Sea in China, the remote mountains of northeastern India where tribal villages saved the greatest gathering of falcons on the planet, and the Mediterranean, where activists and police are battling bird poachers — to learn how people are fighting to understand and save the world’s great bird migrations.

How to Invite Hummingbirds to Your Backyard

Article and photos by FMN Barbara Saffir

THEY’RE BAAAACCCCCKKK!  Flying fairies — ruby-throated hummingbirds — returned to Virginia in April so now it’s time to invite some to your house or apartment.  It’s easy and cheap.  Just serve up some irresistible food and an inviting home.  That means a clean hummer feeder, native plants, and nearby trees for them to eat, nest, and snuggle in.  A water source is a huge plus for all birds and critters, especially to help them survive summer’s searing heat.  And it’s also paramount to avoid insecticides in your yard since bugs are the main course and high-octane fuel for these feisty, flying jewels that can beat their wings about 53 times each second, according to Cornell’s respected “All About Birds” website.  Ruby-throats are the only hummers that nest east of the Mississippi.

First the flowers.  Even if you can’t plant salvia, cardinal flower, bee balm, coral honeysuckle, trumpet vine, or other hummer-magnets in time, or if you live in an apartment with a pint-sized balcony, you can still buy them in containers.  It’s best to place them near your hummingbird feeders so they can slurp some sugar water for desert after gobbling down their bug buffet.  Cornell says they especially love the bugs that humans sometimes hate, including disease-carrying mosquitoes, gnats, fruit flies, small bees, and spiders.  And your local big box store is NOT the ideal place to buy hummer plants. Native plant nurseries appear to be the best sources for hummer-preferred flowers.  When you go shopping, if you can, chose the plants with butterflies or hummers already feeding from them. And gobs of other wildflowers and flowering trees seduce hummingbirds, not just the ones you typically hear about.  Virginia Tech offers some suggestions below.

Second, the feeders.  All you need is a $4 hummingbird feeder (see below) and some plain white

granulated sugar.  But NEVER hang any hummingbird feeders unless you’re willing to clean them every couple of days in the heat because dirty ones can form mold, fungus, bacteria, and fermentation, which can hurt or kill your hummers.  The National Wildlife Federation says you need to refill the nectar “as often as every two days when summer temperatures remain above 90 degrees F.  Rinse the feeder thoroughly—without soap—before refilling. Clean it once a month with a very mild, diluted bleach solution.”  It also helps to hang the feeders from a ($4 and up) ant moat to prevent ants from monopolizing the nectar.

Don’t add anything to Audubon’s standard nectar recipe: “The best (and least expensive) solution for your feeder is a 1:4 solution of refined white sugar to tap water. That’s ¼ cup of sugar in 1 cup of water. Bring the solution to a boil, then let it cool before filling the feeder.”
Hummers love water but ordinary bird baths are too big for little ruby-throats, which only reach 3.7 inches long and weigh 0.1-0.2 ounces, roughly the weight of a penny.  Instead, they love to take showers in misting sprinklers and they sometimes flock to bubbling fountains, says “The Spruce” website.
Male hummers (only adult males have full red throats and they only appear red in the sun due to the feather structure) start to return to Florida and Central America by August. But keep your feeders up through October because some young males and females are hungry stragglers. And when autumn rolls around, offer orange jewelweed wildflowers to your hummers.  If you can’t wrangle up a supply, just stroll along the W&OD Trail by Hunter Mill Road or any other trail or garden with lush jewelweed and if you listen and watch carefully, I almost guarantee that you can find some happy hummingbirds.
