Why do birds sing so loudly in the morning in spring? It’s the ‘dawn chorus’ 

As spring begins, so does a fresh song at daybreak, unique to the season. Just before the sun rises, birds start singing their melodies, creating a chirpy symphony.

This phenomenon is known as the dawn chorus, and it’s special for a number of reasons: There are more birds singing at this time of year, and they also sing more often. This energetic burst of birdsong is often louder than usual too. The dawn chorus’ early morning explosion of sounds has even inspired multiple poems and songs.

“It's the epitome of spring,” says Jordan E. Rutter, an ornithologist at the American Bird Conservancy. After the long and cold winter, “all of a sudden you have this influx of so many beautiful birds coming back and singing.”

This harmony of birdsong at dawn happens during a fundamental time of the year. The dawn chorus is, in fact, mostly composed of birds of both genders singing to find a mate so they can breed (though males may sing more).

“There is such a large increase in quantity of song by individuals and the collective,” Rutter says. “These birds sing louder to literally be heard. They need to compete with each other as well, and the louder the better in regards to who is the most impressive mate.”

During this time, males also sing to assert their dominance and claim their territory. “Those songs are how they communicate to other males of the same species, or even just other birds and predators in general, and say, ‘This is my home,’” says Rutter.

In the United States and Canada, the dawn chorus can be heard roughly from March through May, when many bird species migrate there from their winter homes to breed. Peak dawn chorus times might depend on where you live, Rutter says. For example, April is peak for the southern U.S., but birds in Washington, D.C., will put on the best show in early May. (Alternatively, in the tropics, the dawn chorus can be heard almost any time of year, as many birds have a prolonged breeding season in those warmer climates.)

Why is it a ‘dawn’ chorus?

But why birds sing in the early morning is still “an open question,” says Mike Webster, an ornithologist at the Cornell Lab of Ornithology. “There's a lot of debate, and I don't think there's any consensus on exactly why it is that everything happens at dawn."

One hypothesis is that weather conditions at daybreak make it easier for birdsong to travel.

“In general, sound travels farther when the air is cooler and more dense. Sound also transmits more clearly (and very slightly faster) when humidity is higher so that details of the song do not degrade as much over distance,” says Heather Williams, a professor at Williams College who has studied the neuroscience of birdsong. She notes that wind may also impede sound transmission. “At dawn, the cooler air results in decreased winds at ground level, so coupled with the higher humidity, sound carries farther and more clearly, with less distortion.”

Millennials are giving Gen Z advice for their first potential recession

Many of the generation were young adults when the Great Recession began, and to this day, they struggle to buy homes and pay off student debt. Now these jaded millennials are sharing their wisdom with Gen Z on TikTok, posting preparation tips and no-buy lists to ease the minds of young people who could be entering their first major recession as adults.President Donald Trump’s whiplash-inducing policy changes have everyone warning about dire consequences for the US economy, from Fed Chair Jerome Powell to Goldman Sachs analysts. The Trump administration’s tit-for-tat escalation in the global trade war could lead to a recession for both the US and the world this year, JPMorgan said this month. It comes during an already unprecedented string of events for young people — people in their early 20s are earning less and have more debt, already battered by the Covid-19 pandemic and an onslaught of inflation.

So, the United States might not be in a recession right now, but its youngest working adults are still anxious — and seeking advice from their older peers. When scrolling through TikTok, Sasha Whitney, 37, noticed Gen Z users shared the same feelings over an impending recession: “downtrodden, frustrated, very bleak and hopeless about the future.” 

It’s a stark difference from when Whitney graduated from college in 2009 during the Great Recession, before social media became as pervasive and when Barack Obama, who ran his campaign on the concept of hope, just took office.

    400 million people speak English as their first language; another 1.4 billion as a second tongue. Born 1,600 years ago among the Germanic tribes of northern Europe, English became global. A new exhibition at the British Library, named Evolving English, traces for the first time the incredible journey launched by the Frisians, Saxons, Angles and Jutes who sailed to southeast England, and whose descendants created the Vespasian Psalter in the eighth century. From the Vespasian Psalter the journey moves on through England’s early literary heroes, Beowulf, Sir Gawayne and the Grene Knight, and on to Jonathan Swift.

    The curators of Evolving English have been clever to focus not just on English at school and English at work, but English at play, from spoonerisms to malapropisms, puns and palindromes and the 1,800 words invented by William Shakespeare — among them “green-eyed”, “go-between”, “well-read” and “zany”. Not only was Shakespeare the greatest English writer, he could have been no other kind.

    As a science fiction writer, Octavia Butler forged a new path and envisioned bold possibilities. The future she wrote about is now our present moment. She wrote 12 novels and won each of science fiction’s highest honors. In 1995, she became the first science fiction writer to be awarded a MacArthur “genius” grant. She is also, increasingly, a writer recognized as one of the most important voices and visionaries of the 20^th century, and now the 21^st. As a Black woman and a writer, Butler demolished walls that seemed impermeable, writing on themes that seemed uncategorizable. Her ideas and characters continue to resonate with new readers when so many are looking for, if not hope, then a map for a way forward.

    Her vision about the climate crisis, political and societal upheaval and the brutality and consequences of power hierarchies seems both sobering and prescient. However, as Butler often noted, being right was never the point. She didn’t want to be right — far from it. She wanted to give us time, and tools, to correct the course.
