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.

You're likely familiar with the three most common non-native birds in North America, but you might not have heard of the Eurasian-Collared Dove.

March and April are the best months to see Bonaparte's Gulls in the Susquehanna Valley. Like many other birds, they're on their way north this time of year.
