In 2007, Andrea Vojtko of Arlington Village compiled a bird list that helped Joanne Wagner, a member of the Environmental Resources Committee at that time, obtain recognition of the Arlington Village ravine as a Certified Wildlife Habitat by the National Wildlife Federation.  Andrea has generously shared her wonderful list with us.  We hope that it might provide a stimulus for the formation of a birding group in the village that would monitor the birds that come and go and stay in Arlington Village.  A prime purpose of our ravine restoration project is to restore a native habitat in the ravine that supports our native birds.  Regular monitoring of the birds of Arlington Village would provide an important measure of our progress.  Please respond to this post if you are interested in being a part of an Arlington Village birding group, and look for an announcement of a future organizational meeting.

 Andrea explains more about her list:  These are birds that I observed at various places in Arlington Village in 2007. I was a longtime birder and am still a member of the Audubon Naturalist Society, Northern Virginia Bird Club, and Friends of Dyke Marsh. Perhaps a new group of birders in Arlington Village can be formed for the next Spring migration to add to this list which I’m sure is incomplete. The more pairs of eyes looking for birds, especially during the migration period, the more likely you are to increase the number on the list.

Notes:

a) Birds were seen nesting in, passing over or through the Arlington Village area, many during the bird migration periods.

b) It is probable that several other species can be added to the list since a number of relatively common birds are missing from the list.  Thus, I anticipate that the list will grow over time.

c) Birds are listed in same order as on Birds of Virginia cards distributed by Virginia Society of Ornithology.

Clang!   Ting!   Over the course of several weeks members of the Environmental Resources Committee dug in the rocky soil.  Over 100 volunteer hours were invested to establish a new planting area near the ravine entrance on South Barton Street.  This new area features several native Virginia plant species—Scarlet beebalm, Orange coneflower, Black-eyed susan, Purple lovegrass, and Smooth blue aster (see below).  These native plant species support a large number of butterflies and other pollinators.

The realization of this project involved several steps.  First of all, the area required “cleaning” because invasives had, as they typically do, taken over the site.   Volunteers pulled out Smartweed (Polyganum persicaria), Lemon balm (Melissa officinalis), and other invasive plants.   After this, volunteers turned over the soil to remove more invasive plants and to prepare the ground for planting.  Earth Sangha, a local nonprofit native plant nursery, provided the plants.  The final steps were planting, mulching, and generous watering.  Volunteers took great satisfaction in completing this project and look forward to enjoying a lovely restored area of the ravine with the rest of the Village.

Future work and plantings in the ravine can always use more hands. Please email ERC Chair, Rodney Olsen, at rfolsen@verizon.net to be added to the list or keep an eye on this blog:

A light mulch will keep winter weeds from germinating, but don’t put down a layer more than two inches thick. Keep mulch away from the base of trees and shrubs. Mulch volcanoes around trees have no horticultural merit and will harbor bark-chewing mice.

Watershed Planning Meeting: Four Mile Run – Upper and Middle Mainstem Wednesday, November 30, 2011. 7:00 – 8:30 PM., Fairlington Community Center, Room 100.  Residents in the upper and middle mainstem of Four Mile Run are invited to join the County and the Center for Watershed Protection on Wednesday, November 30 to learn about the Four Mile Run watershed study, the County’s plans for addressing polluted runoff, and opportunities to reduce pollution in these watersheds.

Arlington Village’s ravine is the beneficiary 50 Christmas ferns. These plants are of a local ecotype and were rescued by Earth Sangha from a site slated for development. Volunteers from the Environmental Resources Committee spent close to 20 hours carefully planting the ferns in their new home – the steep hillside by the S. Edgewood entrance to the ravine.

Christmas ferns are thought to be so named because they are evergreen year-round, one of the few Eastern ferns with this characteristic. A more fanciful suggestion is that the name stems from the pinnae’s resemblance to Santa’s boot or to a Christmas stocking. In addition to increasing the native habitat of the ravine, ferns provide erosion control on the steep bank. Take a look as you walk by.

“We found this little bird shivering out front and not moving on the ground,” wrote Ashley. “I think he is a Golden-crowned kinglet, maybe off the migration path from the storm?  It doesn’t seem like a normal Arlington bird, but I may be wrong.  So my question is should I leave him outside in the cold?  Or should I keep him warm until tomorrow and let him go?”

Ashley received advice from Master Naturalist Jim Hurley who said it was definitely a male Golden-crowned kinglet, a bird that was presently migrating through the area.  He made some suggestions for caring for the bird inside and suggested that Ashley seek more ornithological expertise.  Jim later conveyed advice from another Master Naturalist who offered more tips for care.  Jim also suggested calling the Wildlife Hotline at 703-440-0800 to receive further advice and to obtain the phone number of a licensed bird rehabilitator.

But Ashley was seeing that she could care for the bird herself.  Later that evening, she wrote, “the little kinglet seems to be making a recovery.  He is alert and curious.  And then sleepy again.  We will release him in the morning.  What a mellow neat bird.   He seems to enjoy just hanging out on a stick while I hold it.”

The following morning, Ashley wrote that the “little kinglet was released.  He was up and ready to go after a warm night of snoozing.”  She offered details of the care she had provided the bird:  She had placed him away from her dog and cat in her bedroom, in a “shoebox with holes in the lid.”  The shoebox was lined with a t-shirt for “warmth and softness.”  She placed twigs on the folds of the t-shirt for the kinglet to perch upon.  “He was very unsteady and would just sit with his eyes closed.”  She put a drop of water on the bird’s beak and “he would snap it up.”  She gave him a worm that he “wrestled with” but did not eat.  She checked on him many times to see how he was doing and also because “he was so cute.”  The kinglet later flew around a bit in their bedroom and perched on the ceiling fan.

When Ashley took the bird outside in the morning, she reported, “I opened my hand and he flew straight up to a maple tree, preened a little, cleaned his beak, and hopped around.”  Ashley’s last words to the bird were “Good luck little kinglet!”

Here are two more of Ashley’s photos of the Golden-crowned kinglet:

Application

Drawing by Rodney Olsen

Arlington Village has been awarded 15 trees by the Tree Canopy Fund.  The fund is an Arlington County project, administered by Arlingtonians for a Clean Environment (ACE).  Trees, meant to replenish Arlington County’s diminishing tree canopy, are awarded in a competition involving Arlington County homeowner groups and townhouse associations.  This year the Fund granted trees to 34 applicants.  Arlington Village’s application was a joint project of the Grounds Committee and the Environmental Resources Committee (ERC).  The trees, worth $4,540, are young, good-sized trees that will add their beauty to our village.  They include the following species:  White oak, Scarlet oak, Pin oak, River birch, American beech. American sycamore, Common hackberry, and Black gum.  Planting of the trees will occur this fall.  The cost of planting the trees is covered by the award.

 

 

 

 

 

 

 

The squash bee (Peponapis pruinosa) relies on pumpkins for survival, and seems to have followed pumpkins across the continent. The bee is a specialist forager and will only collect pollen from squash flowers. Females often nest in the ground around the base of pumpkin plants, and males take shelter in flowers overnight. Because of this, it must once have been limited to areas in which pumpkins are native. Yet today the squash bee has expanded its range, adapting to dramatically different climates and environments, and is found as far south as Florida and north as Ontario. These bees can often be found in home gardens, and will even colonize newly created community gardens amid the tall buildings and parking lots of a city, witness to their amazing ability to follow squash plants!

Although squash bees depend on pumpkin plants, it is not a one-way relationship. Squash bees are highly efficient pollinators of pumpkin flowers. Pumpkin flowers open at dawn, a period of the day that can be too dark or too cold for most bees to be active. The squash bee, however, is adapted to fly in these conditions. It is an early riser, and will often be up half an hour before dawn, the perfect time to visit squash flowers. The bees also have widely spaced hairs in their pollen brush (a patch of hairs for carrying pollen), an adaptation to cope with pumpkin flowers’ large pollen grains.

Squash bees are not the only bees that pollinate pumpkins, which is fortunate for those of us living in the few areas these bees haven’t yet reached. There are four other species of Peponapis and a few species in the closely related genus Xenoglossa, which are also squash specialists. None of these are as abundant or widespread as the squash bee, nor as adept at moving into new areas. Bumble bees, including the common eastern (Bombus impatiens) and the two-spotted (Bombus bimaculatus), also are regular visitors, as is the long-horned bee Melissodes bimaculata, which is often seen on pumpkins in gardens of the eastern U.S. In addition, many farmers rent honey bees (Apis mellifera) to pollinate fields of pumpkins. This range of pollinators ensures the sustainability of North American pumpkin crops and our access to the perfect Halloween pumpkin.

With Hurricane Irene approaching, it’s wise to stay indoors. But with rain on the brain, I found this article listing five rainy day activities from the National Wildlife Federation to be a good reminder of the joy we and our children (inner or of the “regular” sort, see above) can find in rain of a safer kind.Plus, here are two bonus rainy day activities from Gene Kelley!

One Ultra-Ex project being led by the Cleveland Botanical Garden involves planting a vacant lot in the Buckeye neighborhood with low-mow fescue, a slow-growing pasture grass, and establishing a vegetative fence. Down the block is one of six learning farms that the botanical garden runs through its Green Corps program. With three acres under cultivation and 60 teenage workers, the urban farms will grow and sell or give away 15,000 pounds of fresh produce this summer, said the program’s director, Geri Unger.

Instead of throwing waste into the garbage, owners would collect it in supplied biodegradable bags, drop them into the digester and turn a hand crank to stir the mixture so the methane rises to the top, where it is burned constantly in the lamp.

“I like ice cream.

Which is why I like working on weeds. Tackling a population of invasive weeds is like eating an ice-cream cone on a hot day.

You have to keep circling the edges to contain the drips, occasionally take a nibble off the main scoop or push it down into the cone–but carefully, because trying to do too much can give you a headache or make a mess.

Going at it systematically, with enjoyment and appreciation for what you’re doing, is your best bet. It’s how I (with a lot of help) killed 100 acres of English ivy*–pull along the edges, slowly so the natives fill in, then circle back to get the resprouts.

And that last bite, so satisfying!”

Like local produce but can’t always make it to a Farmer’s Market?

“South Mountain Veggies—a family-owned sustenance-delivery service—trucks parcels of local and organic produce to homes throughout Washington, DC and its surrounding areas. The medium Family Share box brims with 11–14 servings of seasonal crop ready to munch on, set aside for future cooking ventures, or wear as a hat. The carton’s customizable abilities give household meal planners the option to tailor contents based on familial likes, dislikes, and crippling phobias. South Mountain’s fruit and veggie varieties rotate seasonally, ensuring dinner menus stay healthy and fresh.”

The current Groupon deal entitles one to a box of produce at half off ($18) and lasts through Sunday night.   Delivery to Arlington occurs Thursday nights or Friday mornings.  Groupon
