WHITE FEATHERS

THE NESTING LIVES OF TREE SWALLOWS

Definitely one for dyed-in-the-wool bird lovers.

A search for the answer to a seemingly trivial question—why do tree swallows line their nests with white feathers?—reveals much about the nesting behavior of these wild birds but even more about the lifestyle of a dedicated scientist.

Heinrich (Emeritus, Biology/Univ. of Vermont; The Naturalist's Notebook: Tracking Changes in the Natural World Around You, 2017, etc.), a prolific author and naturalist, is no casual observer of nature. Each spring from 2010 to 2018, the now-retired professor sat quietly for hours watching tree swallows, counting, measuring, recording, and conducting experiments. He focused on a single pair of tree swallows, first in Vermont and then from his cabin in Maine. Rising sometimes before dawn, he recorded to the minute the birds’ behaviors: “Finally, at 6:46 a.m., he landed on the box, peeked in, and flew back up to perch quietly on the locust tree until 7:12 a.m.” Heinrich kept precise tabs on when the migrating birds returned, mated, built a nest, and laid eggs as well as when the eggs hatched, how often the chicks were fed, and when they fledged. The affinity of tree swallows for white feathers puzzled him, and he conducted experiments with feathers of various sizes and colors, even with strips of toilet paper when no feathers were available. The answer to the white feather puzzle he offers here is appealing but one that he admits needs further testing. As he writes, “eight years observing ‘my’ swallows’ behaviors related to white feathers yielded both fascination and frustration.” The author provides more information about the nesting behavior of tree swallows than most general readers will want to know, but the picture that emerges of a naturalist at work is impressive. Illustrations include eight pages of his own black-and-white close-up photographs and a scattering of delightful drawings of trees, nests, birds, feathers, and eggs.

Definitely one for dyed-in-the-wool bird lovers.

WHY FISH DON'T EXIST

A STORY OF LOSS, LOVE, AND THE HIDDEN ORDER OF LIFE

A quirky wonder of a book.

A Peabody Award–winning NPR science reporter chronicles the life of a turn-of-the-century scientist and how her quest led to significant revelations about the meaning of order, chaos, and her own existence.

Miller began doing research on David Starr Jordan (1851-1931) to understand how he had managed to carry on after the 1906 San Francisco earthquake destroyed his work. A taxonomist who is credited with discovering “a full fifth of fish known to man in his day,” Jordan had amassed an unparalleled collection of ichthyological specimens. Gathering up all the fish he could save, Jordan sewed the nameplates that had been on the destroyed jars directly onto the fish. His perseverance intrigued the author, who also discusses the struggles she underwent after her affair with a woman ended a heterosexual relationship. Born into an upstate New York farm family, Jordan attended Cornell and then became an itinerant scholar and field researcher until he landed at Indiana University, where his first ichthyological collection was destroyed by lightning. In between this catastrophe and others involving family members’ deaths, he reconstructed his collection. Later, he was appointed as the founding president of Stanford, where he evolved into a Machiavellian figure who trampled on colleagues and sang the praises of eugenics. Miller concludes that Jordan displayed the characteristics of someone who relied on “positive illusions” to rebound from disaster and that his stand on eugenics came from a belief in “a divine hierarchy from bacteria to humans that point[ed]…toward better.” Considering recent research that negates biological hierarchies, the author then suggests that Jordan’s beloved taxonomic category—fish—does not exist. Part biography, part science report, and part meditation on how the chaos that caused Miller’s existential misery could also bring self-acceptance and a loving wife, this unique book is an ingenious celebration of diversity and the mysterious order that underlies all existence.

A quirky wonder of a book.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.

These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both scientists and general readers.
