Who is walking around the neighborhood while you’re not looking? Humans share the city and suburbs with a cast of other mammals that do their best to avoid us by only coming out at night. To see these shy beasts, scientists use infrared-triggered, battery-powered cameras. In a setup often called a “camera trap,” they can

Who doesn’t love lady beetles (aka ladybugs)? They are bright and cheery with that cute, round shape, plus they help gardeners by gobbling up plant-sucking aphids. There appear to be plenty of them; they’re not hard to find outside from spring through fall, and at the end of the growing season, they often make themselves

Nevermind the wildebeest of the Serengeti or the caribou of western Alaska; the greatest wildlife spectacle on Earth takes place over our heads twice a year. Early May marks the high point of the spring bird migration season, when billions of birds around the world ranging from hummingbirds to eagles work their way north. Hundreds

In mid-February, Grid requested an interview with Carlton Williams, the newly announced head of Mayor Cherelle Parker’s flagship “Clean and Green” initiative. After receiving no reply, we repeated the request a few weeks later. This time a communications official acknowledged the email, but that’s it so far. Fortunately, we’ve got other source material to examine:

From April 26 to April 29, Philadelphia and its adjacent counties will be competing against cities around the world to recruit the greatest number of people to find the most species in their regions. Using the iNaturalist app as a tool, the City Nature Challenge encourages us to explore and document the biodiversity right where

A keen observer can sometimes hear a “boom” over the row houses on summer evenings in Philadelphia. The sound marks a male common nighthawk defending his territory, flexing his wings as he dives. The insect-eating birds nest on flat, gravelly surfaces. These can be bare patches of ground in a forest, but they can also

After reading “Worn: A People’s History of Clothing,” by Sofi Thanhauser (interviewed in this issue), I went online and found a second-hand gray wool henley originally sold by a company with a reputation for well-made clothing. I wanted something I could wear this winter and for many winters to come;
