This week we visited Monticello, the historic site and former home of Thomas Jefferson, and met "Rob," an enterprising American Robin.

Virginia Rails are not rare in Pennsylvania, but seeing one is always special. They are more often heard than seen.

On a recent camping trip, one of the most persistent songs we heard was from a Scarlet Tanager that may have been nesting right there in the campground.

Rose-breasted Grosbeaks are a common forest-nesting bird across most of Pennsylvania during late spring and summer.

We had one of the cutest yard birds visit our family's backyard last week when a female Mallard brought her three Mallard ducklings to their stream.

Three Eastern Bluebird fledglings have been visiting my bird feeders regularly. Young bluebirds are primarily brown birds with whitish spots.

I had fun last month watching a Northern Parula (a migratory warbling bird) in my favorite tree, the large white oak in my backyard.

With its yellow throat and bright yellow "spectacles," the Yellow-throated Vireo is the most colorful of the six vireo species that can be seen in Pennsylvania each year.

The Yellow-throated warbler is an active, mobile songbird that spends most of its time far from the ground on the branches of sycamore trees.

If you take a walk during the spring in a forested area near one of our streams or rivers, there is a good chance you'll hear the song of the Warbling Vireo.
