Of the seven species of herons that nest each year in Pennsylvania, the Yellow-crowned Night Heron is one of the least common.

I was excited to learn that another birder had found a Virginia's Warbler in PA. It's the first time that species has ever been reported in Pennsylvania.

Each year in late winter and early spring, tens of thousands of Snow Geese pass through our area. Some Ross's Geese are undertaking a similar journey.

Kingbirds are flycatchers, and flying insects make up the majority of their diet. For that reason, you're not likely to see one visit a bird feeder.

In many parts of the world, Eared Grebes are common and easy to find. There are populations around the world, including one that nests in western North America.

Most terns and gulls are white, often with gray and black wings. A Black Tern stands out as one of the few with mostly black feathers.

On a recent trip, we got great looks at a pair of Black-backed Woodpeckers (we found their nest!) and a family of Canada Jays, commonly known as Whiskey Jacks.

This "Brewster's Warbler," or Golden-winged warbler, showed up in a natural area in eastern York County a few weeks ago.

My son Eddie and I got up early one morning this week to see a rare bird that was reported a few hours to the north: the Harlequin Duck.

A few days ago a birdwatcher found a MacGillivray's Warbler less than ten miles from my house.
