Winter’s dark-eyed junco provided inspiration for first column

I wrote my first bird column on Sunday, Nov. 5, 1995, which means this weekly column will mark its 24th anniversary this week. This column has appeared over the last 20 years in a total of six different newspapers, which I regard as a personal achievement as well as an accomplishment for our feathered friends. It’s on their behalf that I pen these weekly efforts to promote conservation and good will toward all birds. “For the Birds” has appeared in the Bristol Herald Courier since June of 2014.

I’ve played detective, helping people identify everything from “rain crows,” or cuckoos, to Muscovy ducks and double-crested cormorants. I’ve observed unusual birds, including white pelican, brant and roseate spoonbill, in Northeast Tennessee and Southwest Virginia and spotlighted them in these columns. I still take delight in the kaleidoscopic parade of colorful warblers that pass through the region each spring and fall as well as the fast-paced duel of ruby-throated hummingbirds. I also offers to sunflower seed and other supplemental food for the resident birds like Carolina chickadees and white-breasted nuthatches.

My first column focused on a common visitor to yards and feeders during the winter months. In fact, dark-eyed juncos should be returning to the region any day. Here, with some revisions I have made through the years, is that first column.

Of all the birds associated with winter weather, few are as symbolic as the dark-eyed junco, or “snow bird.” The junco occurs in several geographic variations.

John V. Dennis, author of “A Complete Guide to Bird Feeding,” captures the essence of the junco in the following description: “Driving winds and swirling snow do not daunt this plucky bird. The coldest winter days see the junco as lively as ever and with a joie de vivre that bolsters our sagging spirits.” The dark-eyed junco’s scientific name, hyemalis, is New Latin for “wintry,” an apt description of this bird.

Most people look forward to the spring return of some of our brilliant birds — warblers, tanagers and orioles — and I must admit that I also enjoy the arrival of these birds. The junco, in comparison to some of these species, is not in the same league. Nevertheless, the junco is handsome in its slate gray and white plumage, giving rise to the old saying “dark skies above, snow below.”

Just as neotropical migrants make long distance journeys twice a year, the junco is also a migrating species. But in Appalachia, the junco is a special type of migrant. Most people think of birds as “going south for the winter.” In a basic sense this is true. But some juncos do not undertake a long horizontal (the scientific term) migration from north to south. Instead, these birds merely move from high elevations, such as the spruce fir peaks, to the lower elevations. This type of migration is known as vertical migration. Other juncos, such as those that spend their breeding season in northern locales, do make a southern migration and, at times, even mix with the vertical migrants.

During the summer months, a visit to higher elevations in southwest Virginia such as Whitetop Mountain or Mount Rogers is almost sure to produce sightings of dark-eyed juncos. Juncos may nest as many three times in a season. A female junco usually lays three to six eggs for each nest, which she constructs without any assistance from her mate.

Juncos are usually in residence around my home by early November. Once they make themselves at home I can expect to play host to them until at least late April or early May of the following year. So, for at least six months, the snow bird is one of the most common and delightful feeder visitors a bird enthusiast could want.

Juncos flock to feeders where they are rather mild-mannered — except among themselves. There are definite pecking orders in a junco flock, and females are usually on the lower tiers of the hierarchy. Females can sometimes be distinguished from males because of their paler gray or even brown upper plumage.

Since juncos are primarily ground feeders they tend to shun hanging feeders. But one winter I observed a junco that had mastered perching on a hanging “pine cone” feeder to enjoy a suet and peanut butter mixture.

Dark-eyed juncos often are content to glean the scraps other birds knock to the ground. Juncos are widespread. They visit feeders across North America. The junco is the most common species of bird to visit feeding stations. They will sample a variety of fare, but prefer such seeds as millet, cracked corn or black oil sunflower.

There’s something about winter that makes a junco’s dark and light garb an appropriate and even striking choice, particularly against a backdrop of newly fallen snow.

Of course, the real entertainment from juncos come from their frequent visits to our backyard feeders. When these birds flock to a feeder and began a furious period of eating, I don’t even have to glance skyward or tune in the television weather forecast. I know what they know. Bad weather is on the way!

Overwintering birds make their return to some familiar area haunts

Mergansers

Now that the warblers, hummingbirds and other birds of summer have, for the most part, departed, new arrivals have filtered into the region to take their place and prevent the winter months from seeming too bleak.

At my own home, these new arrivals have included a field sparrow — the first I’ve seen at home in several years — and a swamp sparrow. I’ve not caught sight of white-throated sparrows or dark-eyed juncos so far, but these hardy sparrows often don’t arrive until the first incidents of truly snowy weather. However, Helen Whited of Richlands, Virginia, emailed me to let me know that she saw her first dark-eyed junco of the season on Monday, Nov. 5.

Different species of waterfowl have also returned to some familiar haunts, and I’m grateful to readers who have kept me informed about some of these arrivals. Joanne Campbell of Bristol, Tennessee, posted on my Facebook page that hooded mergansers have returned to Middlebrook Lake near her home on Saturday, Nov. 3. The hooded merganser, Joanne noted, is one of her favorite birds. Brookie and Jean Potter of Elizabethton, Tennessee, reported that four male buffleheads returned to Wilbur Lake near their home on Oct. 27.

Middlebrook Lake has served as a winter home for hooded mergansers since 1987, while buffleheads have congregated on Wilbur Lake for decades. Another good location to look for buffleheads during the winter months is in the weir below South Holston Dam around the Osceola Island Recreation Area. Several hundred of these ducks have been reported in past winters at these various locations.

Although classified as sea ducks, the mergansers are more at home in river habitats. There are six closely related species in three genera: Mergus, Mergellus and Lophodytes. The latter two genera have only a single species each: the hooded merganser (Lophodytes cucullatus) and the smew (Mergellus albellus).

The typical mergansers are fish-eating waterfowl in the genus known as Mergus. The hooded merganser’s genus name of Lophodytes is derived from Greek and, roughly translated, means “crested diver.” Both male and female hooded mergansers have crests capable of being raised or lowered. Females are mostly brown, but males have a striking plumage in a pattern of brown, white and black.

Everyone has probably heard the phrase “as scarce as hen’s teeth.” It means almost exactly what you think. Birds don’t have teeth, so it’s a way to describe something exceptionally rare. It’s a characteristic that sets birds apart from other creatures, such as mammals.

There are some birds, however, that come closer to having teeth than their other beaked counterparts. Mergansers would definitely fall into that category. The mergansers are a type of duck known collectively as “sawbills,” a reference to their long, thin bills with serrated edges that help them grip prey. The “sawbills” come closer than any of our other birds in having teeth, although not in the same sense as mammals have teeth.

The other mergansers in the Mergus genus consist of four species: common merganser, Brazilian merganser, red-breasted Merganser and scaly-sided Merganser. The last of these is an endangered species with only about 5,000 birds in the worldwide population. These remaining scaly-sided mergansers are found in the border regions of China, North Korea and Russia.

While today’s birds, even mergansers, all lack teeth, that hasn’t always been the case. About 80 million years ago, a bird known as Hesperornis (“western bird”) swam the inland seas that stretched over areas from Kansas to Canada. They swam through those ancient seas because they could not fly.

The body plan of Hesperornis was similar to modern loons and mergansers. Instead of a serrated bill, however, this ancient bird had actual teeth in its long beak. Just like today’s loons and mergansers, it probably fished for its food. At almost six feet in length, however, it dwarfed our modern mergansers and loons and probably fed on larger piscine prey.

This early 20th century illustration of Hesperornis is no longer considered scientifically accurate by scientists, but it does demonstrate one striking feature – the toothed jaws of this ancient bird.

Hooded mergansers are content to seek smaller fish. According to the website for the Ducks Unlimited organization, the hooded merganser is the smallest of the three North American mergansers. In addition to fish, hooded mergansers feed on crayfish and other crustaceans, as well as aquatic insects.

The hooded merganser prefers forested wetlands. As a cavity-nesting bird, it seeks out natural cavities in trees for nesting, although it will also accept nest boxes provided by human landlords. This duck breeds from as far north as Alaska and Canada and as far south as Louisiana and Georgia.

Late fall and winter are good times to see ducks in the region. Some will spend a good portion of the winter season on area lakes, rivers and ponds, while others will make only brief stops during their migration to their preferred wintering grounds. Some of the other ducks that are usually somewhat common in the region in winter include ring-necked duck and American wigeon. If you live or work near a body of water, stay alert for the comings and goings of waterfowl as winter approaches. You may be afforded an opportunity to see a hooded merganser or bufflehead for yourself.
