Some interesting waterfowl have spent at least part of the winter at the pond at Erwin Fishery Park and a nearby fenced lagoon at the back of the park.
Some of the visitors since the start of the new year have included green-winged teal, American black duck, lesser scaup and Northern pintail. The scaup is a species of diving duck while the others are what are referred to as “dabbling” ducks. Diver and dabbler refers basically to the manner in which these ducks forage for their food.
The familiar mallard is probably the best known dabbling duck, but other dabblers include American wigeon, gadwall and Northern shoveler. Dabbling ducks generally feed in shallow water.
The green-winged teal is the smallest of North America’s dabbling ducks. There are two other close relatives of the green-winged teal in North America – the blue-winged teal and cinnamon teal. I’ve seen the green-winged and blue-winged at many locations in the region. I saw my only cinnamon teal during a trip to Utah and Idaho in 2003.
The Northern pintail that spent some time at Erwin Fishery Park was a hen with a more subtle appearance than adult male pintails.
This can be a species difficult to find in Northeast Tennessee. The website All About Birds notes that Northern Pintails are common, but their populations declined by about 2.6% per year resulting in a cumulative decline of about 75% between 1966 and 2019, according to the North American Breeding Bird Survey. The Partners in Flight organization estimates the global breeding population at 5.1 million.

Elegant is a useful word for describing pintails. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-brown head down its neck to its mostly white undercarriage. The drake also has attractive gray, brown and black patterning on its back and sides. The hen’s plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. She has the same slender shaper as the male. Her tail feathers are long but don’t match the male’s namesake tapered tail feathers.
The Northern pintail is a cosmopolitan duck that also ranges into Europe, the Middle East, India and Asia. Other pintails include white-cheeked pintail, yellow-billed pintail and Eaton’s pintail. The latter species is restricted to the island groups of Kerguelen and Crozet in the southern Indian Ocean. The species was named after the English explorer, naturalist and entomologist Alfred Edwin Eaton. He served as the vicar of Shepton Montague in Somerset in England. Born in 1944, he died in 1929 at age 84.
Our region offers some dependable locations for looking for winter ducks, as well as other wintering waterfowl such as geese, grebes and loons. Accessible locations for looking for ducks during the winter season include Wilbur Lake near Elizabethton and Osceola Island Recreation Area below the tailwaters of Holston Dam in Bristol. Of course, any farm pond not frozen over is a potential location attractive to wandering waterfowl.
A duck known as the common merganser has expanded its summer nesting range to include the Nolichucky River and Watauga River. Twenty years ago this species, despite its name, was far from common in the region. It’s too early to tell whether changes wrought by last fall’s flooding from Hurricane Helene will affect this duck’s nesting attempts along these two rivers.
One difficulty in finding ducks in recent weeks has been the deep freeze gripping the region and turning almost all open water into ice. The widespread cold could help convince waterfowl from farther north to head south in the hope of less frigid conditions. My hope is that at least a few of those ducks will stop off at places like the pond at Erwin Fishery Park.
Ducks that aren’t too difficult to locate during winter in the region include bufflehead, ring-necked duck and hooded merganser. Other possible visitors include redhead and canvasback. If the Northern pintail is the most elegant of the dabbling ducks, the canvasback ranks as the most majestic of the diving ducks.
Ducks are interesting to observe. Binoculars and spotting scopes can make the process easier. Most ducks are social birds. Flocks, or rafts, of ducks display interesting interactions. In addition to the familiar “quack” of the mallard, different ducks produce a variety of hoots, whistles, hisses and other vocalizations.
