Beautiful and bold

It is often the voice of the Blue Jay that initially attracts our notice. With a vocal range like its cousins the crows and ravens, the Blue Jay produces loud, strident calls, bounding whistling notes, as well as imitations of the scratchy shrieks of hawks and other birds. More than once, I’ve heard…

Wintering in Pittsburgh

It may be funny to think of Pittsburgh in the same geographic thought as, say, Miami, but for dark-​eyed juncos, which spend many months to our north, we’re all sand and sunsets.

Red-​bellied woodpecker

A tree is a house. it’s not just an isolated organism, but also a host to forms of life from mammals to birds to insects to fungi. A tree is one element of a larger ecosystem and simultaneously a microcosm of it. And you can tell a lot about a neighborhood ecosystem based…

The wood duck

Changing habitat has complex consequences for birds. Some species prefer deep, old growth forests. Others thrive around patchwork clearcuts. Some require grasslands to breed, while others reproduce in swampy bottomlands. Some of our notorious losses — the ivory-​billed woodpecker and Carolina parakeet — needed relatively narrow bands of Southern wetland so much that when the trees there…

The house finch

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…

Wintering in Pittsburgh

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…

Yellow-​billed cuckoo

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…

The Brown Creeper

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…

A seasonal song

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…

The Canada goose

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.
