Melissa and I love watching Gray Catbirds at our feeders each summer. They're not the most colorful of birds, but they're energetic and social.

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.

I heard the distinctive nasal call of a Red-breasted Nuthatch this week in York County - an indication that these birds will probably be visiting our bird feeders this winter.

I found this flock of House Sparrows in a patch of dust along the side of the road at the beginning of August. It was an entertaining scene.

This juvenile Yellow-crowned Night Heron was a pleasant surprise. I was bird watching along the Susquehanna River when I found the heron perched on the hood of my car.

Listen in Pennsylvania's forests during the summer, and you may hear the persistent song of the Black-throated Green Warbler.
