There’s been a lot of information in the papers on the Chesapeake Bay Preservation Act  - some of it accurate, some of it not.

The Chesapeake Bay Preservation Act is something we need here in Loudoun and we need it now. Over the coming weeks we’ll be posting more information that you can use.

A great resource available right now is the website for Loudoun’s Clean Streams Coalition, of which Loudoun Wildlife Conservancy is a part.  On this website you’ll find information on what the Act means for Loudoun, a history of the Act in Virginia and how it’s been applied in other counties like Fairfax, links to additional resources on streams and buffers, and more.

Additionally, members of our Board of Supervisors and County staff are out and about doing community sessions to hear citizen concerns, debunk myths, and answer citizen questions. 

I encourage you to learn more about this Act. Our streams across Loudoun need help. We’ve been monitoring our local streams for 14 years along with other organizations in Loudoun and we have the data to show that they are in trouble. We also know that preserving and restoring the buffers along streams helps improve water quality and the overall health of our environment.

Dave Thomas had a wonderful experience this past spring and was kind enough to write up his observations for us here. I’ll include a few of the photos in this post but will put the full album of the 20 photos on our Facebook Album. It’s a wonderful visual chronology!

Red-shouldered Hawks Nesting at Lansdowne, March — June, 2010, by Dave Thomas

In February, a few residents of our condominium in Lansdowne (part of Leisure World of Virginia) noticed a pair of hawks being very active around a tall oak tree behind the rear parking area of our 11-story building.  For those who know the area, the oak is less than 100 yards from the property boundary with our neighbor, Landsowne Resort.

The hawks took over a squirrel’s nest nicely located at a large tree fork opposite the ninth floor. They then greatly enlarged the nest and drove off squirrels that occasionally came back to look.

During March the pair evidently mated and settled in.  Even before the trees leafed out, however, the interior of the nest was impossible to view, so we could not be sure when and how many eggs were laid.  Much later, it became clear that one young hawk was being raised.

The twenty photographs and captions capture a fragmentary “natural history” of the story as it unfolded.  Even though the photography was difficult, and still distant despite a good telephoto lens, it was a “once-in-a-lifetime” experience for us.

The photographs are selected from well over 1000, most of them sequences at six frames per second to capture fleeting moments. 

For example, the snake was visible in successive photos both approaching the nest and being fed to the young hawk. Unfortunately, sharp focus is often difficult to achieve, but the events were faithfully recorded.

I thank many neighbors who watched developments carefully and kept me informed, and Loudoun Wildlife Conservancy members who identified the hawk species and nesting behavior.  Finally, I have greater awe than then ever of the remarkable work done by dedicated and talented nature photographers. –Dave Thomas

On July 24th, Del Sargent led the regular monthly Loudoun Wildlife Conservancy bird walk at the Blue Ridge Center in northwestern Loudoun Co.  At the same time Marcia Weidner & Joe Coleman led a small group of Cub Scouts and their parents on a much shorter walk in both time & distance.
 
As Del wrote: Five very heat tolerant birders braved the hottest day this year in Loudoun County to trek the woods of the Blue Ridge Center for Environmental Stewardship.  We planned our walk so that we were generally in the shade, which was basically the Farmstead Loop.  The big find for the day was a family of KENTUCKY WARBLERS with very impatient young begging for food.  Two Black Vultures sat on the roof of the house where they were probably hatched.
 
It was an int’g day w/the butterflies already active at 6 am and most birds quiet by 8 am.
 
Information on the Blue Ridge Center for Environmental Stewardship which is open every day of the year can be found at http://www.blueridgecenter.org.   Information on the Loudoun Wildlife Conservancy many free walks and programs can be found at www.loudounwildlife.org
 
A total of 36 species on both walks were tallied:
Great Blue Heron, Black Vulture , Turkey Vulture, Mourning Dove, Yellow-billed Cuckoo , Ruby-throated Hummingbird, Red-bellied Woodpecker, Northern Flicker, Pileated Woodpecker, Eastern Wood Pewee, Acadian Flycatcher, Red-eyed Vireo, American Crow, Fish Crow, Tree Swallow, Barn Swallow, Carolina Chickadee, Tufted Titmouse, White-breasted Nuthatch, Carolina Wren, Blue-grey Gnatcatcher, Eastern Bluebird, Wood Thrush, European Starling, Cedar Waxwing, Louisiana Waterthrush, Kentucky Warbler. Common Yellowthroat, Scarlet Tanager, Eastern Towhee, Field Sparrow, Indigo Bunting, Common Grackle, Orchard Oriole, American Goldfinch, House Sparrow

On July 17, a total of 12 people found 17 different butterfly species on a very hot & humid Butterfly Walk at the Blue Ridge Center.  Most of the two-hour walk was spent on the organic farm which was, by far, the most productive spot we visited.  The reason for this was that with the exception of some thistles, little was flowering in the fields.  However, it looks like a lot of the late summer flowers should be blooming in time to make the Blue Ridge Center a great place to visit for our Annual Butterfly Count on Saturday, August 7.
 
While there were a lot of butterflies, there wasn’t as much variety in species as expected.  The highlight of the walk was an AMERICAN SNOUT that landed and briefly perched on one of the participants.  Interestingly enough a HACKBERRY EMPEROR, as they are prone to do, landed on the same individual a little while later and wouldn’t leave. 
 
Most of the butterflies we saw were CLOUDED SULPHURS and SULPHURS, though there were also a fair number of EASTERN TIGER SWALLOWTAILS, including several dark morph female, EASTERN TIGER SWALLOWTAILS.  We also saw Spicebush Swallowtail, Cabbage White, Eastern-tailed Blue, Variegated Fritillary, Great Spangled Fritillary, Pearl Crescent, Silver-spotted Skipper, Horace’s Duskywing, Least Skipper, Peck’s Skipper, Little Glassywing, and Dun Skipper. 
 
Three weeks ago during the regular monthly bird walk on June 26, when a lot more was blooming, we had more diversity and in addition to the above butterflies also saw Pipevine Swallowtail, Zebra Swallowtail, Meadow Fritillary, Red-spotted Purple, Northern Pearly-eye, and Monarch butterflies.

Five of us birded the Banshee Reeks Nature Preserve on July 10.  When we arrived the rain was still coming down pretty heavily but by 8:15 had tapered off considerably and was finished by 8:30 am.  Because a lot of the birds were very wet fledglings identification was rather tough for the first hour or so and resulted in some rather int’g discussions over behavior and shape.  And of course none of us had a guide with us that showed fledgling plumage well.  It was a lot easier after it dried out.
 
The highlights at Banshee included a lot of Blue Grosbeaks, prob. more than most of us have ever seen before, including some recently fledged youngsters begging as well as beautiful adult males.  We also had very healthy numbers of Common Yellowthroats, Yellow-breasted Chats, Eastern Towhees, Field Sparrows, and Orchard Orioles.  Many of these were also recently fledged and begging birds.
 
After wrapping up at Banshee Reeks, Donna Quinn & I drove over to the Dulles Greenway Wetlands Mitigation Project where we spent a little less than an hour and found several shorebird species including four SHORT-BILLED DOWITCHERS.
 
The regular monthly free bird walk (every 2nd Sat) at the Banshee Reeks Nature Preserve is sponsored by the Loudoun Wildlife Conservancy (www.loudounwildlife.org) and the Friends of Banshee Reeks (www.bansheereeks.org); information on both and their upcoming events can be found on their websites.  On these Saturdays, depending on the weather & the time of the year, we often visit the Dulles Greenway Wetlands Mitigation Project either before or after the Banshee walk.

Seven birders joined Loudoun Wildlife Conservancy for a very pleasant bird walk at the Blue Ridge Center for Environmental Stewardship on Saturday, June 26. 

We met and spent a few minutes birding the area right around the Visitor Center before and after the main walk in the central portion of the Center.  Not only did we hear a Yellow-billed Cuckoo in the woods next to the Visitor Center we were entertained by a couple of YELLOW-BREASTED CHATS, one of which was very vocal and active right next to where we were tallying at the end of the walk. 

Because of the heat we headed over to Arnold Rd and spent most of the morning’s walk in the center’s extensive woods and followed a variety of trails crossing Piney Run twice and Sweet Run twice as well. 

We did spend about 30 minutes on the Butterfly Alley Trail along the powercut where we heard BLUE-WINGED WARBLERS, a couple more chats, and saw several butterflies – including this fresh Pipevine Swallowtail shown in the photo by Norm Gresley.
 
In addition to watching CEDAR WAXWINGS courting we picked up nine warbler species, including a CERULEAN, a KENTUCKY, a REDSTART, a couple of OVENBIRDS, great views of a vocalizing LOUISIANA WATERTHRUSH, and one WHITE-EYED VIREO along with numerous ACADIAN FLYCATCHERS, RED-EYED VIREOS, BLUE-GRAY GNATCATCHERS, and INDIGO BUNTINGS.  As we were walking back to our cars after tallying we got great views of a GRASSHOPPER SPARROW vocalizing.
 
Additionally we saw quite a few butterflies species including a PIPEVINE SWALLOWTAIL, a couple of Zebra Swallowtails, several Great-spangled Fritillaries, a Meadow Fritillary, several Red-spotted Purples, a very worn Northern Pearly-eye, and a Monarch.

banshee-calico-pennant-jun-15-2008-4Happy Summer Solstice! This is the day of the year when we have most number of hours of daylight…longest day of the year here in the northern hemisphere, while it’s the shortest day of the year in the southern hemisphere.

If you’ve been doing a photo journal of nature through the seasons, today is the day to go back out to your special nature spot and get your picture. We started this last fall with the Autumnal Equinox, so if you did each season you should now have four seasonal views of your nature spot.

I think its pretty neat to take a look at a place from this perspective – all the changes – the sights, the sounds, the smells – yet with the familiar at the foundation. Have a happy day.

In June as many as a dozen species may burst their buds on a single day. No man can heed all these anniversaries; no man can ignore all of them.
