From Donald Kroodsma’s The Singing Life of Birds: The Art and Science of Listening to Birdsong.

Formal study of birdsong has long been fascinated with the who, how, and why of some of our most ubiquitous outdoor sounds. Many guides encourage new birders to learn their species by ear, listening for bird presence rather than relying on sight alone. Researchers have examined everything from a songbird’s syrinx (the bird equivalent of a larynx) to its wing morphology to determine how a bird makes its song. Ecologists have monitored bird behavior to suggest why they sing and why birdsong makes us feel happy and safe. (For further thoughts on birdsong as a cultural ecosystem service, take a look at my research proposal on the valuation of birdsong in education.)
As a student of an Applied Wildlife Management course and an avid musician and fiddler, and a complete beginner when it comes to birds, I decided to examine the what of birdsong. More specifically, I was curious about the musical what, the pieces and patterns of sound that make up a spring morning or summer evening. Do birds sing in pitches and tones like we do? Do they prefer certain keys? Do they take a breath with each phrase? And how hard could it be to learn to reproduce birdsongs? (Quite hard, it turns out).

I remained still underneath a swirling aquatic world. Corals of brilliant blue and pink mixed with fish of bold black and yellow. Water of crystal clarity ebbed and flowed towards gorgeously blond sand. Sea anemone wavered and I watched, transfixed, as the bulging eyes of a massively prehistoric stingray reflected the wonder of it all.
As the sea swelled, forty violins soared to a grandiose peak. As a wave smashed on the rocky shore, cymbals crashed and drums bellowed. And as the wave dissipated, a bassoon emerged from lonesome depths where a barrier shark swam far from the colorful critters near the sun’s dancing rays.
It took three wave and cymbal crashes before I realized that this music of the sea had been choreographed with Hollywood precision. As a tourist in the Georgia Aquarium in Atlanta, I was listening to the soundtrack of nature, piped in through the invisibly scattered speakers that followed my trail and amplified my mood. Those soaring chords and delightful suspensions latched onto my wonder and awe, building my anticipation and enhanced my excitement when the belugas breeched or the sea lions wrestled.
But was this a bad thing? The music kept me focused, adding drama to the already dramatic, while drowning out the hoards of young families that mixed in with my own. Carefully arranged and built to sell, this supposed music of nature sets the mood that inspires us to linger a while, more so than perhaps, these days, silence can.
Of course, real nature is not silent. Winds sweep, critters cluck, wolves howl and woodpeckers tap. So do other animals hear music in nature? What about insects, reptiles, or microbes? What do they hear? Continue reading

It has happened countless times: I walk into my favorite restaurant only to find that it is out of breakfast burritos. The manager points me to the tamales without ever explaining if it was a lack of eggs, a problem with the oven, or an angry mob of hungry burrito-eaters that wiped out the supply this weekend. I leave hungry and find somewhere else to eat.
These days, the red knot birds in Delaware Bay are similarly exasperated, but with no other food to eat when their seasonal feast of horseshoe crab eggs are gone, the migratory birds are starving. Horseshoe crabs are the favored bait for a growing market of eel and conch farms, diminishing the supply and diversity of breeding horseshoe crab pairs left in the bay. Continue reading
We all have our routines, those mental checklists we complete to make sure that our day will run smoothly. Some are entirely rational, others seem almost ridiculous, but all are part of what makes our own worlds go around. One of my self-affirming habits each winter evening is to look for Orion, to make sure that his giant frame is poised for battle in the night sky as he has been since the ancient Greeks raised his mortal body into the heavens almost 3,000 years ago.
Orion’s nighttime traverses actually began long before the Homer immortalized his character in The Iliad. The configuration of the constellation has been visible from Earth for about 1.5 million years and should stay recognizable for about 1 to 2 million more years. Ultimately, the stars will rotate within our galaxy and change their relative positions to each other, as well as to Earth. In the current wintertime sky, Orion routinely rises in the south to southeast at sunset, big and broad, early enough to entertain those of us who aren’t night owls. Betelgeuse, the supergiant that is his right shoulder, is by far the reddest object on the dark horizon and holds the allure that it may explode at any moment, collapsing under its own weight and rebounding into fiery supernova glow. The odds that this impressive event will occur tonight are “astronomically small,” but it is always worth another look.
