Observe Intently the Birds

BIRDS inhabit all parts of the earth, and they are among the easiest creatures to observe. What is more, their variety in form, color, song, antics, and habits can make bird-watching, or birding, an entertaining and rewarding pastime.

You may even be able to observe a bird’s daily routine from your kitchen window: a European blackbird digging for worms, a tyrant flycatcher hawking for insects, a dove courting its mate, a swallow tirelessly constructing its nest, or a goldfinch feeding its hungry brood.

Some birds will impress you—such as eagles, falcons, and hawks—as they patrol the skies. Others may amuse you: sparrows squabbling over a tidbit, a male pigeon puffing out its breast to impress a seemingly indifferent female, or a group of squawking rose-pink and gray galahs hanging upside down on a swaying power line as a result of losing their balance. And some sightings will thrill you, such as the overhead passage of migrating storks, cranes, or geese. Indeed, such migrations have been observed for thousands of

years, leaving viewers in awe of the ability of birds to navigate great distances with clocklike precision. .

Today, bird-watching is a popular recreational activity—and understandably so, for birds amaze us with their antics, beauty, courtship rituals, and songs. What is more, they can also teach the thoughtful observer valuable lessons about life. Will you “observe intently the birds”?

The Lantern of the Photuris Firefly

THE lantern, or light organ, of a particular Photuris firefly is covered with jagged scales that dramatically enhance the brightness of the light that the insect produces. * Jagged scales Consider: Researchers have found that tiny scales on the lantern surface of some fireflies form a corrugated pattern, somewhat like overlapping shingles or tiles. The scales tilt up at one end by just 3 micrometers —less than one twentieth the thickness of a human hair. Yet this tiny tilt lets the lantern shine almost 50 percent more brightly than it would if the scales formed an even surface!

PORTRAITS FROM THE PASTIgnaz Semmelweis

IGNAZ SEMMELWEIS may not be a household name, yet his work has benefited most modern families. Born in Buda (now Budapest), Hungary, he received his medical degree at the University of Vienna in 1844. On taking up his post as assistant to a professor at the First Maternity Clinic of Vienna’s General Hospital in 1846, Semmelweis faced an appalling reality —more than 13 percent of the women giving birth there died from a disease called childbed fever. Various theories as to the cause of this disease had been proposed, yet no one had solved the mystery. All attempts to reduce the mortality rate proved futile. Troubled by the spectacle of numerous mothers suffering a slow, agonizing death, Semmelweis determined to find the cause of the disease and prevent it.
