Birdsong has inspired humans for centuries: is it music?

Avian choristers have long inspired listeners from all walks of life. It seems fair to ask if birdsong is simply a hard-wired, functional, primitive sound – or could we call it “music”?

Both sexes of pied butcherbirds participate in daytime group singing. However, their solo songs are principally nocturnal and may last as long as seven hours. Each adult soloist sings partially or even completely differently from another, and solo songs transform each year.

Intriguingly, these songsters share many musical sounds and behaviours with human musicians, including approaches to repetition and variation, and shape and balance. Pied butcherbirds are not unique. We also find overlaps with our sense of musicality in the vocalisations of species like nightingales, European blackbirds, and humpback whales.

Most of the human population now lives in urban areas. But the growth of these urban landscapes is something that we can only partially appreciate from the ground. Instead, we should also look from the sky. Imagery produced from satellites and infrared technology shows the ingenuity and expansion of cities, the symbiosis of urban and natural landscapes and how a changing climate is also changing the places most humans call home. Our goal as remote-sensing scientists — and the aim of our new book, City Unseen: New Visions of an Urban Planet — is to offer insights from these satellite-enabled perspectives.

Judith Wallerstein and divorce: how one woman changed the way we think about breakups.

Judy went to the Berkeley library to see what had been written about how children react to divorce. And found nothing.

The remedy was the “California Children of Divorce Study” which Judy and her colleague Joan Berlin Kelly launched in 1971. They recruited 60 families with 131 children between the ages of 3 and 18 at the point the marriage dissolved, when life as everyone knew it began to unravel. The parents were middle class and well educated. The children had been well cared for.

Judy personally interviewed every man, woman, and child at the time of separation (followed by divorce) and, for the vast majority, every five years afterward for the next quarter of a century. The study turned into an unprecedented longitudinal examination of the effects of divorce on the American family.

Judy’s methodology was based on intimate case studies. She talked with each person over many hours, probing for feelings and insights. For years, she held each child “in her head,” remembering every dream they reported, every fantasy, every frustration. Huge files containing these case studies are still stored downstairs at her home on Belvedere Island in Marin.
