TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of December 11, 2017.
MUSIC – ~9 sec
That’s the tune of “Ducks on the Pond,” attributed to the late Henry Reed, a traditional musician who lived in Giles County, Va., and performed here by Timothy Seaman of Williamsburg. The music sets the stage for this week’s mystery sound from a familiar duck on Virginia’s wintertime ponds and other waters. Have a listen for about 10 seconds and see if you can guess what’s making this descending series of quacks. And here’s a hint: the color of money will help you wing this deal.
SOUND - ~10 sec
If you guessed a Green-winged Teal, you’re right! The Green-winged Teal is one of two teal species found in Virginia—the other is the Blue-winged. According to the Virginia Deparment of Game and Inland Fisheries, the Green-winged is a common coastal Virginia winter resident, and an occasional breeding-season resident, while the Blue-winged sometimes breeds along Virginia’s coast but is more commonly seen during migration. Both these teal are found on ponds, lakes, wetlands, and estuaries, including the Chesapeake Bay.
The names green-winged and blue-winged refer to the colored, iridescent feathers of the birds’ speculum, a rectangular area on their wings’ trailing edge, more noticeable when the birds are flying. Of the Blue-winged Teal, John James Audubon in the 1800s wrote that “When flying in flocks in clear sunny weather, the blue of their wings glistens like polished steel.” A distinctively-colored speculum is charactistic of the sub-family of waterfowl that includes teal along with Mallards, the Wood Duck, and several other familiar species. Teal and related ducks are known as surface-feeders, or dabblers, because of their habit of tipping up their tail and stretching their necks underwater—but not diving—to feed on vegetation or small animals. The Green-winged Teal is the smallest dabbler in North America, but what it lacks in size, it makes up for in motion. Again quoting Audubon: “On land, the Green-wing moves with…ease and grace; it can run at a good rate, without entangling its webbed feet; on the water, also, it moves with great ease…[and]…[o]n wing it has no rivals among ducks.”

EXTRA FACTS ABOUT TEAL IN VIRGINIA
On Blue-winged Teal
From the Virginia Department of Game and Inland Fisheries, “Fish and Wildlife Information Service/Blue-winged Teal,” online at http://vafwis.org/fwis/booklet.html?&bova=040057&Menu=_.Taxonomy&version=17508.
“General Occurrence Comments: On the Coastal Plain it is a common transient in the spring and fall, and a rare and irregular winter resident mostly in the extreme southeast. It is a locally uncommon summer (end of April-end of August) resident along the coast. It is rare elsewhere. In the Piedmont it is an uncommon transient in spring and fall, and a rare summer and winter visitor. In the Mountains and Valleys it is an uncommon transient in spring and fall, and a rare summer and winter visitor. ... Habitat association: This species prefers shorelines to open water and also calm waters or sluggish currents to fast water; in Chesapeake Bay, preferred wintering habitat is brackish estuarine bay marshes. Nesting habitat is used most extensively in the Chesapeake Bay area consists of salt-marsh cordgrass (Spartina) meadows with adjoining tidal ponds or creeks. Blue-winged teal typically selects the tallest, most dense herbaceons vegetation available for nesting. … Food habits: The diet is 25% animal matter and 75% vegetable. Half of the animal diet is snails and other molluscs.”
On Green-winged Teal
From the Virginia Department of Game and Inland Fisheries, “Fish and Wildlife Information Service/Green-winged Teal,” online at http://vafwis.org/fwis/booklet.html?&bova=040056&Menu=_.Taxonomy&version=17508.
“General Occurrence Comments: This is a common transient and winter resident on the Coastal Plain, and uncommon inland. Peak counts occur along the coast during winter. … Habitat Associations: They are found in ponds, lakes, sedge meadows, marshes near grasslands, dry hillsides with bushy thickets or adjacent open woodlands. They are generally an upland nester. This species winters in tidal creeks and ponds bordered by mud flats, freshwater marshes, estuaries and coastal brackish marshes. It avoids open salt water. They use available cover for nests but prefer dense stands of grass, weeds, and brush. Nests are usually 2 to 300 feet from water with an average of 95 feet. ...Lives in creeks and ponds bordered by mud flats at low tide. Fresh or brackish creeks and ponds preferred over salt marshes. …Typical nesting habitat: grassland, sedge meadow, dry hillsides with aspen or brush thickets, open woods adjacent to slough or ponds. … General Food Comments: About 90% of diet is vegetation. On mud flats, Green-wing Teals prefer seeds of moist soil plants (nut grasses, millet, smart weeds, water hemp) from previous years as well as insects and mollusks. They will also take the seeds of bulrushes, pond weeds, and spike rushes.”
