Nighthawk Watch
As the sky over Strawberry Mansion shifts from gold to dusky blue, something incredible starts to happen overhead — hundreds, sometimes thousands, of Common Nighthawks streaming south on one of the most electric flights of the birding calendar.
Join us for our first Nighthawk Watch of the season! Grab a blanket, bring your binoculars (or borrow a pair of ours), and settle in as we scan the darkening sky together. These sleek, erratic fliers — with their distinctive white wing bars and buzzy calls — put on a show that even lifelong birders never get tired of.
New to birding? Perfect. This is one of the easiest, most awe-inspiring ways to fall in love with fall migration. No experience needed — just curiosity and a willingness to look up.
This watch is brought to you in partnership with BirdPhilly, an initiative of the Delaware Valley Ornithological Club focused on getting Philadelphia-area residents out and interacting with nature through free, expertly guided birding trips around the city. Come meet some of the friendliest, most knowledgeable birders in the region — and maybe find your new favorite way to spend an evening outside.
Bring a chair, a snack, and someone you love. Let's watch the sky come alive.
Free and open to the public. Family-friendly.
This watch will be led by Sean Bradley. Sean Bradley is a naturalist, nature educator, and natural land steward from Philadelphia, Pennsylvania.
