The state of Maryland has a host of symbols, ranging from iconic, such as the Baltimore oriole and the diamondback terrapin, to trivial, like the state’s official sport of jousting or milk as the state’s official beverage.
Delegate Mary Ann Lisanti, D-Harford, is proposing a bill that would add a new state symbol: the canvasback duck, also known as the “King of Ducks,” as the state waterfowl.
The duck would be the first state symbol added officially since 2008, when walking became the state’s official exercise and Smith Island Cake became the state’s official dessert.
“The symbol of that culture is the canvasback,” she added.
Canvasback ducks have a longstanding history in the state of Maryland, according to Chris Sebastian, a public affairs coordinator for DucksUnlimited.
Canvasback ducks, which use the Chesapeake Bay as a winter migration destination, have a “strong connection” to the bay, Sebastian said in an email.
“Historically, the bay supported more than half of the continental population of canvasbacks during winter. … Groups of people will gather near Cambridge, Maryland, along the Choptank River to see large flocks of birds.”
Today, the largest threat to the birds is the “deterioration of water quality in North America,” Sebastian added.
The ducks’ preferred food, sub-aquatic vegetation, is becoming scarce in the Chesapeake and, as a result, they are beginning to shift their migration patterns further south into the lower Mississippi Alluvial Valley.
Diminishing water quality in the 1970s led to a significant drop in the number of canvasback ducks in the area, Lisanti said.
“They disappeared. We didn’t have a lot of them,” Lisanti said. “Now that the bay is turned around with a lot of our environmental regulations that have taken hold they’ve come back. (Canvasback ducks) are not only a symbol of our past but they are also a resilience symbol of the health of our bay.
Data from year to year is not directly comparable because the count of the migratory birds is affected by a number of factors, including weather conditions.
According to Josh Homyack, a waterfowl project leader the Maryland Department of Natural Resources, the midwinter survey has been conducted since the mid-1950s and is normally carried out by states on behalf of the federal government. Homyack said that the data should not be compared year to year but rather examined as five- to 10-year trends.
The traditional annual survey used for the species count of canvasbacks is normally taken in their northern breeding grounds, throughout the northern Plains, Canada and Alaska, during the summer.
