In Philadelphia, there was once a large public park where humans had previously intervened but where nature was reasserting itself. Residents flocked there to leave the noise and rigidity of the city grid behind and bathe in the wild unruliness of trees and meadows. This was a world unto itself, but not for long: one
MoreImagine walking on an abandoned pier in Philadelphia and entering a lush park surrounded by a mosaic of wetlands. An elegant heron jabs downward with its long, sharp beak, and you peer into the clear water to see what it’s after. Schools of fish swim over mussels amid waving green plants. This is the concept
MoreIt was a warm summer morning and shirtless, sweaty runners were just coming off the Wissahickon Trail. As they ascended out of the picturesque valley in Northwest Philadelphia to start the workday, a woman named Mary and two companions were heading the other direction, already getting down to business. Their mission looked a little like
MoreLast week, I plucked a tick off the neck of a teenager I had guided on a canoe outing. (It came off easily, not having latched on yet.) Presumably the tick had climbed on as the teen had walked through some tall grass after the boats were put away. With single-minded determination, the tick had
MoreAmong the many reporting experiences accumulated in my 13-year career as a journalist, a walk in Philadelphia’s John Heinz National Wildlife Refuge in 2022 stands out as one of the most memorable. I was invited there by various leaders from the Black birding community, who were in town to celebrate the 3rd Annual Black Birders
MoreEven the most dedicated naturalists have their boundaries when it comes to cohabitating with wildlife. And for many home gardeners, deer are enemy number one. It’s possible to acknowledge that we’ve largely taken over deer habitats and, simultaneously, feel a potent ire while watching your landscaping efforts blithely munched by these creatures. According to Penn
MoreNature enthusiasts often speak of a “spark species” that inspired their love of nature; it’s hard to think of one more popular than the monarch butterfly, which captivates thousands across North America with its flashy colors and extraordinary annual migration. These iconic butterflies hold a name brand recognition not given to most insects. We see
MoreWho 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
MoreIt’s 7:30 a.m. on a Friday in late March and Stephen Maciejewski is walking around Center City looking for dead or injured birds. He isn’t hoping to find any. But it’s spring migration, a time when millions of birds pass through the city on their way north. Maciejewski knows many of them are bound to
MoreWho 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
MoreNevermind 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
