It’s no surprise that a city defined by former immigrant neighborhoods would be the gateway for yet another group of newcomers forced to gain a foothold in unfamiliar terrain. Such is the case with Carpodacus mexicanus — the house finch — which was often called the California linnet and the Hollywood finch before it was smuggled to…

With winter’s chill approaching, most birds long ago migrated south. Migration actually begins in August and continues through the milder months of September and October. Birds wing their way to more abundant food sources, with some of Pittsburgh’s species heading deep into South America to tropical climes. A few hearty species winter in…

Pittsburgh is a city of neighborhoods, and the patchwork-​quilt variety of them gives everyone a place to call home and a sense of identity to go with it. We say Shadyside, Bloomfield or the South Side, Fox Chapel, the Strip or Swissvale, and certain images, people and lifestyles come to mind. Each place…

I was listening recently to an NPR interview about an elephant researcher in Africa. It was a story about the challenge of tracking a huge and relatively abundant mammal that has the tendency to disappear into the bush in the blink of an eye. While it’s hard to imagine, it’s the way of…

Walk to the trailhead behind the Audubon Society’s Beechwood Farms nature center on Dorseyville Road, and you’ll briefly head down toward the meadow and then uphill, west, toward the upper fields. Stroll beneath the canopy of older trees until you reach the clearings. Look up, look low and listen. That black, white, and…

One fall evening in New England when I was an undergraduate, I heard honking so loud it had the force of an approaching train, lasting for several minutes as geese flew by. They faded into the night but have stayed with me since.

During our colonial period, America’s forests were felled slowly. Beginning in New England, subsistence farming and the promise of better lands to the west meant regions were settled and cleared for agriculture, then abandoned, only to regenerate. This pattern cycle of destruction and reforestation created a patchwork of fields that gave way to…

displaced Pittsburghers soon will come home again. The pigeons of Mellon Square, bumped by renovations scheduled to culminate next year, are some of my favorite birds to watch, a bit of the wild smack dab in the middle of “dahntahn.” Don’t disparage these half-​pound fast fliers.

There is a reason i am a birder and not a surgeon. As I was driving one spring, I passed something bright orange on the side of the street. I couldn’t quite make it out, but I had my suspicions. Like many birders, I’m willing to watch a bird wherever it might be:…

It’s the seventh inning stretch on a warm night at PNC Park. The sun has gone down, and the bright lights of baseball illuminate the summer sky. Downtown buildings glow across the river: Federated, Highmark, UPMC, the arched alcove of the Renaissance Hotel.
