TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of April 17, 2017.

MUSIC – ~ 13 sec – Excerpt of “Red Wing” by The Steel Wheels.

This week, music from the Harrisonburg, Va.-based band The Steel Wheels introduces a mystery sound that’s common to Virginia’s wet areas.  Have a listen for about 10 seconds, and see if you can guess what’s making the three-note song.  And your hint was in the music you heard!

SOUNDS - ~10 sec

If you guessed a Red-winged Blackbird, you’re right!   Found year-round throughout Virginia, this bird is often seen, and distinctively heard, around ponds, marshes, streams, and other wet areas.  A black body with red-and-yellow shoulder patches makes the males easy to identify; females, though, are brownish and lack the shoulder colors.  The Red-wing is one of five North American species of blackbirds, and one of about 20 North American species categorized in the family that includes blackbirds, cowbirds, grackles, meadowlarks, and orioles.

The Cornell Lab of Ornithology describes Red-wings as “perhaps the most abundant and most commonly studied bird of North America.”  This species feeds on insects during the nesting season but later in the year switches to grains and seeds, with impacts in some cases on corn, sunflowers, and other crops by birds gathered in large, mixed-species flocks.  About the flocking characteristic, authors Alice Jane and Robert Lippson—in their 2006 book Life in the Chesapeake Bay—wrote that “as fall approaches, [Red-wings] throng in huge mixed flocks with grackles and cowbirds...[gathering] in great clouds and [spiraling] in long, seemingly never-ending smoke-like plumes” until they “suddenly descend into a grove of trees.”

Thanks to The Steel Wheels—who put on a summer festival called the Red Wing Roots Music Festival—for permission to use this week’s music, and we close with a few more seconds of “Red Wing.”

MUSIC - ~33 sec

One of many Red-winged Blackbird habitats: Stroubles Creek along Plantation Road on the Virginia Tech Campus in Blacksburg, where the bird sounds used in this episode were recorded on March 17, 2017.

Red-winged Blackbird painting originally published between 1827 and 1838 by John James Audubon in Birds of America (plate LXVII [67]), as reprinted in 1985 by Abbeville Press, New York.  Audubon titled the painting “Redwinged Starling or Marsh Blackbird—Icterus phoeniceus,” but it is clearly the Red-winged Blackbird (scientific name Agelaius phoeniceus).  A Red-winged Starling (scientific name Onychognathus morio) is an African species with a much different appearance (see http://www.oiseaux-birds.com/card-red-winged-starling.html).  The painting includes an adult male (top), young male (middle left), adult female (middle right), and young female (lower), accompanied by blooming Red Maple branches.  Photo taken April 17, 2017, from the reprint copy (no. 6 of 350 copies printed in 1985) owned by Special Collections of Virginia Tech Libraries.  Information about Birds of America is available from the National Audubon Society, online at http://www.audubon.org/birds-of-america.  Also, a list of the Birds of America plates in numerical order, by volume, is available from the University of Pittsburgh, online at http://digital.library.pitt.edu/a/audubon/plates.html.  Virginia Water Radio thanks Virginia Tech Libraries' Special Collections for permission to take photos from their copy of Birds of America and for their assistance.
