English Sparrows Seen As A Nuisance


I seldom see English (house) sparrows around our place anymore. Nor or they as visible around downtown North Augusta or shopping centers as I remember them not too many years ago.

Our most familiar bird alien is the English sparrow. After its introduction in the 1850s in New England, it took less than fifty years for it to "capture" the country, establishing itself in California and other western states by the 1890s.

Perhaps more than any other feathered creature, this sparrow takes advantage of man's progress. Its rapid spread across the country was not only by its own wings but it has been attributed to its bumming a ride in cattle railroad cars loaded with grain from which it fed en route to the west coast. Free ride, free food, free shelter. Why not go for it? And it did!

Sparrows are mainly seed eaters and rural America was just their thing. When these brown-backed birds first arrived in the States in the 1850s no gas guzzling machines existed. All local transportation was by wagon, buggy, carriage or cart, all driven by grain-eating horses. Much grain was dropped around these animals and sparrows followed wherever the animals went.

Some people say the house sparrow is a pest and call it a tramp, a hoodlum and a gamin . . . a sort of street urchin . . . for years ago it was a city dweller.

This little free loader also has a talent for multiplying and is known as the mouse of the bird world, hatching brood after brood from early spring through late fall. But now his numbers are decreasing, possibly because horses have been replaced by automobiles and his food supply is dwindling.

Our sweet-singing native sparrows are shy little birds that live quiet lives along wood edges and in thickets and grassy fields. Until the 1850s they were the only sparrows in North America.

The house sparrow is really not a sparrow but is of the weaver family of the Old World. Early settlers called them sparrows and the name stuck. It was quite natural to call it the English sparrow since most of the birds were imported from England, though the species is widely distributed throughout the world.

This saucy, keen-witted little gamin, who thrives where other birds would starve, and who insists on driving away other cavity nesting birds such as purple martins, bluebirds, chickadees and titmice by destroying their eggs and young then usurping the house for themselves, is now considered a nuisance.

The decrease in these birds is most marked in the eastern states, especially in the cities and towns, though the sparrows are still common in rural districts around poultry and cattle farms where there is still plenty of grain fed to livestock.

Nonetheless, with all his shortcomings, the male is a good looking chap in his black and hazelnut-striped coat and chestnut, black and white head and black bib. The female looks much like the male but lacks the conspicuous markings about the head and the black bib.

Song wise the house sparrow flunks. All he can usually manage is a harsh chirping and chattering.

Drowsy Days Of July Just Around The Corner

The drowsy days of July are on their way. The hot, brassy sun, the droning of bees and the still, flower-perfumed air seem to voice the peacefulness of the mid-summer day.

It is in the month of July that the new generation of birds, frogs, mammals, yard and garden weeds and other forms of animal and plant life begin to mature and come into their own.

After the hustle and bustle of May and June, July seems to bring a sense of maturity to the young of the feathered tribe and you see them coming to feeders alone. Young cardinals, more than any other young I have observed, seem to be skilled in "working the parents for food" as long as the parents will allow it. Sometimes you will see a good-sized young-of-the-year cowbird being cared for by a vireo or cardinal.

July is the first full month the sun begins its southward journey. Our calendars say summer is just beginning and we like to believe these long, sweet days will last forever. But we know days are now growing shorter and shorter, and will continue to do so until the winter solstice in December.

July, like any other month of the year, has dumped into her thirty-one days left overs of the months before and signs of what is to be in the months ahead. Along roadsides and in abandoned fields, early goldenrods, black-eyed Susans, sunflowers and butter-and-egg toadflax say "autumn" loud and clear.

Somehow we get the idea that trees don't begin to shed their leaves until the calendar says "fall". But look. Some of the trees are beginning to drop colorful leaves now, leaves that are hidden deep within the green tree. Notice the leaves on your lawn. First a yellow one here and there, then an occasional red or wine one. These falling leaves will increase steadily until late October and early November when the last ones are downed by winter winds and rain. Even if we have a wet summer, leaves will drop.

Trumpet vine and jewel weed are the most bounteous in July, just in time for hummers north of us to join our locals, giving our yards more flash over flower beds and lawns as they sip nectar from the feeders.

Killdeer are leading about their spindle-legged fledglings, hatched from a quartet of earth-colored eggs deposited on a slight depression in a graveled plot of a cemetery.

Purple martins, red-winged blackbirds and grackles are early flockers. Already you may see them in small bands in trees or strung along a utility line like a row of beads. The orchard oriole is usually on its way back to the tropics by the end of July, staying in the temperate zone less than four months, just long enough to rear a brood of five brownish-yellowish youngsters. So soon do they vanish from our turf that usually the young-of-the-year are still in juvenile plumage when they arrive in Central America.

During July sunsets begin to change. The sun no longer sets behind the same tree or house as it did before the twenty-first of June. It is slowly moving southward (notice the shadows), and this will bring to the Central Savannah River Area the migration of the million of birds making their way to South and Central America for the winter.

Ruby-throated hummingbirds will be the first to hit our area. Be on the lookout! Some will be fattening up at your feeders in the next few weeks for the six hundred mile trip over the Gulf.

Drought Takes Toll On Birds Too

When hot and sultry days of summer bring thirst to the South and salvia droops and impatiens hang their pretty heads, it is then we must be aware of the needs of birds.

There has been neither dew nor rain for days and a bird must wet its whistle if there is to be song in the red-leafed maple tree. So we turn on the sprinkler.

A bold robin is the first to come under the delightfully refreshing drops. He smacks his beak as if he's tasting the wet stuff. Evidently he's delighted with the taste. He fluffs his feathers, shakes himself like a feathered Elvis, then smacks his beak again. He moves into the pool, dimpled by drops of water from the sprinkler.

A female towhee flutters down timidly to sip the water. Acting as if she's on her lunch break, she stays but a moment, just long enough to take a quick shower. That darling of the yard, the chickadee, comes floating in and alights ever so lightly upon a rock washed by the flowing water.

The robin has moved farther into the pool, standing knee-high in the water and seems to close his eyes. A fat bee is droning on the begonias. The day is drowsy with noon.

Yellow eyes gleaming, a brown thrasher plunges into the pool, disturbing the sleeping robin, who, frightened, bolts away. Bathing and fluffing his feathers, the thrasher seems to be bold and self-assured. But wait, here comes a blue jay screaming his head off, followed by another. It looks as if he well alight on the thrasher and that's enough to make Mr. Bold Guy fly away through the shrubbery, leaving the pool to the jays.

Bathing, shaking wet feathers, preening . . . the jays take over for some minutes. One scolds. Not another bird in sight. Evidently the scold must be for the mate, who must be crowding him in the shower. They take another bath but use separate tubs this time. Now they are gone.

Empty of avian creatures for awhile, the pool soon plays host to a small band of house finches, probably mama, papa and four young. They bathe in the water, then one rises in a tiny welter of spray, scuds with tingling wings to the edge and perches there on the rocks, tossing a shower around him.

No summer day, and especially one with a pool of clear water, can get by without a visit from the troubadour, the mockingbird. He stands on the rocky edge, raises his tail and wings, pulls them down, then drops onto the silvery rocks barely covered with the gurgling water. Splashing and flashing, wetting himself all over, he finally hops onto the edge of the pool and fluffs his feathers.

Before he is through with his primping, house finches again descend on the pool, look it over, and without drinking or bathing, leave. Under the refreshing spray are two gray-bodied, pink-footed doves.

A noisy Carolina wren, poking in and out all the rock crevices around the pool, finds the little waterfall refreshing as he hops hurriedly through it, bursting into song as he flies away.

Hidden in the red-leafed maple tree, a robin is signing a song to the hot summer day.

Look-alikes Can Fool Birders


For the beginning birder, look-alikes are tormenting.

First, let's take the house finch and the purple finch. The purple finch, of course, is not in the Central Savannah River Area except during winter months but a beginner might not know this and will confuse the two finches.

Arriving in our area in late November and early December, the purple finch is a purplish rosy-red, while the color of the house finch is usually a bright fire-truck red. The male purple finch looks as if he's been dipped in "cranberry juice", giving his brown feathered back an overall purplish look. The rosy color of the purple finch's throat and breast blend into the white of the belly. The brown-backed house finch has a brown-streaked breast and belly while the purple finch has a plain rosy breast.

Female purple finches have a distinct face patch defined by a whitish eyebrow line and cheekstripe. They are heavily streaked overall with dark brown on a white background.

Female house finches have light brown streaks on a beige background and lack the eyebrow line and cheek stripe and are slimmer.

Other look-alikes are the mockingbird and the loggerhead shrike, both permanent residents of the Central Savannah River Area. Though both birds are gray and white, and both have solid white breasts and gray wings with white patches, the grays are different shades.

The shrike's gray is almost a charcoal color while the mockingbird's feathers are a soft, light gray. The mockingbird has a slim bill. The shrike's is dark, short and hooked. Another distinguishing field mark of the shrike is the black eye mask. And he is a stouter bird than the mockingbird, though not as long.

Summer tanagers are solid red, sometimes with a dark washing on the wings and tail. The trouble here are the females, with the summer tanager looking much like the female orchard oriole, both summer residents of this area. Both are yellow, though in slightly different shades. Oriole beaks are dark, sturdy and pointed. Tanager beaks are not as long as the oriole's and are blunt at the tip and are whitish in color. The female orchard oriole has grayish wings with white wingbars. Wingbars on the tanager are hardly noticeable.

The wood thrush is a summer visitor, the hermit thrush a winter tourist. Usually, the wood thrush is on his way to Central America before the hermit arrives for the winter, though sometimes they meet in the South long enough to say "hello". Both thrushes are brown-backed, with off-white, brown-spotted breasts. Look at the head and tail to distinguish the two. The wood thrush has a reddish-brown head, with duller brown on the wings, back and tail. The hermit thrush has a reddish-brown tail, with the remainder of its body a duller brown.

There are two wrens that you might see around your place during the colder months . . . our State bird, the Carolina wren and the little mousy winter wren. The winter wren is much smaller than the Carolina, with a short, stubby tail, grayish-brown back and barred belly. The Carolina's back is reddish-brown and its belly is buffy, not white, and it has a strong eye line. There's little risk that these two wrens will be confusing.
