Owls Gone Wild
Flaco, the charismatic Eurasian Eagle-Owl who in February 2023 escaped his enclosure in Central Park Zoo and for a little over a year was the resident célèbre of Central Park, hasn’t been in the news for a while. But at the end of last month, his story, a documentary called Wild Inside, came to the big screen. I went to see it in a packed New York City theater, and what surprised me the most was how much controversy this one owl sparked among local (and national) bird experts at the time.
The Flaco debate: As an escaped zoo animal in an unfamiliar environment, Flaco was never expected to make it more than a week or two without food. But he learned to hunt and survive on his own, leading some local birders to believe he was better off outside of his exhibit. In Wild Inside, the documentary filmmaker reviews the circumstances of Flaco’s escape—implying that he may not have been in as good care at the zoo as one might expect (click through the link above to read more about the accusations). However, bird conservationists argue that captivity can protect non-native birds from harm, especially from rodenticide and other environmental threats that are ubiquitous in New York City.
What the experts say: Many experts didn’t agree on what was best for Flaco. “It can be easy to forget that we share urban spaces with other animals ... and that there are concrete, tractable policies that can improve their well-being,” says Jeff Sebo, director of the Center for Environmental and Animal Protection and principal investigator of the Wildlife Inclusive Local Development (WILD) Lab at New York University. “Flaco reminded us of these realities. And what we need to do now is apply that same level of concern to other urban animals, too.”
What Emma says: I’m not usually swayed by “brave animal movies.” But by the time this film was over, I was sobbing in the theater, along with pretty much everyone else. Yes, Flaco was beloved, but the greater tragedy to me was that city-dwellers can love their birds and animals so much, yet create an environment that hurts them, even when the critters beat the odds and learn to survive on our turf. —Emma Gometz, Newsletter Editor

From the May 1926 issue: "Within the burial chamber hewn from the solid rock, Tut-ankh-amen’s mummy was protected by many enclosures of wood, stone and gold. First came three large wooden, box-like shrines, one within the other. These were removed to reveal a great sarcophagus of yellow quartzite with a granite lid."

The Boundless Deep: Young Tennyson, Science, and the Crisis of Belief
By Richard Holmes. Penguin Random House, February 10, 2026.
 Poetry, history and science intertwine in this new biography of English poet Alfred Tennyson, who wrote “The Charge of the Light Brigade” and “Ulysses.” Author Richard Holmes reveals how emerging scientific understanding of the world affected Tennyson’s beliefs and in turn his work. Richard uses the poet’s life as a lens to examine how these changes impacted the way Victorian society understood its place in the universe. As someone who never turns down a history-science mash-up, I was particularly fascinated by how new concepts in biology (namely, evolution) and cosmology (namely, the vastness of space) led Tennyson to grapple with his own faith and fueled the curiosity at the core of his work. —Jennifer Hackett, Copy Editor

Today in Science reader Bob Goren sent in this cool image he took of Wednesday's solar eclipse from the Lafayette Hill neighborhood outside of Philadelphia, PA, at the height of the eclipse (for that latitude). He snapped this image with an iPhone 16 through a pair of welder's glasses. Clever!
